I spoke with my friend who is in the security consulting business. While he does not know Brent Brown, he has mutual clients with them, and has a generally favorable impression of them based on his conversations with the mutual clients. In short, Brent Brown is “real” and almost certainly credible, is his take on this.
My friend designs security and access control systems for commercial and institutional buildings, and Chesley Brown primarily provides security guard services, just to explain their industry connections.
Thanks for the confirmation.
