The complete authorisation layer for enterprise AI agents.

Every agent action, authorised in real time. Xybern sits between your agents and the world, enforcing policies before anything runs.

01, Authorization

Every action enforced before it runs.

Xybern intercepts every agent action in real time. Each one is evaluated against your policies, logged with a signed decision, and either cleared, blocked, or routed for human review , before the agent touches anything.

Every action your agents attempt, logged with the policy that triggered the result
Sensitive actions held for human approval , the agent waits until you decide

In Practice

Block before execution

Real-time enforcement means nothing runs without a decision. No action slips through unreviewed.

Escalate without halting everything

Route sensitive actions to a reviewer instead of a hard block. The agent waits. Work continues.

Satisfy auditors on demand

Every decision is signed and exportable. No manual log assembly when regulators come asking.

02, Agent Control

Full visibility and control over every agent in your system.

Register, monitor, and govern every AI agent from a single place. Know their identity, trust score, assigned policies, and last action at a glance , across every environment you run.

Every agent registered with its identity, trust score, and assigned policies
Scoped, time-limited agent-to-agent delegations , every use logged
Time-based windows that restrict when agents can act , outside the window, blocked automatically
Emergency bypass that is logged, time-limited, and requires a stated reason

In Practice

No anonymous agents

Every agent is registered with a verified identity before it touches production. No action without attribution.

Privilege escalation is structurally impossible

Agent A cannot pass more permissions to Agent B than it holds itself. Enforced at the infrastructure level.

Emergency access, still audited

Breakglass gives your team an exit that satisfies your audit trail. No undocumented overrides.

03, Policy Engine

Rules your agents live by, written once and enforced everywhere.

Write, simulate, and deploy enforcement rules as versioned policy objects. Test against real historical traffic before going live. Package into deployable bundles you can roll back in seconds.

Rules defining what each agent can do, what gets blocked, and what gets escalated
Test policies against real historical traffic before going live , zero production impact
Versioned, deployable policy packs , deploy, roll back, and track every change
Role-based policies define exactly what each agent is and isn't permitted to do
Connect third-party agents from partner organisations into your Xybern workspace, apply policies, set boundaries, and authorise exactly what they can do
HMAC-signed webhook notifications for every enforcement decision, with automatic retry delivery

In Practice

Test before you enforce

Run policy simulation against live traffic to see exactly what a new rule would block before switching it on.

Deploy rules like code

Version control, review, and roll back your enforcement policies the same way your team manages a codebase.

Consistent rules across environments

Policy packs ensure your staging and production enforcement stays in sync. No configuration drift.

Provenance Vault

A complete record of every agent action, forever.

Xybern's Provenance Vault captures a cryptographically signed log of every decision, who authorised it, and why. Designed for regulated industries where auditability is not optional.

Immutable, signed audit records per action
Full decision context, including denied requests
Exportable for SIEM, compliance, and legal review
Retention controls aligned to your regulatory requirements

Deploy in days. Authorise everything.

Xybern integrates with your existing AI infrastructure without replacing any models or systems. Your engineering team gets full API and SDK access. Your compliance team gets the audit trail.
