Physical Security Audits · UK
Testing your defences before someone else does.
Threshold Security conducts independent physical security audits for businesses across the UK. We find the gaps — locks, access control, personnel, process — and tell you how to close them.
What we do
End-to-end physical security testing
Every engagement is scoped to your environment. No templates, no box-ticking — real-world testing that reflects real-world threats.
Physical Penetration Testing
Controlled attempts to breach your physical perimeter — fences, doors, access control, reception — before a real attacker does.
Social Engineering Assessment
Testing how staff respond to tailgating, impersonation, and pretexting scenarios that bypass technical controls entirely.
Security Audit & Review
A structured review of your physical security posture: CCTV coverage, lock grades, access control policy, and guard protocols.
Remediation Roadmap
Clear, prioritised recommendations your team can act on — no jargon, no vendor bias, just practical steps to close the gaps.
Why Threshold
An attacker's mindset,
a consultant's report.
Physical security failures are rarely about the locks. They are about the habits, the exceptions, the “we've always done it that way.” We look at your site the way an opportunist or targeted attacker would — and document exactly what we find.
Deliverables are written for decision-makers and operational teams alike: risk-ranked findings, photographic evidence, and a clear remediation path.
