The big idea: you can only trust what you've tested.
After over a decade spent defending and attacking enterprises, this is my core conclusion.
Having worked with companies ranging from five ambitious engineers in a cowork space to Fortune 50 giants, I know that the best security posture is demonstrably resilient.
I've made my career at high-performing firms helping people understand the real nature of threats and defend against them with practical measures.
Until you've tested it, you don't know what an attacker does after bypassing your EDR software.
You don't know how far they can get using a zero-day exploit with no patch against your firewalls.
That distance — between what a defense is assumed to do and what it actually does under pressure — is what I write about.
