Mimecast is mandatory to stop the troves of spam and phishing sent to emails scraped off our website. Review collected by and hosted on G2.com.

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. Review collected by and hosted on G2.com.

What we like best about Mimecast Advanced Email Security is its comprehensive protection against a wide range of email threats, including phishing, malware, and spam.

The user-friendly interface and easy integration with Office 365 made it simple to manage and deploy, and the customizable policies allowed us to tailor the security settings to our specific needs.

The Customer Support is very knowledgable and gets back to us in a timely manner. Review collected by and hosted on G2.com.

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 Review collected by and hosted on G2.com.

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. Review collected by and hosted on G2.com.

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! Review collected by and hosted on G2.com.

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.

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.

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