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. Review collected by and hosted on G2.com.

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. Review collected by and hosted on G2.com.

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. Review collected by and hosted on G2.com.

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.

Once configured the system works well and does it's job without any further intervention. There are a good number of features and the archiving system works well Review collected by and hosted on G2.com.

There still seem to be a number of bugs in the system, such as SAML errors when logging in. This happens with a number of our admin users. Initial setup was quite complicated Review collected by and hosted on G2.com.

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 assesed is really important. Also, the great range of security features make me confortable that Mimecast is protecting us. Review collected by and hosted on G2.com.

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. Review collected by and hosted on G2.com.

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 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.
