Featured Reviews

Rizki Arya Indracahya - PeerSpot reviewer
Efficient integration and log monitoring enhances security operations
The central management needs improvement. The ease of use for updating and managing through the web console is difficult and lacks features. Integration with Mobile Device Management is not good, and controlling client update times can become problematic. If there is a network issue during an update, it can create junk files on the system, filling up disk space.
John Rallo - PeerSpot reviewer
Offers excellent visibility into vulnerabilities and the attack surface itself
Attack surface reduction and limiting attack surface vectors are valuable features. It's helpful to isolate specific devices and get super granular with the features they offer. The visibility into the attack surface is good. It gets highly granular. I don't work on that side, but the people who do tell me they get more visibility.
