Physical Security Assessment

A rigorous and strategic evaluation of your facility’s physical defences that are designed to identify vulnerabilities, prioritise mitigation, and strengthen resilience across people, processes and place.

What is a Physical Security Assessment?

A physical security assessment is a structured review conducted by experienced specialists who examine the full spectrum of your security landscape. This includes:

Site visits to verify the condition of physical infrastructure: fencing, doors, glazing, locking mechanisms, lighting, CCTV coverage, barriers, and more.
Evaluation of access control: both pedestrian and vehicular, including ingress/egress points, vulnerable perimeter zones, and potential blind spots.
Review of operational practices and procedures: such as visitor management, key-control, patrol schedules, contractor management and incident response readiness.
Assessment of culture, awareness and behaviours: how staff, contractors and visitors interact with the site environment and how security is embedded in day-to-day operations.
Gap analysis and risk-based prioritisation: aligning findings against your risk profile, business impact, regulatory obligations and industry best practice.

Key Benefits – Why Commission a Physical Security Assessment?

Relying solely on alarms, access control cards or CCTV is no longer sufficient. This assessment will enable you to evaluate how your built environment, operational practices, systems and culture interconnect. It will also show you how each may be exposing you to risk.

Reveal hidden vulnerabilities: You may have systems in place, but a holistic review will expose how they integrate (or don’t) and where cracks remain in your defence.
Cost-efficient prioritisation: Not all risks are equal. A properly scoped assessment helps you apply budget and resource where they make the greatest difference.
Proactive rather than reactive: By identifying issues early you avoid being forced into costly remediation after an incident.
Create a robust security posture: Align environment, technology, processes and people for resilience that supports your strategic objectives.
Demonstrate due diligence: In the face of regulatory or insurance scrutiny, a formal assessment shows you are seriously managing physical security.
