The security and authorisation layer for autonomous AI in regulated and mission-critical environments, controlling every agent, action, delegation and tool call before execution.

AI agents can access production systems, call MCP servers, move data, trigger transactions and delegate authority to other agents. Traditional IAM authenticates access, but it was not designed to decide whether an autonomous agent should perform a specific action right now.
Agents often inherit credentials whose permissions exceed the task they are performing.
One agent can delegate work to another. Without enforced delegation boundaries, authority can spread across an agent chain.
MCP servers and external tools dramatically expand what an agent can reach. Every tool invocation needs an enforceable permission boundary.
Traditional logs show what happened. They rarely prove which authority permitted the action, under which rule, and through which delegation chain.
The Authorisation Layer is the platform. Agent identity, delegation, tool security and cryptographic provenance are enforced through it, while Xybern Redact keeps sensitive data out of the prompt before the model ever sees it.
Register first-party and external agents, assign scoped authority, constrain delegation and revoke access independently.
Intercept agent actions in real time and allow, deny or escalate them according to deterministic enterprise charter.
Every authorisation, delegation, escalation and action is recorded with tamper-evident proof.
Six stages. Every agent action. No bypass. It is framework and model agnostic, so it works with CrewAI, AutoGen, LangGraph, and any custom multi-agent system you already run.
Every action enters Xybern before it reaches the target system.
Resolve the cryptographic identity of the agent, service or external workload attempting the action.
Determine its active mandate, inherited constraints, delegation chain, session context and allowed capabilities.
Evaluate the requested action against the active Charter and contextual conditions.
Allow, deny or pause for human approval before anything executes.
Sign the decision and preserve its complete authorisation lineage in the Provenance Vault.
Identity, delegation, tool security, containment and proof, the rest of the controls that sit on the Authorisation Layer. Explore any of them.
Decide which agent may call which tool, with what arguments.
ExploreAuthority narrows at every delegation boundary.
ExploreContain or kill any agent, instantly.
ExploreTrust external agents without their authority.
ExplorePause for a person at the irreversible boundary.
ExploreEmergency access, time-boxed and recorded.
ExploreAuthority that expires on time.
ExploreEvery agent, identified and accountable.
ExploreRoles and least privilege per agent.
ExploreApprove the plan once, enforce every step.
ExploreAn open, reproducible benchmark of 137 attack and legitimate scenarios drawn from OWASP, MITRE ATLAS, and CWE. The authorisation layer caught every unsafe action and blocked no legitimate one. A keyword guardrail cannot.
For every autonomous action, Xybern preserves who acted, which authority they held, how it was delegated, which charters were evaluated, what was decided and what executed, as signed, tamper-evident evidence.

Choose the deployment model that matches your regulatory, sovereignty and security requirements, from managed Xybern infrastructure to isolated and customer-controlled environments.
Deploy Xybern as a managed service with isolated organisation environments, encrypted data and centrally managed security controls.
Learn moreDedicated infrastructure, isolated storage and configurable networking, retention and security controls for regulated workloads.
Learn moreKeep sensitive workloads, charter enforcement and security evidence inside approved customer or sovereign infrastructure.
Learn moreWhen an AI agent makes an unauthorised decision in your industry, the cost is not a rollback. It is a regulatory event.
Control autonomous access to sensitive systems, enforce chain-of-authority boundaries and retain verifiable proof of every machine decision.
Immutable, in-perimeter recordHow we help →Authorise payments, customer-data access, trading operations, privileged workflows and agent-to-agent delegation before execution.
Every action carries a signed receiptHow we help →Constrain how agents interact with patient data, clinical systems and high-impact workflows while preserving human approval for critical actions.
Delegations expire automaticallyHow we help →Control autonomous actions across industrial, energy, telecommunications and other mission-critical environments where unintended execution can have physical consequences.
Fail-closed, human at the boundaryHow we help →Start with one workflow. Deploy in days, not months. See the pipeline and Provenance Vault in action.
