## Mimecast Advanced Email Security Reviews
  ### 1. Effective Email Security with Room for Configuration Improvement

**Rating:** 4.5/5.0 stars

**Reviewed by:** Vishnu G. | Cyber Security Associate, Mid-Market (51-1000 emp.)

**Reviewed Date:** February 12, 2025

**What do you like best about Mimecast Advanced Email Security?**

I like using Mimecast Advanced Email Security for both email security and email archiving. It effectively scans all emails, including attachments, which helps in blocking or holding emails with malicious links before they reach users, thereby protecting us from phishing attacks. I appreciate the option to release suspected emails blocked by Mimecast. During the initial setup, having vendor support made the configuration easy because they did all of it.

**What do you dislike about Mimecast Advanced Email Security?**

I feel the configuration should be more user-friendly. It's a bit complicated to whitelist particular email accounts, like our GM or CEO. It's not easy to create rules for incoming and outgoing emails for individual users. There should be an option to whitelist users so that all outgoing for a particular user shouldn't be blocked, and emails from specific users should not be blocked for specified users.

**What problems is Mimecast Advanced Email Security solving and how is that benefiting you?**

Mimecast Advanced Email Security filters emails to block malicious ones and prevent phishing. It scans attachments and provides email security and archiving. It also lets me release suspected emails, making email management safer and more efficient.

**Rating:** 4.0/5.0 stars

**Reviewed by:** Verified User in Financial Services | Mid-Market (51-1000 emp.)

**Reviewed Date:** February 14, 2025

**What do you like best about Mimecast Advanced Email Security?**

Mimecast Advanced Email Security does a good job of blocking phishing, malware, and impersonation attacks before they reach your inbox. The impersonation protection helps catch CEO fraud and spoofed emails. Setup is straightforward, and once it's running, it mostly takes care of itself. The admin dashboard has a lot of options, which can feel a bit overwhelming at first, but it gets easier to navigate over time. It’s not perfect—false positives happen now and then—but overall, it’s a solid option for keeping email threats in check.

**What do you dislike about Mimecast Advanced Email Security?**

One downside is that it can be a bit aggressive with filtering, leading to false positives that require manual review. The admin dashboard, while powerful, isn’t the most intuitive and takes some time to get used to.

**What problems is Mimecast Advanced Email Security solving and how is that benefiting you?**

Mimecast Advanced Email Security helps block phishing attempts, malware, and impersonation attacks before they reach my users inbox, reducing the risk of security breaches. The URL and attachment scanning add an extra layer of protection against malicious links and files. It also cuts down on spam, which keeps my inbox cleaner and more manageable.

Mimecast is mandatory to stop the troves of spam and phishing sent to emails scraped off our website.

**Reviewed by:** Michael B. | Head of Technology & Innovation, Mid-Market (51-1000 emp.)

**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?**

There 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 hasnt 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.

  ### 16. Mimecast is a daily system we utilize

**Rating:** 4.5/5.0 stars

**Reviewed by:** Ricky D. | Systems Administrator, Mid-Market (51-1000 emp.)

**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.

  ### 17. No more phishing headaches

**Rating:** 4.5/5.0 stars

**Reviewed by:** Simon R. | IT security manager, Internet, Small-Business (50 or fewer emp.)

**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.

  ### 18. Mimecast is great for archive

**Rating:** 4.0/5.0 stars

**Reviewed by:** Verified User in Higher Education | Enterprise (> 1000 emp.)

**Reviewed Date:** February 14, 2024

**What do you like best about Mimecast Advanced Email Security?**

Sometimes hard to find emails in search. Mimecast occasionally will "hold" legitimate emails.

Helps keep our email safe and archived.

  ### 19. Capable and robust, if a little complex

**Rating:** 4.5/5.0 stars

It's good at keeping our email safe. It's doing what it says it'll do

**What do you dislike about Mimecast Advanced Email Security?**

The UI and some of the way things are configured are a bit too complex.

Flagging suspicious email, blocking spam, etc

  ### 20. Easy to Manage Advanced Email security

**Rating:** 4.5/5.0 stars

**Reviewed by:** Verified User in Insurance | Mid-Market (51-1000 emp.)

**Reviewed Date:** September 16, 2024

**What do you like best about Mimecast Advanced Email Security?**

Mimecast Advanced Email Security is a great tool to add a layer of protection to corporate email solution, it has lots features which cover many elements of an emails journey and contents giving our end users confidence when working with email. 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 recieve functionality. Users are able to self assess held of flagged emails and decide whether they think they are safe or malicious based on Mimecasts 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 administation 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.)

**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. The Tortoise Eventually Wins

**Rating:** 3.5/5.0 stars

**Reviewed by:** Ben S. | Head of Technology, Mid-Market (51-1000 emp.)

**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 thos einstances. Our more frequent users have also had problems with TTP enrolment, another issue outside of Mimecasts'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.

  ### 23. Mimecast Advanced Email Security

**Rating:** 3.5/5.0 stars

**Reviewed by:** Jessica C. | Chief Technology Officer, Mid-Market (51-1000 emp.)

**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.

  ### 24. Great email management platform

**Rating:** 5.0/5.0 stars

**Reviewed by:** Verified User in Legal Services | Mid-Market (51-1000 emp.)

**Reviewed Date:** September 19, 2024

**What do you like best about Mimecast Advanced Email Security?**

Good scanning,very few false positives and searchability is invaluable for SARS etc. Use its archive functionality almost daily and was very easy to implement. We utilise pretty much everything mimecast offer. We have it integrated into outlook which has pros and cons, dont like the restore function as its limited to one year when searching as as user but general usage its fine.

**What do you dislike about Mimecast Advanced Email Security?**

Interface can sometimes be difficult to navigate between polices especially in regards to attachment management.

**What problems is Mimecast Advanced Email Security solving and how is that benefiting you?**

Removes a huge amount of administration time from the team and provides a easy to use search and discover function. clear as to why an email has been held and what policies it has passed and the one that it has failed on.

  ### 25. We have significantly improved email protection and productivity in our company

**Rating:** 4.0/5.0 stars

**Reviewed by:** Laura C. | Senior Data Analyst, Civic & Social Organization, Small-Business (50 or fewer emp.)

**Reviewed Date:** July 20, 2024

**What do you like best about Mimecast Advanced Email Security?**

In my opinion, what sets Mimecast Advanced Email Security apart is the comprehensive protection of emails that it offers. It integrates well with Office 365 and boosts our security while doing so without any fuss. One is the real time threat intelligence which is impressive in keeping abreast of new threats. Its spam filter works very well, cutting the number of spam emails to a great extent. This has indeed enhanced our cybersecurity since this software is easy to use and the security measures employed are very effective.

**What do you dislike about Mimecast Advanced Email Security?**

A major drawback in Mimecast Advanced Email Security is that the spam filter occasionally mistakes genuine messages for spam, effectively holding the emails hostage until the problem is manually sorted out. This has affected the way we work as often there is need to check the spam folder. Also, it was no easy task to complete the configuration of the first level as compared to the second level, which was a complex affair and took considerable time of effort from our IT department.

**What problems is Mimecast Advanced Email Security solving and how is that benefiting you?**

Mimecast Advanced Email Security has successfully addressed our concerns on phishing and malware, delivering an excellent solution for email security. Real time threat intelligence and spam filtering have been of great help in enhancing our cybersecurity. It also has a positive impact for our IT team because they are relieved from so many security incidents and can manage more important tasks. Further, there has been a decrease of spam and phishing attempt which has improved productivity and safer communication generally.
