The assurance arm of the group. Test it, certify it, prove it.
CRIBB Cyber Security is a UK government-backed Certification Body for Cyber Essentials, Cyber Essentials Plus and IASME Cyber Assurance, and an accredited DCC Level 0 Certification Body. Penetration testing, vulnerability scanning, data protection and incident response, delivered by people who assess these standards for a living.

Our story
Founded in Hertfordshire in 2016, CRIBB set out to make credible cyber assurance accessible to organisations that don't have a security department: fire and rescue services, charities, law firms, manufacturers and the suppliers of defence primes.
Every client CRIBB has guided through certification has achieved it. As part of the Clipeum group, CRIBB is the independent proof behind everything else we do: we run your IT, defend it around the clock, and CRIBB certifies that it works.
