“I explain the future of security before the market catches up.”

Two decades in the trenches.
Zero Trust before it was a buzzword.
Cloud when everyone said it wouldn't scale.
Still here.

THE LIGHTBOARD IS THE WEAPON

Brian doesn't just explain security. He draws the architecture, exposes the assumptions, and makes complex ideas click — live, on glass, in real time.

The lightboard format strips away everything except the idea. No slides. No hand-waving. Just glass, a marker, and someone who actually knows what he's talking about.

SECURITY IS NOT A CHECKBOX
