Research-Sourced (starting point)

Documented from public research, firm website, and cited public pages. Claims are labeled as claims. This is where every firm starts — including the ones now at the top.

Some of your evidence is here. More documentation strengthens how buyers rank you against firms with similar capabilities. Documenting them is free: no cost, no pay-for-rank, and a partial submission is fine.

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.
