About me and three security POCs
Some examples of my recent work. Each is about a minute.
Introduction
Who I am and how I work
30+ years building enterprise infrastructure with security built in.
poc-gates
A policy gate that blocks bad infrastructure before it applies
Every Terraform plan graded by a deterministic rulebook plus an AI judge. One deny anywhere, and nothing is created. Fail-closed.
poc-defense
A runtime tripwire that auto-contains hostile changes
Watches live cloud activity and, on a hard-deny, locks the resource group down. Fail-safe.
poc-purple
An autonomous purple team that hardens its own defenses
Attacks, measures what got through, hardens the policy on its own, then re-attacks to prove the fix.
