Alcus Erasmus | Head of Cyber Security Engineering, MAG

Defend not only provides an additional layer of defense but also supplements our security awareness training. Defend’s clickable banners allow employees to … continuously develop their cybersecurity awareness.

Kevin Orritt | Cyber Security Manager, GMMH

We’re particularly impressed with the administration capabilities. I used to spend hours configuring rules and monitoring quarantines, but this is no longer the case. The admin page gives us the ability to have all the threat intelligence we need in one place, quickly and simply, as well as remediation capabilities – ultimately allowing better peace of mind and time back in my day.
