Zero-Trust for AI Agents

Your agents make thousands of decisions a day. Who’s authorizing them?

AI Guardian sits between your AI agents and the systems they touch. Every action is monitored, scored 0–100 for risk, checked against your policies and either allowed, flagged or blocked — before damage lands.

AI Guardian monitoring AI agents across a connected world

Enterprise agents need enterprise controls

AI agents now read your data, call your tools and act on your behalf. AI Guardian gives that autonomy a security perimeter — monitoring, control and accountability in one platform.

See everything

Every tool call, data access, network request and credential use your agents attempt is captured as a structured event — who, what, where, and how much.

Decide instantly

Each action gets a 0–100 risk score and a policy decision: allow, alert or block. Dangerous behaviour stops before it executes, not after it hits the news.

Prove it later

A complete audit trail with evidence, matched policies and analyst review status — the record your security team and your auditors will ask for.

Everything Guardian watches for

Nine event types, continuous scoring and a policy engine you control — the complete picture of what your AI agents actually do.

Real-time risk scoring

A 0–100 score for every action, built from the action type, data classification, destination, authorisation scope, timing and volume — with the reasoning shown factor by factor.

Policy enforcement

Express your rules as conditions on any event field. Policies decide allow, alert or block, and a matched policy sets the minimum severity the action is treated with.

Threat detection

Credential harvesting, data exfiltration, prompt injection, privilege escalation and shadow AI are detected and grouped into investigable threats mapped to MITRE tactics.

Complete audit trail

Immutable event records with evidence payloads, matched policies and risk factors. Analysts confirm threats or mark false positives, straight on the record.

Live event stream

Watch your agents operate in real time. Events stream into the console the moment Guardian scores them — no refresh, no delay.

API-first integration

One endpoint, one API key. Register an agent, stream its events and get scoring decisions back in the response — from any stack your agents run on.

Live in three steps

01

Register your agent

Add the agent in the console — its provider, autonomy level, data access and the capabilities you expect it to use.

02

Issue an API key

Create a scoped key with events:write. Point your agent at the Guardian ingest endpoint and stream every action it attempts.

03

Guardian stands guard

Each event is scored, matched against your policies and recorded. The decision comes back in the response so your agent acts only on what you allow.

Prompt filters aren’t enough

Other tools watch what your agent says. AI Guardian authorizes what it does — every tool call, checked against your policies before it fires.

Security teams sleep better with Guardian

Built for the teams every AI agent answers to.

“We rolled out 30 internal agents last year with no visibility into what they touched. AI Guardian gave us the audit trail our security team demanded — in an afternoon.”

“The risk scoring caught an agent pulling customer records off-hours in its first week. That one alert alone justified the subscription.”

Frequently asked questions

How does AI Guardian see what my agents are doing?

Your agent streams each action to the Guardian ingest API — one authenticated call per event. Guardian scores it, evaluates it against your policies and returns the decision in the same response.

Can it actually stop an action?

Yes. Any policy can be set to block, and actions that cross the risk threshold are blocked automatically. A block decision comes back with the response, so your agent halts before executing anything dangerous.

Does it help with compliance and audits?

Every event is stored with its evidence, risk factors, matched policies and review status. Security analysts confirm threats or mark false positives on the record — a complete, exportable trail.

What counts as an event?

Tool calls, data access and transfers, network requests, credential access, privilege changes, model output, authentication and configuration changes — nine event types covering everything an agent can do.
