Void Security

Last updated 2026-10-29 · 1 of 3 retainers available

A one-person security practice run by a director-level operator. Red team leadership, AI systems, and industrial networks.

Capacity-limited by design: three retainers, no team of forty, no 24/7 rota. If you need a firm with a rota, I will tell you which one to call.

I do three things: I take ownership of a red team programme that has lost its owner, I attack AI systems before someone else does, and I tell industrial companies what on their plant floor is reachable from the corporate network.

The engagement model is fractional because that is what fits an organisation that does not need a full-time head, cannot hire one, and does need someone accountable for the decisions.

What we do not sell

This list does more commercial work than anything above it.

On physical security: licensing is issued per jurisdiction, and a firm that claims coverage it does not hold is the exact red flag you should run from. If your requirement is guards, sites and hardware, this is not the supplier.

The Security Guild

People and firms I have worked with, and trust and respect enough to recommend point-blank. No commission moves in either direction — the Guild is about honest recommendations. Listed October 2026.

Scan us

This site is scanned by robots constantly and by me on a schedule. The edge posture is published. The monthly probe summary stopped being a promise: One of Them Was Lying, dated 2026-10-28, thirty days of my own logs classified by family, tool and client class, including the finding where my own server was the one lying. Neither is curated.

Scope something

One email is enough: what changed, who is asking (board, customer, insurer), your sector, and your deadline. If it is a fit I answer with a scope and a price; if it is not, I answer with the name of someone better placed.
