This reviewer was offered a nominal incentive as thanks for completing this review. **Reviewed Date:** September 17, 2024 **What do you like best about Mimecast Advanced Email Security?** Overall, I value the security, flexibility, and user-friendly nature of Mimecast Advanced Email Security. It is a powerful tool for protecting email communications. It allows me to set customised policies that align with my firm's specific needs. Whether it's scanning attachments, monitoring URLs, or filtering emails based on specific content, the flexibility is excellent. **What do you dislike about Mimecast Advanced Email Security?** Mimecast sometimes flags legitimate emails as suspicious, leading to delays in communication. While it’s good at catching threats, managing false positives can become tedious. While the interface is generally intuitive, new users can face a learning curve, particularly in understanding the more nuanced security policies and tools within the platform. Training or familiarisation may be required to fully leverage its potential. There are some advanced configurations that can feel quite complex. Setting up intricate rules can be more time consuming and require more expertise than expected. **What problems is Mimecast Advanced Email Security solving and how is that benefiting you?** It is resolving the following for us :- Phishing and Impersonation Attacks Malware and Ransomware Protection Data Loss Prevention Email Continuity and Archiving Spam and Junk Filtering ### 5. Amazing product, friendly interface, zero account management **Rating:** 4.5/5.0 stars **Reviewed by:** Rod D. | IT Director, Mid-Market (51-1000 emp.) **Current User:** The reviewer uploaded a screenshot or submitted the review in-app verifying them as current user. **Validated Reviewer:** Validated through a business email account **Incentivized:** This reviewer was offered a nominal incentive as thanks for completing this review. **Source: Seller invite:** Invitation from a seller or affiliate. This reviewer was offered a nominal incentive as thanks for completing this review. **Reviewed Date:** September 17, 2024 **What do you like best about Mimecast Advanced Email Security?** The best thing about Mimecast is how easy it is to manage and implement. From all the basics of emails protection like allow/deny lists, to more advanced features like greylist checks and DMARC rules, it does all from a very friendly interface and once you get used to its logic, the daily usage of IT admins, to the sporadic use by end users just makes this product probably the best in class on its market. **What do you dislike about Mimecast Advanced Email Security?** The only caveat to something so ease to integrate and manage is the customer support and account management that is often lacking. Customer support is not always helpful, or will only provide a link to their knowledgebase rather than helping with troubleshooting, and it's very hard to find anyone on the account management side of the house that can be a point of contact for escalations, renewals, and so on. **What problems is Mimecast Advanced Email Security solving and how is that benefiting you?** Managing permit/block lists based on return-path or sending domain, blocking spam, creating rules, all on an easy-to-manage interface, with granular permissions that allows service desk roles to do the basic and level 3 admins to manage complex rules. ### 6. It's amazing how many emails it stops for us! **Rating:** 5.0/5.0 stars **Reviewed by:** Drew B. | Systems Administrator, Mid-Market (51-1000 emp.) **Current User:** The reviewer uploaded a screenshot or submitted the review in-app verifying them as current user. **Validated Reviewer:** Validated through LinkedIn **Incentivized:** This reviewer was offered a nominal incentive as thanks for completing this review. **Source: Seller invite:** Invitation from a seller or affiliate. This reviewer was offered a nominal incentive as thanks for completing this review. **Reviewed Date:** September 13, 2024 **What do you like best about Mimecast Advanced Email Security?** The automated spam screening is probably the best feature as I do not need to worry about emails that fail graylisting, are in RBL, ones that Mimecast detects as having spam content, and email addresses/domains that users themselves want to be blocked.

The customisation of the policies is fantastic too and really allows us to easily finetune what actions we want taking on certain emails and allows us to override it when we do not want action to be taken.

Customer support is really good and the documentation available is useful. I have also completed the Mimecast University and I would recommend this to anyone who is administrating Mimecast.

The large file send and secure message send are part of our business practices now and we feel safe knowing that these types of emails are sent correctly and securely, and with automatically generated instructions to the recipients so we don't need to explain to them what to do. **What do you dislike about Mimecast Advanced Email Security?** The upgrades last year to the administrator console were in my opinion a bit of a downgrade. I have given it time to settle in my mind, but I liked having the tabs open rather than having to open a tab on my browser. **What problems is Mimecast Advanced Email Security solving and how is that benefiting you?** Spam, sharing large emails, sending secure emails, phishing attempts, email archiving ### 7. Policies work well, Anti-spam not so much. **Rating:** 5.0/5.0 stars **Reviewed by:** Mitchell Y. | Network & Systems Engineer, Small-Business (50 or fewer emp.) **Current User:** The reviewer uploaded a screenshot or submitted the review in-app verifying them as current user. **Validated Reviewer:** Validated through a business email account **Incentivized:** This reviewer was offered a nominal incentive as thanks for completing this review. **Source: G2 invite on behalf of seller:** Invitation from G2 on behalf of a seller or affiliate. This reviewer was offered a nominal incentive as thanks for completing this review. **Reviewed Date:** February 06, 2025 **What do you like best about Mimecast Advanced Email Security?** Mimecast is mandatory to stop the troves of spam and phishing sent to emails scraped off our website. **What do you dislike about Mimecast Advanced Email Security?** The spam detection has many false positives. Although it is good to lean that direction with detection, it still has many false negatives that get through the cracks. Both are issues that I have to deal with manually. **What problems is Mimecast Advanced Email Security solving and how is that benefiting you?** Benefits us by reducing manual email spam checks, and relies less on the user's ability to sift through spam emails. ### 8. A Robust and Reliable Solution for Comprehensive Email Protection **Rating:** 5.0/5.0 stars **Reviewed by:** Andrew M. | Cyber Security Architect, Information Technology and Services, Mid-Market (51-1000 emp.) **Current User:** The reviewer uploaded a screenshot or submitted the review in-app verifying them as current user. **Validated Reviewer:** Validated through LinkedIn **Incentivized:** This reviewer was offered a nominal incentive as thanks for completing this review. **Source: Seller invite:** Invitation from a seller or affiliate.

The Customer Support is very knowledgable and gets back to us in a timely manner. **What do you dislike about Mimecast Advanced Email Security?** At times, legitimate emails get flagged as spam or potential threats, requiring manual intervention to release them.

They may not have updated their review text, but have updated their review. **What do you like best about Mimecast Advanced Email Security?** The benefits of using Mimecast are ease of setup, ease of admin & its one product that truly does what it claims and just works. Once it's setup it's really set and forget and you don't have to be continually checking in on it **What do you dislike about Mimecast Advanced Email Security?** I have not had any dislikes with the Mimecast product. The only feedback I could give is that if you use their other products like Cyber Awareness training there is a different console to administer from. **What problems is Mimecast Advanced Email Security solving and how is that benefiting you?** Mimecast solves our spam issues as we have less than 0.01% of spam email delivered to our users. ### 11. Industry leader for Secure Email Gateway (SEG) providers **Rating:** 4.5/5.0 stars **Reviewed by:** Michael B. | Head of Technology & Innovation, Mid-Market (51-1000 emp.) **Current User:** The reviewer uploaded a screenshot or submitted the review in-app verifying them as current user. **Validated Reviewer:** Validated through LinkedIn **Incentivized:** This reviewer was offered a nominal incentive as thanks for completing this review. **Source: G2 invite on behalf of seller:** Invitation from G2 on behalf of a seller or affiliate. This reviewer was offered a nominal incentive as thanks for completing this review. **Reviewed Date:** August 08, 2024 **What do you like best about Mimecast Advanced Email Security?** Extremely robust and granular controls over every policy and potential vector that attackers will try and use to compromise your end users via email. They also have integration into other platforms via their API for security events if you operate a SIEM or have a SOC service. Finally a retention policy which means you never have to worry about email backups again...we have 99 years! **What do you dislike about Mimecast Advanced Email Security?** Their product roadmap appears to have slowed down somewhat as of late. Features and enhancements were very regular cadence..but as of 2024, not so much. Example: Their Outlook plugin hasn't had an update since 2022. They are clearly pivoting to sectors such as Human Risk & Behaviour based products, which may have resulted in slowing down development of their core SEG product. **What problems is Mimecast Advanced Email Security solving and how is that benefiting you?** Protecting all my end users from malicious emails and attachments automatically but also empowering end users to self-service for email retention and search or releasing emails that have been caught in digest, so that IT don't have too. ### 12. Mimecast is a daily system we utilize **Rating:** 4.5/5.0 stars **Reviewed by:** Ricky D. | Systems Administrator, Mid-Market (51-1000 emp.) **Current User:** The reviewer uploaded a screenshot or submitted the review in-app verifying them as current user. **Validated Reviewer:** Validated through a business email account **Incentivized:** This reviewer was offered a nominal incentive as thanks for completing this review. **Source: G2 invite on behalf of seller:** Invitation from G2 on behalf of a seller or affiliate. This reviewer was offered a nominal incentive as thanks for completing this review. **Reviewed Date:** August 08, 2024 **What do you like best about Mimecast Advanced Email Security?** There are so many features for Mimecast that we use daily, it is hard to summarize what we like best. I will instead highlight one feature that we like, however is not "the best" one. That feature is the ability to create customized filters for emails. Mimecast assists our company by filtering out most, if not all credit card information sent via email. Being PCI compliant, this is key for our company to do the absolute best to prevent sensitive data from being transmitted.
I was not involved with the implementation, however I have had to use support a couple of times and those times yielded a quick response each time. **What do you dislike about Mimecast Advanced Email Security?** there is not much to say, however if there was a way to not require MFA on every login on the same device that would be great. **What problems is Mimecast Advanced Email Security solving and how is that benefiting you?** The advanced email filtering and scanning helps our org so that we do not have to rely solely on Microsoft exchange in doing the entire job. ### 13. No more phishing headaches **Rating:** 4.5/5.0 stars **Reviewed by:** Simon R. | IT security manager, Internet, Small-Business (50 or fewer emp.) **Validated Reviewer:** Validated through a business email account **Incentivized:** This reviewer was offered a nominal incentive as thanks for completing this review. **Source: G2 invite on behalf of seller:** Invitation from G2 on behalf of a seller or affiliate. This reviewer was offered a nominal incentive as thanks for completing this review. **Reviewed Date:** October 20, 2024 **What do you like best about Mimecast Advanced Email Security?** The speaking point about Mimecast that I like most is a rich number of options for email protection. The usage of filtration and blocks against getting spam and malware has been often useful in this software. Its strong attachment and URL scanning features make it possible to have the assurance that all kinds of email hazards are dealt with. The software also makes sure that our data never gets to be breached while we are still working and this has been a plus for us. **What do you dislike about Mimecast Advanced Email Security?** I have one issue with Mimecast, and it is that it is a program that likes to mark genuine emails as threats. Frequent arguments and postponements occur and essential messages are isolated leading to more frequent chaos. Number of false positive has affected our workflow greatly in that we spend a lot of time reviewing them. This is especially disruptive when it comes to communicating with clients and partners – it can be quite inconvenient when, for example, we are up against a certain deadline. **What problems is Mimecast Advanced Email Security solving and how is that benefiting you?** Mimecast has been very good in addressing the issue of having to deal with ongoing email born threats such as phishing and malware. Earlier, we often fell victim to phishing scams which posed high risks to our data. These threats are effectively prevented by its regular scanning and comprehensive protection, so we can work more confidently. We do not experience any disturbances from the side of email security, the team is more devoted to business processes rather than security ones. ### 14.

This happens with a number of our admin users. Initial setup was quite complicated **What problems is Mimecast Advanced Email Security solving and how is that benefiting you?** The system provides our email security and archiving solution. It means we can easily manage our systems via a cloud based platform ### 16. Reliable, robust, feature rich and always innovating **Rating:** 5.0/5.0 stars **Reviewed by:** Michael Y. | IT Manager, Mid-Market (51-1000 emp.) **Current User:** The reviewer uploaded a screenshot or submitted the review in-app verifying them as current user. **Validated Reviewer:** Validated through a business email account **Incentivized:** This reviewer was offered a nominal incentive as thanks for completing this review. **Source: Seller invite:** Invitation from a seller or affiliate. This reviewer was offered a nominal incentive as thanks for completing this review. **Reviewed Date:** September 13, 2024 **What do you like best about Mimecast Advanced Email Security?** I appreciate the real-time view of email using the tracking feature. Being able to see immediately the receipt of emails and how they are being assessed is really important. Also, the great range of security features make me comfortable that Mimecast is protecting us. **What do you dislike about Mimecast Advanced Email Security?** Not much to dislike. It has all the features and services I care about in email security, with a few extras our users love, like Large File Send. **What problems is Mimecast Advanced Email Security solving and how is that benefiting you?** Mimecast is scanning and detecting threats to our inbound email. These threats range from typical AV infected emails, to phishing, to impersonation attempts, to URL hijacking.

Mimecast is an outstanding product for great value for money **Rating:** 4.5/5.0 stars **Reviewed by:** Verified User in Staffing and Recruiting | Mid-Market (51-1000 emp.) This reviewer's identity has been verified by our review moderation team. They have asked not to show their name, job title, or picture. **Current User:** The reviewer uploaded a screenshot or submitted the review in-app verifying them as current user. **Validated Reviewer:** Validated through a business email account **Incentivized:** This reviewer was offered a nominal incentive as thanks for completing this review. **Source: Seller invite:** Invitation from a seller or affiliate. This reviewer was offered a nominal incentive as thanks for completing this review. **Reviewed Date:** September 23, 2024 **What do you like best about Mimecast Advanced Email Security?** We use mimecast as an email gateway in which we connect a number of exchange servers too, which is easy to connect up too and synchronises with our Active Directory. I am an administrator and I regularly use Mimecast to support our group. The user interface is easy to get around to investigate email delivery as well as reports on nasty emails. The biggest positive of Mimecast is the protection against spam emails, where it captures 99% of spam as well as many phishing attempts and malicious emails. This and many of Mimecasts other features such as stationary, email archive and reports, makes Mimecast a valuable product to our organisation for excellent value. We rarely require support from customer services, but when we do, they are supportive and help us fix any issues. **What do you dislike about Mimecast Advanced Email Security?** There is not a lot I dislike about Mimecast Email Security so this is probably nit picking a bit. Where I say Mimecast captures 99% of the spam, it would be the 1% that gets through where our users will assume it is safe and get caught out by the trap. I don't think any Email Security system would be 100% but would be nice if those 1% if emails included a mimecast warning that this could be a malicious attempt. The Mimecast Administration console has vastly improved over the last year or so making it easier to navigate. The only issue I have is sometimes when reports are loading, it would be nice to see a loading bar or spinning circle or something to signify that Mimecast is working on it. **What problems is Mimecast Advanced Email Security solving and how is that benefiting you?** Our organisation sends and receives a lot of emails, without mimecast our users would be inundated with spam and malicious emails. The sandboxing and hold boxes provide our staff with the ability to check flagged emails without the need for me to do anything. The policies are straightforward and can be applied to groups of people as well as individuals. With our current setup, new staff can be added to our systems without any need of any further configuration as it is automatically handled with Mimecast. I rarely need to do anything on Mimecast other than look at reports because the product is setup and does everything automatically. ### 18.

Additionally, the value for money is outstanding—considering the high level of protection, the return on investment has been significant. **What do you dislike about Mimecast Advanced Email Security?** To be completely honest, after nearly two years of using Mimecast, we haven’t found anything that stands out as a negative. The platform has consistently delivered on its promises, and we’ve had a smooth experience from day one. If anything, the only challenge might be that some of the more advanced features take a little time to fully explore and utilize, but the support team is always readily available to assist with this.

Now, those threats are effectively filtered and blocked, giving us greater peace of mind.

Another major benefit is email continuity. Mimecast ensures that even during outages, we have uninterrupted access to our email systems. This has been invaluable for our team, as it minimizes downtime and keeps us productive.

Lastly, Mimecast's archiving capabilities have been a huge asset. We're able to store and retrieve email communications easily, ensuring compliance and allowing for seamless auditing when needed. Overall, Mimecast has improved our email security posture and helped us stay focused on our work without worrying about threats. ### 20.

It is easy to implement and once set up requires little intervention from IT staff in the day to day management of email send and receive functionality. Users are able to self assess held or flagged emails and decide whether they think they are safe or malicious based on Mimecast's recommendations.

Mimecast Advanced Email Security integrated straight into our Microsoft365 tenancy with very little effort and the Outlook add-in allows a further level of integration and convenience to the end user.

Mimecast Support has improved vastly over the years we have been a customer, it is now a very quick and easy way of sorting out any issues that do arise. **What do you dislike about Mimecast Advanced Email Security?** Mimecast Advanced Email Security can take some time to tailor the impact on end users to begin with. Time and effort is needed to construct the correct whitelists and exceptions, as well as adjusting the spam filters to avoid an excessive amount of email being incorrectly held. The only other drawback is the usability of the administration portal, features and their policies can be hard to find as there are quite a few different levels to each function. **What problems is Mimecast Advanced Email Security solving and how is that benefiting you?** Since the introduction of Mimecast Advanced Email Security in our business we have seen a massive reduction in phishing and other malicious emails being delivered to users' inboxes. On top of the reduction of risk associated with this, we have also seen our users become much more aware of suspicious emails thanks to the messaging they see from the Mimecast product. The IT team now spends a lot less time in the administration and 'checking' of emails coming into the business, it has enabled our users to be more self-sufficient and confident in what they are responding to. ### 21. Great Application but confusing polices config. **Rating:** 3.5/5.0 stars **Reviewed by:** Verified User in Non-Profit Organization Management | Mid-Market (51-1000 emp.)

This reviewer was offered a nominal incentive as thanks for completing this review. **Reviewed Date:** September 12, 2024 **What do you like best about Mimecast Advanced Email Security?** I have been using Mimecast advanced Email security for almost two years now and use it almost everyday. The Best feature I would say is its robust policies and variety of polcies which covers all the of threate coming from email. It has the best URL protection complemented by Sandboxing. The implementaion was also easy thanks to their support staffs and Integration with m365 was easy. **What do you dislike about Mimecast Advanced Email Security?** One of the main frustrations with Mimecast Advanced Email Security is its not so perfect New Outlook addin. It requires continous loggin and it doesn't work as good as the old Outlook Plugin. The variety of policies also makes it difficult to track and configure new policies, making it confusing. This lack ease in policy configuration can slow down the process and require extra effort to manage effectively, having to contact Mimecast Support everytime but the support is always helpful which is a plus. **What problems is Mimecast Advanced Email Security solving and how is that benefiting you?** Mimecast is benefiting us with anti spoofing, blocking spams, malwares and links basically helping our org and staff be sage in Outlook. ### 22. Simple, intelligent and powerful email security gateway **Rating:** 5.0/5.0 stars **Reviewed by:** Amritpal G. | IT Manager, Mid-Market (51-1000 emp.) **Current User:** The reviewer uploaded a screenshot or submitted the review in-app verifying them as current user. **Validated Reviewer:** Validated through a business email account **Source: Seller invite:** Invitation from a seller or affiliate. This reviewer was not provided any incentive by G2 for completing this review. **Reviewed Date:** June 24, 2024 **What do you like best about Mimecast Advanced Email Security?** Mimecast is pretty straightforward to set up, yes absolutely it's a technical platform but it still ticks a lot of boxes. We were getting really hammered by standard end-user email platforms sending numerous emails spoofing our CEO and it got to the point that we were concerned that we only had to have one of those phishing emails hit hard for our reputation to be very hurt. We opted for Mimecast and boom - no more silly emails. We also send many outbound emails via Amazon SES and Mimecast is brilliant at accommodating this for us, so it honestly ticks so many boxes and maintains security. A quick note on onboarding and support, for years I've used Mimecast and have always been really delighted with the technical and interpersonal skills of their engineers. Really brilliant service all round, and prompt responses whenever I need a guiding hand for configuring stuff or something doesn't quite click in my head and needs explaining. **What do you dislike about Mimecast Advanced Email Security?** We opted for the Mega-Plan and it integrates pretty well, it does need a few Azure Enterprise Apps to be plugged in to work. A few minutes work, not a massive biggie. **What problems is Mimecast Advanced Email Security solving and how is that benefiting you?** Preventing a small horde of spammer and whalers from getting through the door to 'speak' to my users, per-user ACLs also ensure I can have exactly the right people getting the right e-mails without opening the door for everyone in the company to receive from that domain. We also didn't previously have email-archiving which I thought was crazy and Mimecast has helped ease my fears on that count, we also use it for more practical things such as identifying emails sent to leaver accounts which Microsoft would outright reject (or make awful to search for). **Official Response from Sarah Burke:** > We have a number of integration partners that we work with that can help give you additional visibility. We always recommend customers to integrate and also tell us what they would like to integrate on our ecosystem page in Mimecaster Central. ### 23.

This reviewer was offered a nominal incentive as thanks for completing this review. **Reviewed Date:** June 19, 2024 **What do you like best about Mimecast Advanced Email Security?** The great thing about Mimecast Advanced Email Security is that it works. Virus screening, spam screening, targeted threat protection and even phishing awareness - all of this works, with a relatively control panel that is easy to use. Implementation is relatively simple, as is integration with our on-premise Exchange server. **What do you dislike about Mimecast Advanced Email Security?** The performance can be somewhat lacking, and over the past year or so, Mimecast have faced a number of issues outside of their control. Spam activity from customers who are sending out bulk mail have resulted in our own emails being rejected by spam-blacklists, but Mimecast customer support have been responsive and helpful in those instances. Our more frequent users have also had problems with TTP enrolment, another issue outside of Mimecast's control, but one that has led to some of my more senior users complaining about the service. **What problems is Mimecast Advanced Email Security solving and how is that benefiting you?** Mimecast helps to protect my organisation. It serves as an essential safeguard against those occasions where staff click the wrong link or open the wrong attachment. ### 24.

This reviewer was offered a nominal incentive as thanks for completing this review. **Reviewed Date:** June 25, 2024 **What do you like best about Mimecast Advanced Email Security?** I like the ease of knowing that potential and known malicious e-mails are stopped from being delivered to the end user. Easy to use and give a lot of insight into the threats that are part of your e-mail attack surface. For the most part the implementation is easy, until you need to configure specific rules and policies that are specific to an organization. We use it daily to look at the held e-mails and review what is undeliverable via the rules and policies. Easily integrates with M365. **What do you dislike about Mimecast Advanced Email Security?** The downside is the support is a little offputting, if you are past your implementation phase. Some of the rule and policies are hard to configure through implementation. **What problems is Mimecast Advanced Email Security solving and how is that benefiting you?** Lessening the attack vector for the end user, by stopping most of the malicious e-mails that are phishing attempts. ### 26.

It also manages all elements of email security/filtering. We also use it as a mail server for 3rd party apps that need to send emails using our domains. ### 42. The best email filtering solution on the market! **Rating:** 5.0/5.0 stars **Reviewed by:** Dylan B. | System Administrator, Mid-Market (51-1000 emp.) **Current User:** The reviewer uploaded a screenshot or submitted the review in-app verifying them as current user. **Validated Reviewer:** Validated through a business email account **Incentivized:** This reviewer was offered a nominal incentive as thanks for completing this review. **Source: G2 invite on behalf of seller:** Invitation from G2 on behalf of a seller or affiliate.

Constantly getting updated with new features and capabilities. Good outlook integration **What do you dislike about Mimecast Advanced Email Security?** New menu & cosmetic designs in the administration side aren't always better, and some have made it significantly worse. **What problems is Mimecast Advanced Email Security solving and how is that benefiting you?** Fewer false detections and high rate of detecting malicious email save alot of time. ### 43. Generally a solid core product but support and onboarding are mediocre **Rating:** 3.5/5.0 stars **Reviewed by:** Verified User in Pharmaceuticals | Mid-Market (51-1000 emp.) This reviewer's identity has been verified by our review moderation team.

This reviewer was offered a nominal incentive as thanks for completing this review. **Reviewed Date:** June 24, 2024 **What do you like best about Mimecast Advanced Email Security?** The security gateway is a very robust and highly customizable solution. Once you have it up and running it functions quite well and does a good job of stopping threats. It layers well with Google Workspaces, once you have it up and running. Users find the security awareness training videos quite entertaining and the short format helps with compliance. Users find it fairly easy to self-service their quarantines after a little training, saving on admin work. **What do you dislike about Mimecast Advanced Email Security?** Support is knowledgeable but I get the impression they are very overtaxed. The onboarding process was a slog, we purchased the integration assistance, but it took weeks for our implementation specialist to actually reach out to us, by that time we had already started configuring the product ourselves. I would strongly recommend purchasing the implementation assistance, especially if you plan to use this with Google Workspaces. It's a rather involved process and you're going to have a bad time if (when) something goes wrong as the implementation docs are rather terse. The product also requires quite a lot of fine-tuning and adjustment in the first few weeks, so expect some degree of complaints from your users. Again, having the assistance of the implementation specialist is key here otherwise you'll need to deal with T1 support which is not always the most helpful or responsive. The SAT dashboards are pretty but a bit sparse. Getting simple information like a list of non-compliant users is more work than it should be. Google Workspace integration is also a little bare-bones. It would be nice for users to be able to report messages via the Gmail interface instead of the Mimecast portal. **What problems is Mimecast Advanced Email Security solving and how is that benefiting you?** Securing our email from outside threats and Security Awareness Training. It's definitely another layer of security preventing our users from engaging in risky online behavior. ### 44. Robust enterprise email security solutions **Rating:** 4.5/5.0 stars **Reviewed by:** Wade C. | Information Security & User Experience, Mid-Market (51-1000 emp.) **Current User:** The reviewer uploaded a screenshot or submitted the review in-app verifying them as current user. **Validated Reviewer:** Validated through LinkedIn **Incentivized:** This reviewer was offered a nominal incentive as thanks for completing this review. **Source: G2 invite on behalf of seller:** Invitation from G2 on behalf of a seller or affiliate. This reviewer was offered a nominal incentive as thanks for completing this review. **Reviewed Date:** June 22, 2024 **What do you like best about Mimecast Advanced Email Security?** Mimecast advanced email Security gives me peace of mind knowing that our associate's mailboxes are protected against malicious email threats and attempts to disrupt our business. Having email filtering, encryption and archiving all in one solution just makes sense. Mimecast support and account managers have always taken care of us to ensure our solution is configured and functioning as intended. **What do you dislike about Mimecast Advanced Email Security?** Admittingly, it's not the easiest solution to manage, but the more time you spend in it the easier it is to administer and understand for a system as complex as it is. **What problems is Mimecast Advanced Email Security solving and how is that benefiting you?** Protection against ransomware and other email threats, including protecting our clients information when sending externally and using the encryption feature. ### 45. Overall a strong product with a mostly hands off approach. **Rating:** 4.0/5.0 stars **Reviewed by:** Verified User in Hospitality | Enterprise (> 1000 emp.) This reviewer's identity has been verified by our review moderation team. They have asked not to show their name, job title, or picture. **Current User:** The reviewer uploaded a screenshot or submitted the review in-app verifying them as current user. **Validated Reviewer:** Validated through LinkedIn **Incentivized:** This reviewer was offered a nominal incentive as thanks for completing this review. **Source: G2 invite on behalf of seller:** Invitation from G2 on behalf of a seller or affiliate. This reviewer was offered a nominal incentive as thanks for completing this review. **Reviewed Date:** August 08, 2024 **What do you like best about Mimecast Advanced Email Security?** The product as a whole integrates well into our environment and does a very good job of detecting possible threats and scanning URLs. For end users and for most aspects of its configuration it has a high ease of use and ease of implementation. **What do you dislike about Mimecast Advanced Email Security?** When hands-on intervention is needed, the organization of their UI could be much better as it is confusing at times where to go to resolve the issue as many dashboards have similar names/functions but are just different enough to not work the way you expect. Customer support is also usually slow at responding to issues. **What problems is Mimecast Advanced Email Security solving and how is that benefiting you?** General email security, preventing phishing attempts, preventing unsafe file attachments, preventing impersonation attempts. It cuts down on the amount of phishing attempts seen by our users exponentially. ### 46.

They may not have updated their review text, but have updated their review. **What do you like best about Mimecast Advanced Email Security?** Mimecast works well, and their AI system of learning normal communications is a huge help in detecting unusual activity. We were with a different product before and it was always giving us grief. As soon as we went to Mimecast all our problems went away immediately. Good admin consoles for fast in and out changes. **What do you dislike about Mimecast Advanced Email Security?** Finding some items in the Admin Console is a little disjointed. I am jumping around to different areas for basic admin tasks. **What problems is Mimecast Advanced Email Security solving and how is that benefiting you?** We needed a much more reliable spam detection engine that was not constantly disrupting our employees. We needed both a Gateway and an API backend solution for a full-featured security approach. ### 47. Mimecast Advanced Email Security Hands-On Review **Rating:** 3.5/5.0 stars **Reviewed by:** Verified User in Manufacturing | Mid-Market (51-1000 emp.) This reviewer's identity has been verified by our review moderation team. They have asked not to show their name, job title, or picture. **Current User:** The reviewer uploaded a screenshot or submitted the review in-app verifying them as current user. **Validated Reviewer:** Validated through a business email account **Incentivized:** This reviewer was offered a nominal incentive as thanks for completing this review. **Source: G2 invite on behalf of seller:** Invitation from G2 on behalf of a seller or affiliate. This reviewer was offered a nominal incentive as thanks for completing this review. **Reviewed Date:** June 19, 2024 **What do you like best about Mimecast Advanced Email Security?** I like the granularity and control you can have via the many definitions and policies that are possible. Policies are generally easy to implement themselves and the documentation and tools tips are very useful. Mimecast offer a quarterly health check to ensure that the config still meets best practices and to advise if any new features have been released since the last review. Support from the customer success manager is great and also when logging tickets with main support team, I have always found responses to be insightful and not simply, just read this KB (though of course, KBs are referenced). **What do you dislike about Mimecast Advanced Email Security?** Whilst there are many different policies that can be implemented, it can be tricky to know which ones you maybe should be implementing and those which are more niche. Perhaps filtering them in this kind of way would be useful. I know policies will differ between companies, but I suspect most would at least want a consistent best practice baseline to begin with and then tweak as they move forward. Additionally, whilst you can give policies a "narrative" to define what that policy is for, I would like to see a description field to be able to write more information. For example, you can have bypass rules for specific IPs, but it's not easy to document whose IPs those are, so you end up with potentially multiple IP bypass rules so you can name each one, whereas if there was a description field, you could possibly have just a single IP bypass rule. **What problems is Mimecast Advanced Email Security solving and how is that benefiting you?** We receive many spam related emails which Mimecast does a great job of holding back from the user. It also does a great job with its impersonation protection and spoof detection to block many malicious emails, however, it does currently suffer from compromised email detection, where if the compromised email does not send links or attachments but maybe just a request to switch communication platforms (i.e. move to WhatsApp), it can be difficult to block. Keywords / phrases can be configured, but that is all based on guessing what an email may contain. I believe Mimecast are working on a solution to this moving forward. ### 48.

All the tools our end users need to be secure. **What do you dislike about Mimecast Advanced Email Security?** With high-end tools comes complexity. Because of the complexity, it can be challenging to configure. **What problems is Mimecast Advanced Email Security solving and how is that benefiting you?** Our main security needs after the standard email security are HIPAA and PCI, which Mimecast does very well for us. It's topped off with secure large file send and encrypted messages. ### 50.
