Featured Reviews

MOHAN SUKUMAR - PeerSpot reviewer
Secure email management improves through advanced filtering and dynamic virus scanning
Fortinet FortiMail offers capabilities like settings for mail delivery, mail filtering, spam controls, and email bursting prevention. It also allows for email forwarding, dynamic filtering, and scanning based on virus signatures. I can set varying levels of security. The tool is flexible and provides essential features for mail security and management.
Amber Worth - PeerSpot reviewer
Retrieves data from quarantines and easy to read logs with robust security features
Some of the searchability when looking for specifics in Exchange logs is tedious. Although eventually the information is located, it can be difficult if detailed information is lacking. Improving the search process by allowing searches with different types of parameters and facilitating searches within emails would be advantageous. Simplifying interfaces would also be appreciated.
