Least-privilege access for every machine on your network
ArxLayer Machine Access gives services, automations, and AI agents scoped, token-bound credentials and enforces them at the edge, before any request reaches your origin. Each machine gets exactly the access it needs, and nothing more.
The problem
Machine traffic now outnumbers people, and it's over-trusted
Services, jobs, and agents call each other constantly, often with long-lived secrets that grant far more than they should.
Over-broad credentials
A single shared key or token often unlocks every route, so one leak exposes everything behind it.
Agent-to-agent calls go unchecked
AI agents and automations invoke services and each other with no scope on what they're actually allowed to do.
No clear record of who called what
When a machine identity is abused, teams can't see which token reached which endpoint, or strip its access fast.
What you get
Scoped access, enforced at the edge
Every machine call is authorized against a token bound to a specific identity and scope, before it ever touches your origin.
Identity per machine
Give each service, job, and agent its own non-human identity instead of a shared account or key.
Scoped least privilege
Bind each token to specific endpoints, methods, and tools, so a credential can only do its one job.
Agent and service calls
Authorize agent-to-agent and service-to-service traffic the same way, with one consistent policy.
Authorized before the origin
Unscoped or unauthorized machine calls are rejected at the edge, so your services never see them.
Versioned, reversible policy
Access rules are versioned changes you can review and roll back in seconds, not edits to a secret.
Revoke in one move
Pull a compromised machine identity's access immediately, without redeploying the services behind it.
How it works
From shared secrets to scoped identities
Define machine identities, bind them to scopes, and let the edge enforce every call.
Issue a machine identity
Create a distinct identity for each service, automation, or agent through the API-first control plane.
Bind a scope
Attach a token-bound scope that lists exactly which endpoints and tools the identity may call.
Enforce at the edge
Every machine request is checked against its scope before reaching your origin, with changes rolling out instantly.
FAQ
Questions, answered
- How is this different from a shared API key?
- A shared key usually grants broad access to anyone who holds it. Machine Access binds a token to one identity and a specific scope, so each machine can only reach what it's explicitly allowed to.
- Does this cover AI agents calling tools?
- Yes. Agent-to-agent and agent-to-tool calls are authorized against scoped tokens just like service traffic. It enforces what an agent may call; it does not reason about model intent or detect prompt injection.
- What happens if a machine credential leaks?
- Revoke that identity's access in one move and the edge rejects its calls immediately, without redeploying the services it was talking to.
- Where is access enforced?
- At the edge, before requests reach your origin. The enforcement layer holds no private keys, keeping a clean security boundary.
Give every machine its own scoped access
Replace shared secrets with token-bound identities and enforce least privilege for services and agents at the edge.
