What GDPR means, and what it does not
"GDPR compliant" is a claim, not a certification. The verifiable facts are a public DPA, SCC usage, an EU representative, data residency options and a Data Privacy Framework listing.

Is Halcyon GDPR compliant?
There is no GDPR certification in general use. The verifiable facts are a public data processing agreement, standard contractual clauses, an EU representative and a Data Privacy Framework listing. See the legal artefacts and the DPF row on this page, each with its capture date.
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.
