Solutions
Agents act on the real identity of the person behind them and can never exceed that person’s access. Policies apply across users, groups, tools, and providers. Protoguard inspects every call, and tracing records all of it — control built in, not bolted on.
- 01
No shared credentials to govern
Agents act on the real identity of the person behind them, so there are no broad service tokens to provision, rotate, or contain. An agent inherits exactly what its user is allowed to do, and nothing more.
- 02
One place to set policy
Apply policies across users, groups, tools, and providers from a single control plane. SSO/SAML and your existing groups import in, so access maps to the structure you already maintain.
- 03
Traffic inspected in line
Protoguard sits in front of every agent, catching prompt injection, watching for provider schema changes, and blocking out-of-policy tool calls before they reach your systems.
- 04
Built for where your data has to live
Run providers in isolated enclaves with firewalls, Vault, and KMS, and deploy multi-region or on-prem for data residency. Every interaction is traced against the identity behind it.
Agents inherit a person’s access
With tokenless auth and identity delegation, each agent acts as the person behind it — and can never reach anything that person can’t.
Every call is checked before it lands
Protoguard reviews incoming messages and tool requests, catches prompt injection, and blocks calls outside your policies before they reach your systems.
See exactly what happened
Tracing and audit logs record every interaction against the real identity behind it, so security and operations can review and report without chasing each team for its own logs.

Frequently asked questions
Common questions about AI governance and security.
How do agents get access without shared credentials?
Each agent acts as the person behind it through tokenless auth and identity delegation, so it can never exceed what that person is allowed to do. There are no broad service tokens to issue or rotate. Access control applies policies across users, groups, tools, and providers.Can we review everything agents do?
Yes. Tracing and audit logs record every interaction against the real identity behind it, so security and operations can see exactly what happened.What stops a malicious or out-of-policy call?
Protoguard inspects incoming messages and tool requests before an agent acts, catching prompt injection and blocking calls outside your policies. Sensitive providers can also run in isolated enclaves, and you can deploy multi-region or on-prem for data residency.
