Who we are
About Threshold
Independent physical security consultancy, based in the UK.
The approach
Physical security is easy to underestimate. The locks are on the doors, the cameras are running, and the access control system has a green light. But the question that matters is not whether the controls exist — it is whether they hold when tested.
Threshold Security was founded to answer that question honestly. We conduct controlled, authorised assessments of physical security posture: attempting the things an attacker would attempt, observing what happens, and reporting back clearly.
We are based in the UK and work nationwide. Our background spans physical security, cybersecurity, and the intersection of the two — because in practice, a failure in one almost always enables a failure in the other.
