Penetration Testing
Delivered by specialists with backgrounds in UK Special Forces, government, and defence, ensuring the highest professional standards.
Our Red Team operations, often referred to as penetration testing, are designed to rigorously assess the physical, technical, and human security measures protecting your organisation. These operations simulate real-world threats in a controlled, ethical, and legally compliant manner to expose vulnerabilities that could be exploited by hostile actors.
Pen Testing Service
S2K's penetration testing services are led by former UK Special Forces and Home Office surveillance professionals with extensive experience in hostile environment operations, infiltration techniques, and counter-intelligence methodologies. Every engagement is bespoke, developed in collaboration with the client to define clear objectives, boundaries, and success criteria.
Operations may include covert reconnaissance, lock bypass, tailgating, impersonation, and secure area breaches, all conducted with a strict chain of custody and full debriefing protocols.
We test and challenge:
Physical security (access control, alarm systems, perimeter integrity)
Personnel awareness and insider threat resilience
Procedural vulnerabilities and access routines
Digital hygiene, social engineering susceptibility, and information leakage
At S2K, we don’t offer generic off-the-shelf audits. We offer high-fidelity red team simulations rooted in real operational experience.
The result: meaningful, actionable feedback that helps organisations strengthen their defences before someone with intent tests them for real. Our track record includes successful red team deployments across government, corporate, and critical infrastructure sectors.
