The best thing about this product is its ability to simulate attacks against our network with ease. It's very easy to set up as well as use. I have been able to test my network for vulnerabilities in real time without having to go through the hassle of actual testing. Also, I can see what would happen if an attacker were to gain access to some sort of system or device within our environment. This has helped me identify areas of weakness in our network which needs to be addressed immediately! Nothing really! We've been using this software since we started working together with them back in 2015. They're always willing to help out when there are issues, they also respond quickly whenever questions arise.
