I find the way in before someone else does.

Adversarial security, IT, and custom software from one engineer who works every layer — network architecture to endpoint hardening to the tools that run on top.

"A black-box view of your organization. I don't follow a checklist — I follow the logic of an adversary, then show you exactly how to stop it."

Adversarial Assessments

A full-lifecycle, black-box engagement run the way a real adversary would — reconnaissance through action-on-objectives, then graded findings and a re-test. Open or blind.
