Featured Reviews

Nasseer Qureshi - PeerSpot reviewer
Email security effectively detects a wide range of threats and improves productivity
Since we have been using Check Point Harmony Email & Collaboration for a year, we haven't encountered significant challenges. However, it would be beneficial if it could support other email security services beyond Microsoft and Google. Integration with other platforms would enhance its appeal since the features are commendable. While the analytics are commendable, they don't provide deep dive insights. They show the overall counts of malware, phishing, and business compromise emails, but there isn't a robust ability to dive deeper into those categories to see specifics. Analytics should allow us to explore which users received malware emails the most or trends among departments. Currently, we have to sift through manually, which is not ideal. A more profound analytical capability would elevate the tool to become the complete email security solution for any user.
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.
