Everything touches only what it is authorised to touch.

The same enforcement principle Xybern applies to agents, every action verified, every access bounded, every decision recorded, applies to the humans and systems accessing Xybern itself. Access control is the same architecture, not a separate policy.

The agent access problem

Most access control was built for humans. Agents are different.

A human logs in, does a task, and logs out. An agent calls your systems thousands of times an hour with no natural pause. RBAC and key scoping are necessary, but not sufficient.

Cryptographic agent identity

Every agent acts under its own signed identity, not a shared key that can never be narrowed or revoked individually.

Authority boundaries

Each agent is bounded to the actions its job requires. Anything outside the boundary is rejected and recorded.

Behavioural baselines

Agent behaviour is tracked against a baseline, so a compromised agent stands out instead of blending in.

RBAC and key scoping

Standard controls still apply to the people and systems around the agent, enforced the same way.

Role-based access

Four human roles. One agent role. Enforced the same way.

Every role, human or agent, has a defined permission scope. Every action outside that scope is rejected and recorded, with no exceptions.

Owner

Full workspace control: billing, security settings, and members. The only role that can change workspace-level security or delete the workspace.

Admin

Manage projects, policies, and members. Cannot change billing or workspace-level security. The standard role for configuring governance.

Editor

Run verifications, create rules, and export reports. Cannot manage members or change security settings.

Viewer

Read-only access to results, vault entries, and reports. Built for compliance officers and auditors who review without acting.

Agent

A scoped, signed identity for each AI agent, bounded to its authorised actions and logged on every call.

Keys & audit

Scope the keys. Log everything.

API keys are scoped to exactly what a system needs, revocable in under a second, and every action they take is written to a tamper-evident log.

API key scoping

Five scopes so each key carries only the access its integration requires, never a blanket credential.

Sub-second revocation

Revoke a key and it stops working in under a second, with in-flight requests using it rejected.

Full access audit log

Every action by a person, system, or agent is recorded, hashed, and chain-linked in the vault.

Key compromise response

A clear, tested path to revoke, rotate, and prove exactly what a compromised key could and could not touch.
