One thing I have appreciated about Mimecast Advanced Email Security is how effectively it catches phishing and impersonation attempts it flags look-alike domains and spoofed sender names before they reach the inbox, often with a clear warning banner. The time of click URL protection is also a nice touch, since it re-checks links even after delivery, catching malicious sites that go live later. On the admin side, the dashboard gives good visibility into threat trends and blocked emails, which has been useful for our IT team.

It integrates smoothly with our existing email setup without much disruption. The one downside is that it occasionally flags legitimate emails as suspicious, so there's a bit of a learning curve in fine-tuning the filters, but overall it's been a reliable layer of protection.

Honestly my biggest complaint is the admin dashboard, it's kind of a lot to take in at first. Took me a while to figure out where everything was instead of just clicking around trying to find stuff. It connected fine with our Microsoft 365 setup, but a couple of the settings weren't as easy to line up as I thought they'd be. Sometimes a normal email gets delayed a few minutes because it's scanning it, which is annoying if you're waiting on something important.

It also flags emails as suspicious sometimes when there's nothing actually wrong with them, and it's not always clear why it did that. Support was fine when I reached out, but the onboarding kind of assumes you already know a bit about email security, so it wasn't super beginner friendly at first. And it's on the pricier side compared to other options, so that's something to think about if budget is tight. Review collected by and hosted on G2.com.

Honestly, it's how much it stops before I ever see it. Phishing and spoofed emails just don't make it through, and the link and attachment scanning has caught stuff that would've slipped past us otherwise. The admin side is simple too, easy to pull logs or release something from quarantine without digging around. Review collected by and hosted on G2.com.

The false positives are the main annoyance. Legit emails end up in quarantine more often than I'd like, so there's a bit of babysitting involved. The interface also feels dated in spots, and finding the right setting sometimes takes longer than it should. Nothing dealbreaking, just friction. Review collected by and hosted on G2.com.

The administrative user interface feels somewhat dated and can be complex to navigate at first.

I really appreciate the overall depth of email protection that Mimecast Advanced Email Security provides, particularly in handling phishing, malicious URLs, attachments, and impersonation threats. The level of control available for security teams is impressive, and the policy controls are useful in configuring different customer requirements. I find the reporting and visibility features very helpful during deployment, as they allow us to understand what is being blocked and fine-tune policies. The administration is relatively straightforward once the initial configuration is set up properly, which I find quite beneficial. Review collected by and hosted on G2.com.

The initial setup can take some time, especially in complex email environments or when replacing an existing email security solution. Some policy tuning is also needed after deployment to reduce false positives. The reporting interface could be a little simpler and more intuitive for quick analysis.

I really appreciate how Mimecast Advanced Email Security filters phishing, spam, and suspicious links, making it incredibly useful for our organization where each user gets about 100 to 200 emails daily. Having emails quarantined gives me great visibility and control to investigate them without bothering users. I also like the default policies and the ability to edit them extensively, which is quite helpful from an admin perspective. The quarantine management is excellent; I can easily check and decide on email releases. I love that it provides comprehensive visibility into email activities, simplifying investigations of suspicious messages. The control over email security is great for a small IT team like ours as it requires little ongoing attention once policies are set. Also, the extra information it offers beyond basic email filtering makes it easier to trace and check specific emails. Review collected by and hosted on G2.com.

I think one thing that could be improved is the amount of time it takes to understand why an email was blocked. Sometimes we have to dig into the message details and policies to figure out exactly what triggered it. The admin interface is also a little busy when you're using it for the first time. Once you're familiar with it, it's fine, but some settings could be easier to find, especially when checking extra activity logs in email security. It's a bit confusing at first, but once you get used to the product, it really helps because it provides a lot of information. Review collected by and hosted on G2.com.

I was working in one project in my current company it does a good job of detecting and blocking phishing attempts, malicious links, and suspicious emails before they reach the inbox. The setup and onboarding were fairly straightforward, and there are plenty of resources available if you need help understanding a feature or configuring a policy.

The main thing I would improve is the user interface. There are quite a few settings and options, and it can take some time to find exactly what you need or understand how certain policies work. Some parts of the administration could be more intuitive and easier to navigate. Performance has generally been good, but the overall experience could be simpler for administrators.

The threat detection is reliable it catches phishing attempts and spoofed sender emails before they reach the inbox, which matters a lot in a university setting where accounts are frequently targeted. I also found the [impersonation protection / attachment scanning] useful for flagging suspicious messages that looked like they came from faculty or IT. Overall it gave our lab more confidence in email security without requiring constant manual monitoring. Review collected by and hosted on G2.com.

Occasionally there were false positives a few legitimate emails, like ones from academic mailing lists or newsletters, got flagged or quarantined and needed to be manually released.
