CHECK Certification

The CHECK (CHecklist Evaluating Computers and Key security) scheme was established by CESG (the UK government's National Technical Authority for Information Assurance, now part of the National Cyber Security Centre) in 1997. It was created to provide a structured framework for conducting information technology security assessments and penetration testing within UK government and critical national infrastructure environments. The scheme was designed to ensure that individuals performing security testing on sensitive systems possessed verified skills and adhered to established standards and methodologies.

The CHECK certification is highly valued because it represents government-endorsed validation of a security professional's ability to conduct rigorous, methodical security assessments. Organizations handling sensitive government data or operating within critical national infrastructure sectors often require CHECK-certified testers to ensure compliance with UK security standards. The certification's importance stems from its strict vetting process, which includes security clearance requirements and demonstration of technical competency, making CHECK holders trusted to access and test sensitive systems where standard commercial certifications may not suffice.
