Member Company Certifications
CREST Full Members consist of companies that have passed the rigorous Company Membership Application process, including agreeing to the CREST code of conduct, confirming their staff vetting procedures meet the CREST minimum requirements, agreeing to the CREST dispute arbitration process, have Professional Indemnity Insurance, have strong Security Assessment testing methodologies and have paid their subscription fees in full.
This table also provides guidance as to which organisations employ individuals that have undergone and passed the CREST Application Certification and / or CREST Infrastructure Certification professional qualifications, or have undertaken the entry level exams as a CREST Registered Tester (CRT).
Whilst CREST has made a reasonable effort to ensure the accuracy of this list you should not rely on this and you should verify the status of any individual member directly with the company concerned.
