The Intro to Vulnerability Assessment course (#CYB801) is one I'd recommend for any member of an IT team wanting to start on the path of improved security. It's an intro course but covered more than enough to get familiar with the basics of the security assessment landscape. It was time well spent.
The exercise was so successful that we have entered into a committed partnership with TEEX expanding their role in our cyber individual contributor, managerial and director-level training + policy consultation. We would indeed recommend TEEX without hesitation or caveat.
They provided professional guidance for a tense and difficult situation. It immediately gave us a clear direction. The speed of their response was amazing. There were the specialists we needed, in our office, the next morning. I was expecting a response in days, but they were reviewing logs within hours of my first contact to TEEX.
