FAQ
What does CREST CRT mean on this index?
Companies with current, scoped evidence for CREST CRT. A certificate, report or authorization may cover a particular legal entity, service or period. Practitioner credentials belong to people, not the company. We review linked documentation; we do not independently audit it.
Is the order paid?
No. Companies are alphabetical by default. You can sort by team size or date added. Promoted shelves are labeled and separate.
How do I get listed under CREST CRT?
Provide a public source identifying the covered organization, service or team, its scope, a check date and any stated expiry. A checkbox alone does not qualify. Evidence needs a new documentation check after 180 days and stops qualifying sooner if it expires. Payment does not establish a credential.
Why is a staff exam on a company directory?
Buyers shortlist pentest and training firms by who sits on the engagement. OSCP and GPEN are company filters here, not a people directory.
