This is wrong

What is not public

  • The Visa registry lists the assessor and the date the validation runs through, not the services in scope of the attestation of compliance.
What PCI DSS means, and what it does not

Only a registry listing (Visa Global Registry, Mastercard SDP) or an AOC letter is strong evidence. In the Visa registry only rows validated as PCI DSS with a validation date count; Third Party Agent registrations are not PCI evidence.

Questions buyers ask

Is Sierra Technologies PCI DSS compliant?

Sierra Technologies is listed as a PCI DSS validated service provider, assessed by SISA, valid through 31 Jan 2027, as of 2 Nov 2026.

How does CertReports verify this?

Every state carries a capture date, a source and a snapshot link. Registry rows come from the official registry data; vendor statements come from the vendor’s own page or trust centre; nothing is inferred. Vendors can dispute any row and corrections ship within two business days.
