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. Review collected by and hosted on G2.com.

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.

It's good at keeping our email safe. It's doing what it says it'll do Review collected by and hosted on G2.com.

The UI and some of the way things are configured are a bit too complex. Review collected by and hosted on G2.com.

What stands out most about Mimecast is how comprehensive yet simple it is. Despite the platform’s powerful and robust email security features, it's incredibly easy to use. The interface is so intuitive that anyone, regardless of technical background, can navigate and manage it effectively. This has been a game changer for our team, as we can focus on our core tasks while Mimecast silently but effectively guards our email communications.

Another huge benefit is their exceptional support. From the start, their team was dedicated to ensuring we understood every feature. The onboarding experience was particularly impressive – they didn’t just set us up and leave; they were there every step of the way to make sure we were comfortable with the system and maximizing its potential. Their commitment to customer care is something that truly sets them apart.

The Upsides

The upsides of using Mimecast are numerous. For us, it’s been a reliable shield against a variety of email threats like phishing attacks, malware, and spam. Knowing that our data and communications are protected gives us peace of mind. Additionally, the value for money is outstanding—considering the high level of protection, the return on investment has been significant. Review collected by and hosted on G2.com.

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.

Overall, there hasn’t been anything we’ve found unhelpful—Mimecast has been a reliable and essential tool for our organization. Review collected by and hosted on G2.com.

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 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. Review collected by and hosted on G2.com.

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.

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. Review collected by and hosted on G2.com.

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.

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.

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. Review collected by and hosted on G2.com.

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. Review collected by and hosted on G2.com.

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.

Mail delivery is reliable with the overwhelming majority of spam, malware, phishing links etc. automatically removed. Review collected by and hosted on G2.com.

The administrator UI is confusing and hasn't improved in many years. Review collected by and hosted on G2.com.

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. Review collected by and hosted on G2.com.

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. Review collected by and hosted on G2.com.
