Platform

One infrastructure. Every governed exchange.

Bifrost combines organizational trust, policy-based authorization, evidence governance, and cryptographic verification in a single architecture.

The same core trust mechanisms apply whether the exchange concerns a security assessment, supplier qualification, business approval, audit evidence, or an autonomous agent request.

Organizational Trust

  • Organizational identity and trust domains
  • Agent authentication
  • Identity assurance: self-asserted, domain-verified, IdP-verified
  • Accountable principals
  • Signing keys and verification, including customer-held roots

Delegated Authority

  • Scoped agent permissions
  • Delegation chains, up to three levels, each narrowing its parent
  • Purpose and parameter limits
  • Expiration and revocation
  • Counterparty authorization

Policy Enforcement

  • Cedar authorization decisions
  • Governed access, applied before retrieval
  • Evidence disclosure controls by tier and agreement
  • Refusal and escalation to a person
  • Tenant isolation and a per-tenant kill switch

Evidence Intelligence

  • Evidence management and connector imports
  • Version and freshness controls
  • Evidence-backed answers with citations
  • Citation checking against the exact excerpt
  • Source-conflict detection that refuses contradictory answers

Verifiable Records

  • Signed answer receipts
  • Signed review packets
  • Signed action decisions
  • Acceptance and execution-report records
  • Independent verification against an append-only transparency log

Interoperability

  • MCP
  • A2A v1.0
  • OAuth 2.1 and DPoP
  • OpenID AuthZEN authorization decision interface
  • W3C verifiable credentials and an open-source verifier

From organizational request to verifiable decision.

Both organizations retain their own identity, evidence boundaries, policy authority, and signing controls. Bifrost governs the exchange between them; neither side hands its infrastructure to the other.

  1. Authenticate the principal and establish the relevant organizational identity.

  2. Verify the agent’s delegated authority, purpose, scope, and limitations.

  3. Evaluate the exact request against applicable access and counterparty policies.

  4. Release authorized evidence-backed information or issue the applicable signed action decision.

  5. Generate signed artifacts recording the action, decision, supporting context, and subsequent acknowledgment or reported execution.

  6. Allow the receiving organization to independently examine the cryptographic and authorization claims.

When authorization or the required evidence is unavailable, Bifrost refuses and records why. A refusal is not a failed operation. It is part of the trust model.
