About

What the TrustMarc Initiative is.

The TrustMarc Initiative is an open effort to make trust in content visible, verifiable, and portable. The trust infrastructure behind it is operated by Coherent Digital, under the guidance of an independent Standards Council. Anyone evaluating content can then see who stands behind it, and why.

What it is

A neutral overlay, not a gatekeeper.

TrustMarc doesn’t replace anyone’s trust signals or decide what’s true — it coordinates what already exists. The initiative is built at arm’s length from any single vendor: Coherent Digital delivers and maintains the infrastructure on the community’s behalf, while the standards are guided independently.

Governance

Governed by an independent process.

TrustMarcs don’t decide what’s true. They make transparent who evaluated content, against what standards, and why it can be trusted.

TrustMarcs are issued against criteria reviewed through an open process guided by the TrustMarc Standards Council. The Council doesn’t assess individual items — it reviews and approves the frameworks and criteria that Issuers use, keeping them transparent, consistent, and publicly documented.

Organizations can submit their own review, endorsement, preservation, or assessment frameworks for approval. Those without established criteria can adopt the openly licensed (CC BY) TrustMarc Recommended Criteria.

Every approved framework, Issuer, and certificate is public and verifiable — so standards are governed independently while trusted organizations evaluate content within their own expertise.

Open by design

You keep what’s yours.

When you issue TrustMarcs, you own them. Members hold — or share — ownership of their trust data and can use it however they like. The opposite of lock-in.
