Authorisation for AI agents. Every action. Authorised or denied.

Your AI agents trigger payments, access databases, and execute workflows, all with system-level permissions. No identity. No scope. No one deciding what they're allowed to do.

Xybern is the authorisation layer that decides.

Okta controls what your employees can access. Xybern controls what your AI agents can do.

Any model. Any agent. Any framework. Authorised before execution.

Not monitoring. Not guardrails. Authorisation.

Your AI agents operate today without identity, without permissions, without any authorisation layer deciding what they're allowed to do. They initiate transfers, query databases, and export records, all running with the same permissions as the system that hosts them.

Without Xybern
  • Agent triggers wire transfer runs with system permissions no one checked if it was authorised
  • Agent queries production database exports 50,000 records no permission boundary defined
  • Regulator asks who authorised an AI action no identity, no policy, no record exposure
  • Agent A delegates to Agent B Agent B inherits full system access no scope control
With Xybern
  • Agent triggers action identity verified, permissions checked authorised or denied
  • Agent queries database scoped to its permission boundary read allowed, bulk export denied
  • Every authorisation decision recorded with agent identity, policy, and cryptographic proof audit-ready
  • Agent A delegates to Agent B only delegated permissions transfer scoped authority chain

Employees need credentials to access systems.
Your AI agents should too.

The authorisation pipeline

5 stages. Every agent action. No bypass.

Every AI agent action passes through all 5 authorisation stages. Identity is verified. Permissions are checked against policy. The decision is recorded cryptographically. Framework-agnostic. Model-agnostic.

Not authorised? Doesn't run.

The control plane

Every authorisation decision. Every agent. On record.

Not an observability dashboard. The authorisation control plane. Every entry is a decision, which agent requested what action, which policy governed it, whether it was authorised or denied, and the cryptographic proof behind every verdict.

  • Real-time authorisation feed
  • Agent identity & policy outcomes
  • Cryptographic audit exports

The Provenance Vault

Every authorisation decision, which agent, which action, which policy, authorised or denied, is anchored in a SHA-256 cryptographic hash chain with HMAC-SHA256 signatures. The Vault is the immutable audit trail of every decision Xybern made, with Merkle proof verification and exportable evidence.

When a regulator asks who authorised an AI action, and under the EU AI Act, the SEC's evolving guidance, and enterprise audit requirements they will, the Provenance Vault is your answer. Every authorisation decision. Cryptographically provable. Tamper-evident.

Developer experience

Define agent permissions in code. Deploy through Xybern.

Authorisation policies are code, versioned in git, tested in CI, deployed through the control plane. Define what each agent can do, set limits, and Xybern enforces them deterministically at runtime.

  • Version-controlled policies, audit who changed what and when
  • Test policies before deployment, shadow mode evaluates without enforcing
  • Pre-built templates for EU AI Act, FCA, SEC, HIPAA, SOC 2

Two ways to deploy. One authorisation standard.

Same authorisation pipeline. Same agent identity. Different integration pattern.

Embedded

For Platform Providers

Xybern integrates directly into your AI product stack. It sits between your agents and the actions they attempt to perform.

  • Every agent gets a cryptographic identity
  • Every action checked against permission boundaries
  • Authorisation decisions are deterministic
  • Policy engine evaluates scope in real time
  • Every decision anchored in immutable audit trail

Xybern becomes the authorisation and identity layer within your AI platform.

Centralised

For Enterprises

Xybern deploys as the authorisation layer above all your AI systems. It does not replace models. It controls what they're allowed to do.

Deploys above your existing AI stack. Nothing ripped out. No model replacements. One endpoint. Every agent authorised.

  • Internal LLMs
  • Employee AI copilots
  • Multi-agent workflows
  • Customer-facing AI

No AI agent operates without authorisation.

Built for regulated environments.

Same authorisation pipeline. Policy rules pre-configured for your regulatory context.

Financial Services

Trading decisions, wire transfers, client communications. Every agent action authorised against regulatory policy before execution.

Legal Services

Document execution, contract actions, client data. Every agent authorised against privilege boundaries and supervision rules.

Cybersecurity

Threat assessments, access decisions, incident response. Every autonomous security action authorised against defined boundaries.

Defence

Intelligence processing, classification, operational decisions. Every agent action authorised against clearance scope before execution.

Healthcare

Patient records, clinical workflows, diagnostic data. Every agent action authorised against patient data boundaries before execution.

Insurance

Claims processing, underwriting decisions, policy actions. Every agent decision authorised against conduct rules before execution.
