TET CERTIFICATES AND SEALS

Public verification signals for European technology trust.

TET seals turn private evidence review into clear public certificate metadata. Buyers see status, scope, validity, and covered modules without receiving private evidence, cap tables, or reviewer notes.

PRODUCT

A seal is the public signal, not the private evidence room.

Each TET seal is backed by a protected application record, module evidence, automated checks where appropriate, and reviewer decisions. The public certificate page shows only safe metadata so buyers can verify status without accessing sensitive company material.

Public verification

Every seal resolves to a current certificate record.

The public record gives buyers a canonical place to check the certified legal entity, certificate status, validity, standard version, and scope. Private evidence and reviewer deliberation remain protected.

Inspect the TET audit catalogue for a concise view of the modules, evidence categories, and review logic behind the seals.

COMPOSITE SEAL

Composite verification is derived from active certificates.

The Composite Verified Stack is granted when a company already holds enough qualifying active certificates. It is designed as a buyer-friendly summary signal, not as a separate evidence-heavy module.

Requires at least three qualifying active TET certificates.
One of the three certificates has to be "Operated in Europe"
Underlying certificates must be valid and not suspended, revoked, or expired.
Composite status changes when the underlying certificate set changes.
FOR BUYERS

Seals make vendor claims easier to verify without exposing private evidence.

Procurement, legal, security, and public-sector teams can check certificate status through a public verification URL or badge while the sensitive review material remains private.
