The public register of all systems, products, and implementations currently holding valid ARDS certification. Published and maintained by AxiomOrdo. Updated in real time as certifications are issued, renewed, and revoked.
The ARDS Certified Directory is the authoritative public record of ARDS certification. Regulators, enterprise procurement teams, and system integrators use this directory to verify claims made by software vendors.
Each entry lists the certified product, the holding organisation, certification level, applicable domain packs, certification date, and expiry date. Each entry links to the machine-readable Certification Token.
Every entry has a permanent verification URL. Any party can call the verification endpoint to confirm a certificate's current status — valid, expired, or revoked — without contacting AxiomOrdo.
Listing in the directory is automatic upon successful certification at L3 or above. L1–L2 are self-declared and do not appear in the directory. Apply for certification →
The ARDS Certified Directory is open and accepting its first entries. Be among the first certified products — founding partners receive premier placement, co-marketing support, and the lowest certification fees we will ever offer.
