Our Cyber Security Incident Response (CSIR) is approved by CREST, an international not-for-profit accreditation and certification membership body that represents the global cyber security industry. Worldwide, only a small number of cyber security providers have achieved this accreditation – which is fully endorsed by GCHQ and CPNI – highlighting Quorum Cyber’s commitment to continuous improvement of standards and quality of service.
