Guardian Agent Defense The control plane for autonomous AI

AI agents can act.Your business needs to control them.

AI agents are moving from answering questions to taking action. They access systems, communicate with customers, purchase products, modify records, execute transactions, and make decisions on behalf of people.

Guardian gives enterprises the control layer for this new world.

The Problem

Your employees aren't the only
ones using your systems anymore.

Soon, millions of autonomous AI agents will act on behalf of employees, customers, vendors, and other businesses. They won't just read information — they'll do things.

Purchase products

Place orders and commit spend without a human in the loop.

Move money

Initiate transfers, payouts, refunds, and settlements.

Access sensitive data

Read regulated, personal, and confidential records at scale.

Modify records

Write, overwrite, and delete system-of-record state.

Send communications

Speak to your customers, partners, and regulators as you.

Execute workflows

Chain dozens of downstream actions from one instruction.

Negotiate with other agents

Transact machine-to-machine, at machine speed.

Interact with your APIs

Reach straight into your infrastructure with valid credentials.

The assumption that's breaking
A human is behind every action.

Most enterprise security was designed around that single idea — and that assumption is disappearing.

The Urgency

The agentic internet is arriving
faster than enterprise defenses.

Your customers are deploying AI agents.
Your employees are deploying AI agents.
Your competitors are deploying AI agents.
And your systems will soon transact directly with other companies' agents.
The question was
"Should we allow AI?"
The question is
"What is this AI allowed to do?"

Without an agent control layer, organizations risk losing visibility and control over autonomous activity — and the cost of getting this wrong increases as AI becomes more autonomous.

RISK 01

Legitimate credentials, unintended action

An agent holding valid access can perform actions its human owner never intended — and nothing in the access log looks wrong.

RISK 02

The compromised agent

Once subverted, an agent becomes an attack vector that already holds trusted access to your systems.

RISK 03

The over-permissioned agent

Granted more authority than its job requires, an agent becomes a standing insider threat that never sleeps.

RISK 04

The untrusted external agent

An outside agent can probe, transact, and iterate against your systems at machine speed, around the clock.

The Solution

Guardian Agent Defense

The security and control layer for autonomous AI. Guardian sits between AI agents and the systems they interact with — establishing who the agent is, what it is allowed to do, and whether each action should be permitted.

01

IDENTIFY

Know every agent.

  • human owner
  • organization
  • purpose
  • permissions
  • risk level
  • expiration
  • transaction limits

No anonymous autonomy.

02

CONTROL

Define what agents can do.

  • systems accessed
  • data read
  • actions performed
  • transactions executed
  • spending limits
  • time & location
  • human approval gates

Permission should be explicit — not assumed.

03

DETECT

Analyze every consequential action.

  • unusual activity
  • privilege escalation
  • abnormal volume
  • unexpected data access
  • policy violations
  • suspicious workflows
  • compromised agents

When behavior changes, Guardian knows.

04

DEFEND

Stop dangerous actions before they happen.

  • allow
  • challenge
  • escalate
  • block
  • respond

Enforcement at the moment of action.

Five verdicts on every consequential action

Allow

The action is within policy. Proceed normally, with a full record.

Challenge

Require additional verification before the action continues.

Escalate

Route to a named human for explicit approval.

Block

Stop the action. It never reaches your systems.

Respond

Contain the agent and trigger an incident response workflow.

From Visibility to Control

Traditional security asks who logged in.
Guardian asks what is about to happen.

Traditional security

It asks
"Who logged in?"
It records

Guardian Agent Defense

It asks
"Which agent is acting, on whose behalf, with what authority, and why?"

Every consequential AI action becomes observable, governable, and auditable.

The Agent Firewall

Put a policy boundary between
autonomous AI and your business.

Built for the Agentic Enterprise

One control layer,
every kind of agent.

Internal

An employee's AI assistant, operating inside your walls with your credentials.

External

A customer's purchasing agent, transacting with your business on their behalf.

Third-party

A vendor or partner's autonomous system, reaching into your supply chain.

Autonomous

An AI system operating without continuous human supervision at all.

Common Questions

AI agent security, explained.

What is AI agent security?
AI agent security is the practice of governing what autonomous AI agents are allowed to do inside an organization. Unlike traditional application security — which assumes a human is behind every request — agent security establishes a verifiable identity for each agent, binds it to a human or organizational owner, defines the systems, data, actions, and transaction limits it may use, and evaluates every consequential action against that policy in real time.
How is an AI agent firewall different from an API gateway?
An API gateway authenticates a credential and applies rate limits. An agent firewall evaluates intent and authority: which agent is acting, on whose behalf, under what delegated permission, at what risk level — and whether this specific action should be permitted, challenged, escalated to a human, or blocked outright.
Why aren't existing IAM and identity tools enough for AI agents?
Most identity and access management systems were built around the assumption that a human is behind every action. An AI agent holding legitimate credentials can act at machine speed, far outside its owner's intent, without ever tripping a conventional access control. Agent security adds the missing layer: delegated authority, per-action policy, behavioral baselines, and human-in-the-loop escalation.
What risks do autonomous AI agents introduce?
An agent with legitimate credentials can perform actions its human owner never intended. A compromised agent becomes an attack vector that already holds trusted access. An over-permissioned agent behaves like a standing insider threat. And an untrusted external agent — belonging to a customer, vendor, or partner — can interact with your systems at machine speed without human review.
Does Guardian Agent Defense work with external and third-party agents?
Yes. Guardian applies one common control layer to internal agents such as an employee's AI assistant, external agents such as a customer's purchasing agent, third-party agents operated by a vendor or partner, and fully autonomous systems running without continuous human supervision.

Don't just deploy AI.
Control it.

AI agents will become one of the most powerful interfaces to your business. Guardian makes sure that power comes with:
