The complete authorisation layer for enterprise AI agents.

Every agent action, authorised in real time. Xybern sits between your agents and the world, enforcing your Charter 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 Charter, 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 mandate 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, risk verdict, assigned mandates, and last action at a glance , across every environment you run.

  • Every agent registered with its identity, risk verdict, and assigned mandates
  • 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, Charter

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

Declare outcomes in plain English, compile them into enforceable mandates, and sign them into your Charter. Test against real historical traffic before going live. Package into deployable Charter versions you can roll back in seconds.

  • Rules defining what each agent can do, what gets blocked, and what gets escalated
  • Backtest mandates against real historical traffic before going live , zero production impact
  • Versioned, deployable Charter releases , deploy, roll back, and track every change
  • Role-based mandates define exactly what each agent is and isn't permitted to do
  • Connect third-party agents from partner organisations into your Xybern workspace, apply your Charter, 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

Backtest against live traffic to see exactly what a new mandate would block before switching it on.

Deploy rules like code

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

Consistent rules across environments

Charter releases ensure your staging and production enforcement stays in sync. No configuration drift.
