Agents

Give every agent
an identity

Issue it, scope it, and keep a record of everything it did.

Issue

An identity per agent

Register each workload. It holds named scopes, a tenant, and an expiry. Revoke stops the next call.

Decide

Policy you can read

Roles, attributes, or relationships. One decision point answers for people and agents alike.

allow if {

agent.scope == "tools:invoke"

resource.tenant == agent.tenant

Investigate

A trail for every call

Each tool call is logged with who acted and from where. Abuse detection flags what looks wrong.

Identity, built in

The boring security,
already on

MFA, sessions, and abuse checks you shouldn't have to remember to turn on.

Multi-tenancy

Workspaces that stay apart

Give each customer, product, or team its own tenant. Invite people by email, assign a role, and keep projects and users on the tenant you selected.

Explore multi-tenancy

Roles and access

Owner, admin, and viewer. Each person gets a seat on the tenant.

acme.com

Verified domains

Add the company domain and confirm it with DNS. Identity hostnames stay on that tenant.

Invite this person

Invitations

Email an invite with a role. Choose which tenants they can open when they accept.

Switch tenant

Organization, then tenant. The console and the CLI follow the same path.
