CREST Marketplace

Pentesys is a UK cybersecurity company, operating worldwide, helping organisations understand, validate and reduce their cyber exposure.
We combine AI-driven security testing with experienced human expertise to give organisations clearer visibility of risk and the evidence needed to take action.
The Pentesys Portal connects four core capabilities in one environment: Foundation for Cyber Essentials readiness and assurance; Expose for continuous external attack surface discovery and monitoring; Validate for penetration testing and continuous security validation; and Adversary for red teaming and real-world attack simulation.
Rather than relying solely on point-in-time assessments, Pentesys helps organisations continuously discover what is exposed, prove what can actually be exploited, prioritise remediation and verify that issues have been resolved.
AI-driven coverage. Human-verified security.
