Email Security Engineer at Logic Infosecurity

Mimecast Email Security includes the best gateway solution across all Cisco, Trend Micro, and other solutions. For customers who want a traditional gateway, we suggest using Mimecast Email Security. For customers who want the advanced solution, we suggest Check Point for those features.

Mimecast Email Security's anti-phishing features are good and perform as expected.

Mimecast Email Security is a good solution because our customers haven't reported any phishing emails being delivered. It performs effectively as a traditional gateway solution. We haven't received any complaints regarding this solution.

Filtering from threats before emails are reached mailboxes.
URL protection and sandboxing. Potentially dangerous links are open in Sandbox rather than in user's web browser further helping with potential threats.

In terms of efficacy, Proofpoint is better than Mimecast, though it's a little difficult to manage. A distinct advantage of Mimecast is its ability to block phishing and impostor attacks, which are significant threats currently. Security is a major feature where email security tools like Mimecast have delivered value by identifying and preventing phishing emails.

Mimecast Email Security serves as the main email security tool in our organization. It acts as the email gateway, scanning emails before delivery to end users. One of the most useful features is the threat remediation module, which can be used to remove malicious emails that may have been delivered or manually remove them. We benefit from visibility into emails being sent or delivered, and we can analyze issues like incorrect DMARC configuration by third parties. This provides a good understanding of user interactions with external parties. View full review »

Due to our specialized use case, that HIPAA dictionary really comes in handy due to the fact that you just can't find that in a lot of products out there.

It can scale.

We have 99-year retention and that has enabled us to get down to a 60-day retention policy on our emails, so that's pretty cool. In the current environment that the world is in, everyone is trying to hack everyone else, so Project+ definitely helps a lot there.

What I like about the integration is that it is directly into Microsoft 365, users can use their Microsoft 365 credentials to log into the portal and access their mail.

It does have integrations, and there is an app that can be added to Outlook to allow them to do what they need to do. 

While some of the setups are probably not as user-friendly as some of the other platforms, there is a lot of customization that you can do to the platform to help you pull up a lot of stuff that shouldn't be going into users' mailboxes.

I believe the world is going through a crazy period right now, and everyone is attempting to penetrate different systems as quickly as possible and change their ways of doing things. 

I have always found Mimecast to be very responsive; for example, if we see something come through, they address it and it helps to sort out the issues. Overall, I'm pleased with them. I think I just look at what's out there every year during renewal time to see if we're still on the best platform or if we should consider migrating to something else.

It has great reporting, and we can see what's going on.

I am pleased with the features we have at the moment and everything it does; it's only one piece of the puzzle for our environment, but I'm pleased with how it detects things and some of the functionality that we have had to set up due to the complexity of our business and security. I'm pleased with everything. I don't have anything specific in mind that I'd be looking for.

We are monitoring emails that come from outside the organization. Some impersonation policies are in place, and we are tracking five different types of impersonation policies. These policies include external IP addresses, external users, reply-to mismatches, default inbound attachments, and VIP impersonation cases.

The URL protection feature is valuable because it communicates all attachment-related activity and provides access to view the content of the message directly. Additionally, it can directly provide you with the content of emails if you have been granted access.

The security on offer is very good. It's great at preventing users from accessing malicious sites or email.

The filtering features are excellent. It allows you to any links an email might have. For example, when a user receives an email with a link, Mimecast takes that link and scans it, checking for any malicious content. If it's okay, then it passes on the email to the user. If it's not okay, or it's not sure about the content of the link, it then sends a notification to the user. It helps users to look at the user to see if it is a trusted source or not, and to decide if they want to open it or not.

The stability is very good.

The initial setup is very straightforward.

The technical support is excellent.

The two most valuable features are anti-spam and Large File Send. I know a lot of people that have Mimecast in front of Office 365 because it's a pretty good firewall in front of your email.

The Large File Send feature comes in handy when you have to send fairly large attachments.

They provide training classes online, where you can review with an instructor.

The piece that is most valuable from the Mimecast standpoint will be the sandboxing feature. They have a process where whenever they receive an email with an attachment, they process the attachment through a sandbox. Depending on your configuration, this is a customer-specific configuration, you can tell it to do a bunch of things. You can block the attachment, you can create a safe version of the attachment, or you can tell it to let it go or put it in a help queue for either user moderator or administrator review.
