MimeCast Email Security Reviews in January 2025: User Ratings, Pros & Cons

"Complicated, but worth it."

What do you like best? The service is very thorough. So thorough that sometimes it frustrates users who want or need simple attachments, but Mimecast knows the potential for those attachments to be malicious, so it blocks them. Personally I'd rather be safe than sorry. What do you dislike? It is a very complicated service to use. VERY. If I'm modifying a rule, or adding some exlusion somewhere, I almost always have to have tech support help me out. Or especially on a Discovery case if we're ...

"An excellent Email Security and Threat Protection solution."

What do you like best? The granularity with which we can manage users, groups of users and how they interact with the system by setting up notifications of quarantines, journals of held emails or even just tagging on email delivered to their mailbox depending on their level of sophistication or work function and needs. We also appreciate the ability to watch for outgoing PII or PHI in order to place holds on potential information leaving our environment. This is only a little bit of what ...

"Effective but tough to administer"

What do you like best? When well tuned Mimecast blocks an awful lot of problem emails, to the point where I don't worry much anymore about spam and phishing. What do you dislike? The Mimecast administration web pages are slow and poorly organized. What should be simple adjustments often require many steps, and the interface is curiously fragmented. What problems are you solving with the product? What benefits have you realized? The number one problem I had to solve was stopping phishing ...

"Mimecast Email Protection is robust tool and has saved our company time and energy."

What do you like best? What I like best about Mimecast Email Protection is the granularity which you can apply policies for different types of email. On top of the normal spam scoring feature we also leverage the Impersonation Protection, Attachment Protection and Anti Spoofing Protection to guard against malicious email attacks. What do you dislike? One of our biggest frustration is having multiple policies set up in the Impersonation Protection that apply to specific executive users but ...

"Mimecast does a lot of things great with a few minor annoyances"

What do you like best? I like how Mimecast gives you a lot of control over various policies and definitions. What do you dislike? There's a few things that can be annoying... For example, the Greylisting feature requires previously unknown senders to retry messages to verify RFC compliance. A lot of OTP servers are not RFC compliant apparently which causes those messages to be rejected. These emails come from randomized email addresses, so you're unable to add them to you permitted senders ...

"Mimecast Email Security with Threat Protection Review"

What do you like best? Portfolio is comprehensive and provides strong security for my users. As an admin the setup is easy and allows for lots of customizations and integrations. What do you dislike? Support can be slow to respond and the only way to get support quickly is to call in. What problems are you solving with the product? What benefits have you realized? better protection on inbound and outbound email for malware and spam. Mimecast does a very good job of keeping spam from ...

"Reliable and secure"

What do you like best? To my knowledge, we've never had an outage in the two years we've been using Mimecast Email Security. Most of the email attacks we've encountered, Mimecast has had a solution available; i.e. Impersonation Protect. What do you dislike? Most of my time I spend in Mimecast is to troubleshoot email delivery issues. I find it difficult to almost impossible to determine what module blocked a particular message. Similarly, while it has improved somewhat, I still have to use ...

"Pretty effective. Not sure if worth the admin overhead."

What do you like best? Definitely is a solid wall against unwanted and dangerous email. Dashboards are clear and easy to see data What do you dislike? Administration is very clunky, unclear. Simple modifications to policy or exceptions require much more time and effort than competitors. As an experienced SysAdmin (though new to this tool), I needed 2x support calls to solve a firedrill. What problems are you solving with the product? What benefits have you realized? Almost zero spam hitting ...

"Great Product for Phishing Scams and Email Threats - YS at OCBF"

What do you like best? I like that you can get tips about email threats like Phishing. The Administrator console has so many features that are so easy to understand. The messaging feature makes it easy to find any particular email that you are looking for, searching by the hour, day, month or a customized date range. It is just organized very well. What do you dislike? The search feature sometimes takes a couple of tries to find what you are looking for. I usually can find a great document ...

"I've been a customer for a few years and would highly recommend the product."

What do you like best? Alerting mechanism and peace of mind the product will add a layer of security to our organization. What do you dislike? Wish they had a way to remove phishing emails by subject and not by ID alone. What problems are you solving with the product? What benefits have you realized? primarily phishing emails.
