DigiCert AI Trust Manager gives AI agents a verifiable passport by issuing a cryptographically signed, portable identity credential – the DigiCert AI Passport – that proves who the agent is, who owns it, and what it is authorized to do across systems and organizations.

India, September 30, 2026 — DigiCert, a specialist in intelligent trust, today announced support for the NVIDIA Open Agent Safety Platform to help enterprises establish verifiable identity and authority for autonomous AI agents.

Autonomous agents arrived as a class in 2026, and they arrived fast. Agents operating outside their intended boundaries went from a conference hypothetical to real incident reports. And nearly every conversation with security leaders lands in the same place. Prompt- and model-level safeguards shape what an agent tries to do. They aren’t a boundary. You can never secure a data center by asking the servers nicely, and agents shouldn’t secured that way either. (Source: DigiCert Blog.)

To secure agents you need a real boundary, in both, software and in silicon.

Hence the announcement about the NVIDIA Open Agent Safety Platform. It puts the agent’s boundary where it belongs: in the infrastructure.

How does DigiCert AI Trust Manager complement NVIDIA’s Platform?

At the center of the NVIDIA Open Agent Safety Platform is NVIDIA OpenShell, an open, secure runtime that places infrastructure-level controls around autonomous agents. OpenShell permits nothing by default, enforces policy outside the agent’s process, and records every decision to allow or deny an action. DigiCert complements those controls withDigiCert AI Trust Manager gives AI agents a verifiable passport by issuing a cryptographically signed, portable identity credential—the DigiCert AI Passport—that proves who the agent is, who owns it, and what it is authorized to do across systems and organizations.hich helps organizations discover and manage the AI agents they own or operate, establish each agent’s verifiable identity and ownership, define what it is authorized to do, and revoke that authority with a kill switch when trust changes.

Together, the technologies address two critical requirements for autonomous AI: identifying which agent is acting and controlling what an agent can do.

“AI agents are starting to do real work across business systems, and that means companies need to know exactly which agent is acting, what it’s allowed to do, and when to stop it,” said Amit Sinha, CEO of DigiCert. “NVIDIA helps create the boundary around the agent. DigiCert helps establish who that agent is and what authority it has. Together, that gives enterprises a much clearer way to put autonomous AI to work with control and accountability.”

Why do AI agents need a verifiable passport?

NVIDIA OpenShell lets an agent retain its reasoning and skills while every file, network, process, credential, and inference call crosses a boundary controlled by the platform. Because enforcement occurs outside the agent’s process, even a compromised agent cannot override the restrictions. NVIDIA Sentry on BlueField-4, powered by NVIDIA DOCA, adds hardware-isolated, out-of-band monitoring of agent activity and security-policy enforcement that does not dependon the host. NVIDIA Vera supplies the compute for agents’ CPU-intensive workloads.

DigiCert AI Trust Manager extends the OpenShell environment with enterprise-class agent management built around identity, authority, policy, and lifecycle control. DigiCert AI Trust Manager gives each agent a DigiCert AI Passport, a portable, cryptographically signed credential that verifies an agent’s identity and connects it to an accountable owner. Policy-based “visas” define which systems, data, and actions the agent may access, as well as how long that authority lasts.

Because the DigiCert AI Passport and its permissions travel with the agent, other systems and organizations can independently verify them without relying on the same identity provider. If an agent attempts a prohibited action, DigiCert’s automated kill switch can block it and, under policies set by the agent’s owner or passport issuer, revoke its authority at the source and quarantine it.

Extending trust across organizational boundaries

DigiCert’s support for NVIDIA Open Agent Safety Platform is designed around four areas:

Identity that policy can act on. Agents running within an OpenShell environment can be associated with an AI Passport so policies can rely on verified identity.
Verification before execution. Agents, models, and MCP servers can be signed and associated with an AI Bill of Materials to help establish what is being deployed before execution.
Auditable evidence. OpenShell records policy allow-and-deny decisions. DigiCert’s approach is designed to bind trusted identity and cryptographic evidence to those interactions, creating a stronger record for governance and audit.
Trust across company boundaries. PKI already enables independent verification of identity across the internet. DigiCert is extending that same trust model to agents so organizations can verify AI identities even when agents interact across companies, clouds and technology environments.

The approach is designed to complement, not replace, the security controls provided by NVIDIA Open Agent Safety Platform. NVIDIA establishes and enforces the agent’s operating boundary. DigiCert provides verifiable identity and authority that can persist as the agent interacts beyond that boundary.

“As agents begin interacting with other agents beyond company lines, identity cannot depend on every participant belonging to the same identity system,” Sinha said. “We need a trust model that can cross those boundaries. PKI solved that problem for the internet at scale, and we believe the same foundation has an important role to play in establishingtrust for autonomous agents.”

DigiCert AI Trust Manager support for NVIDIA Open Agent Safety Platform begins with NVIDIA OpenShell, with additional capabilities planned as DigiCert and NVIDIA continue to advance enterprise AI trust and agent security.
