The Gray Man Theory involves the intentional act of behaving in an inconspicuous manner in order to avoid any unwanted attention. Both defensive and offensive security missions have the same objective, work the environment, work the problem and find a solution in an inconspicuous manner.

Industrial security solutions should strive to work in such a way as to not impede production, work in the background to protect a customers process from unintended behavior and of course protect their intellectual property.

Kwan Lee, Senior SYSTEMA Instructor talks about the Gray Man Theory in his Mastering FEAR video.   I recommend you watch the entire clip for an appreciation of the context but around 2 minute, 20 seconds of this short clip you will get the sense of what Kwan means as he speaks about the Gray Man Theory.

Bottom line, the Gray Man Theory is very applicable to the physical and cybersecurity arenas.   We felt it represents the undertone and foundation of successful security implementations. And that’s why we are called Gray Man Cyber.
