Physical Penetration Testing Providers
Physical penetration testing evaluates the effectiveness of an organisation's physical security controls by attempting to gain unauthorised access to buildings, secure areas, and sensitive assets. Testers use techniques including lock picking, badge cloning, tailgating, social engineering of reception staff, bypassing access control systems, and exploiting weaknesses in physical barriers.
Physical pen testing assesses entry points, CCTV coverage and monitoring, alarm systems, guard procedures, visitor management processes, and the security of sensitive areas such as server rooms and executive offices.
This type of testing is critical for organisations that rely on physical security to protect data centres, critical infrastructure, research facilities, and high-value assets. Physical pen testing is often combined with social engineering testing for a comprehensive assessment of human and physical security controls. It is required or recommended by several compliance frameworks and is particularly relevant for organisations in defence, financial services, healthcare, and government sectors where physical access could lead to significant data breaches or operational disruption.
