DigiCert backs NVIDIA OpenShell with verifiable agent identity

DigiCert announced support for the NVIDIA Open Agent Safety Platform: its AI Trust Manager issues cryptographically signed AI Passports, defines allowed actions via policy "visas," and can revoke authority with a kill switch. NVIDIA OpenShell enforces policies outside the agent's process and adds hardware-isolated monitoring via NVIDIA Sentry on BlueField-4.

• AI Passport cryptographically verifies an agent's identity and owner
• Policy "visas" define system, data and action access plus duration
• Kill switch revokes authority and quarantines misbehaving agents
• OpenShell enforces policy outside the agent process and logs decisions
