Featured Reviews

Luis-Brown - PeerSpot reviewer
Allows for easy reporting of problems, valuable anti-phishing, and anti-malware support
Microsoft Defender for Office 365 lacks proactivity in assisting us with preparing for potential threats before they occur. While they employ a substantial amount of threat intelligence to preemptively prevent incidents, their effectiveness diminishes when it comes to delivering proactive threat intelligence alerts from Microsoft. Their focus primarily revolves around managing the internal environment. On the other hand, my other vendor, Check Point, along with my membership in MS-ISAC, supplements me with this type of information. The phishing and spam filters could use some improvement. It is adequate, but it doesn't match the quality of Proofpoint or Mimecast. However, it comes close in effectiveness. Plus, if we're obtaining it for free, investing in the other products seems impractical.
John Zupancic - PeerSpot reviewer
Pricing that is competitive, excellent technical support, and email security
They do a better job of distinguishing between what's real and what's not than most of the other solutions we've tried. They are very easy to use. We don't have as many problems with email security. They have some areas that could be improved. For example, we also use Zix email Encryption for email encryption, which was clunky and could be improved, but the email security itself has been excellent.
Frank Rawson - PeerSpot reviewer
It gives clients peace of mind and helps them educate their users about threats
A few years ago, our team found the implementation to be somewhat challenging. It has gotten easier as we've grown more experienced. The difficulty depends on the expertise of the person doing it. I don't work with Mimecast every day, so it might be more difficult for me than it is for one of my techs who regularly does Mimecast implementations. It requires some specific in-depth product knowledge and an understanding of email solutions. The deployment time varies. In South Africa, it depends on who you use to deploy it. If you use one of Mimecast's local partners, it can take up to two weeks because of their process. However, it's only about four to eight hours of work. After deployment, there isn't much maintenance aside from supporting and educating your customers. Users require constant education on how to use the Mimecast client and release an email that has been blocked.
