How the verification model works (for buyers and carriers)
Certifications are held by individuals, never organizations. Org-level status below is a DERIVED rollup of named holders, the org claims nothing its holders do not hold. Issuer directories (GIAC, (ISC)², ISACA) list individual certificate holders with expiration dates, registry lookups resolve at the named-holder level and require no carrier data.
Your team's certifications are not yet on this page. When documented, buyers see them at the named-holder level, registry-verified with dates.
