Why is the trust layer free?

Standards need adoption

Like TLS/HTTPS, agent trust only works when it's everywhere. Paywalling identity verification would fragment the ecosystem.

Compliance is inevitable

When your agents handle production traffic, you'll need audit trails. Not because we require it—because your auditors will.

We sell assurance, not access

Free users get the same cryptographic guarantees. Enterprise pays for retention, integration, and support—not capability.

Common Questions

What are the limits on the Public Trust Layer?

The Public Trust Layer is designed for development, testing, and early production use. There is no trial period—this is not a limited-time offer.

When trust becomes a compliance or availability concern—meaning you need extended audit retention, SIEM integration, or SLA guarantees—Enterprise Assurance applies.

We will never surprise you with a paywall. If your usage approaches enterprise thresholds, we'll reach out to discuss your needs.

Is domain verification (did:web) really free?

Yes. Domain verification is a trust primitive, not a premium feature. Free users can verify their domain to anchor agent identity. Enterprise customers get additional domains and organizational verification.

When do I need Enterprise Assurance?

It becomes clear when trust moves from an engineering concern to a business risk. Common triggers:

  • • Your compliance team asks for 90+ day audit logs
  • • You need to export events to your SIEM
  • • You require SSO/SAML for team access
  • • You want VPC or on-premises deployment
  • • You need an SLA for support

Can I self-host?

The CLI, Guard, and SDK are open source—run them anywhere. The hosted registry is a managed service. Enterprise customers can deploy the full stack in their VPC or on-premises.

How is Enterprise Assurance priced?

Based on your deployment requirements, not identity counts. We discuss your audit retention needs, integration complexity, and support requirements to build a custom quote. Typical engagements start in the mid-five figures annually.
