How the Snubnose Assessor Alliance Works

The Snubnose Assessor Alliance is a partnership programme for Certification Bodies that deliver Defence Cyber Certification (DCC) assessments under DefStan 05-138. CBs run their assessments inside the Snubnose workspace, receive applicant referrals from Snubnose's supplier pipeline, and gain platform training and shared operational learnings from across the Alliance. No referral fees are paid, in line with ISO/IEC 17021-1 §5.2.3 impartiality requirements.
