Robert Melendez - PeerSpot reviewer
Vice President Information Technology at Makeready
Enhances email security and has a very simple and easy-to-use UI
Spam protection is the most valuable feature. We have implemented the tool to enhance our email security. It helps prevent phishing attacks. The anomaly detection capabilities are baked into the security platform. The product integrates wonderfully with Microsoft 365. It's built right on a cloud platform and works almost natively. The solution has a very simple and easy-to-use UI. The tool appears extremely powerful and has a good solid feature set. It catches things that are bad for my environment. The user interface is good the way it is. If the solution continues down that path, I see no problems with the way it is going. It feels like a mature product.

Block significant threats with enhanced phishing prevention
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.
