AI Agent Trust overview
Gain control of agent sprawl
Inventory every AI agent and extend cryptographic trust across organizational boundaries.
Secure agentic deployments
Discovery, federated identity, policy, and lifecycle management for every agent across your environments.
Find what exists
Discover built and third-party agents across your enterprise and environments in a single unified control plane.
Create a registry
Register agents in a private or public registry, capturing metadata for identity, policy, and control.
Issue passports
Bind agent identity, metadata, policies, capabilities, and authorized human ownership to the AI Agent Passport—a cryptographically verifiable trust artifact.
Enforce policy
Protect agentic sessions by evaluating identity and permissions, with automated kill switching when trust conditions change.
Stay audit ready
Record agent actions, permissions, and outcomes across every session for a tamper-evident audit trail.
Introducing the AI Agent Passport
The AI Agent Passport is modeled after the real thing—proving agent identity and encoding policy across digital environments.
Identity verification
Like a government-issued human passport, the AI Agent Passport carries cryptographic proof of the agent's identity—without shared secrets or passwords.
Interoperability
Physical passports conform to global standards. The AI Agent Passport is also standards-based (NIST NCCoE) and proves trust across vendors, clouds, and agent frameworks.
Privileges
Like stamps and visas in a physical passport, the AI Agent Passport clearly defines agent privileges, showing what the agent can do, when, and where.
Walk through the AI Agent Trust lifecycle
Explore each stage of the AI agent governance lifecycle—from discovery and passport issuance to revocation of privileges and the automated kill switch.
Expose shadow AI and account for every agent
- Discover built and third-party agents across your environments
- Build a private registry for internal use, identifying every agent
- Publish select agents to DigiCert's public agent registry
Give every agent an identity and define policies
Every agent gets a passport, in which you can encode:
- The agent's bound SPIFFE workload identity
- The systems and MCP connections it is authorized to access
- The operations it is permitted to perform
- The environments in which it may operate
- The policies that govern its behavior
- The named accountable human owner responsible for it
Enforce policies to ensure every action is authorized
- Intercept agent traffic at the DigiCert Enforcement Point or via MCP gateway
- Establish a secure, encrypted communication channel using mTLS
- Evaluate passport and permit or deny agent actions based on trust conditions
- Authorize temporary or purpose-specific access based on defined policies
- Automatically kill agent sessions when trust conditions change
Eliminate the risk of standing access
- Automate workflows for passport issuance, renewal, and expiration
- Set criteria for automatic passport revocation based on agent actions, connections, and trust conditions
- Maintain auditable lifecycle state records for every agent
Govern agents with the structural controls they require
- Derive lineage from runtime enforcement and audit events
- Review relationship graphs connecting agents to systems, models, connections, and data classifications
- Maintain a tamper-evident audit trail of agentic sessions
Why leaders choose DigiCert for AI Trust
Internet scale
AI is proliferating quickly, and DigiCert brings the proven expertise in managing trust at internet scale.
Cross-organization trust
The DigiCert AI Agent Passport federates identity and trust across environments and organizations.
Cryptographic identity
With DigiCert, agent identity and policy are cryptographically encoded and verifiable.
"We see DigiCert AI Agent Trust as a promising approach to extending proven principles of digital identity to this new class of autonomous systems. The ability to verify an agent's identity, define what it is authorized to do, and maintain visibility into its actions could give organizations the foundation they need to adopt agentic AI with greater confidence."
