The ability for administrators to review a suspicious email before allowing it to be delivered to the users is such a great feature Review collected by and hosted on G2.com.

Mimecast Advanced Email Security does a good job of blocking phishing, malware, and impersonation attacks before they reach your inbox. The impersonation protection helps catch CEO fraud and spoofed emails. Setup is straightforward, and once it's running, it mostly takes care of itself. The admin dashboard has a lot of options, which can feel a bit overwhelming at first, but it gets easier to navigate over time. It’s not perfect—false positives happen now and then—but overall, it’s a solid option for keeping email threats in check. Review collected by and hosted on G2.com.
One downside is that it can be a bit aggressive with filtering, leading to false positives that require manual review. The admin dashboard, while powerful, isn’t the most intuitive and takes some time to get used to. Review collected by and hosted on G2.com.

Great UI and easy to navigate, quick learning curve. Review collected by and hosted on G2.com.
The setup is a bit annoying as we switched over, it seemed spam mail got through alot in the beginng and some emails that should get through did not. Review collected by and hosted on G2.com.
Nothing good to say. The service has not only been useless but counterproductive since the day we installed it. Review collected by and hosted on G2.com.
1) It blocks an incredible amount of easily identifiable legitimate emails including clients, from family members and - this is the best - emails from the company that installed it on our servers. 2) It has ignored every whitelist request we've given it & 3) customer support is non-existent. I honestly don't understand how anyone with business accountability can allow this software to exist in their organization (we are removing it). Review collected by and hosted on G2.com.
Among many, the most helpful features are impersonation, URL protection, Anti-Spoofing and Attachment control. The upside is the control and visibility of malicious/suspicious emails like spam, attachments and suspicious links. Review collected by and hosted on G2.com.
The least helpful is the limited log and mail retention period, which is 30 days by default. The downside which faces is that granular filtration doesn't function as expected. Review collected by and hosted on G2.com.
