Why Alter

Access control stops at login

IAM assumes a person signing in. Agents make thousands of calls an hour on borrowed credentials, with no identity of their own and no policy on what they call.

Access control has always governed people. Software got a service account and did what it was told, line by line.

Agents ended that. They decide what to call, when, and with what arguments, and they do it with whatever credential was in the environment. The question is no longer whether a person may log in, but whether this piece of software may make this exact call on this person's behalf. Alter answers that question on every request.

The tools you have were built for a different problem

Building it yourself

Months of undifferentiated work

  • Every provider means OAuth quirks, refresh logic, retry behavior, and storage you now own
  • Rotation, revocation, and audit get bolted on later, usually after the first incident
  • None of it is your product

A secrets manager

Stores the secret, then hands it back

  • The credential still ends up in your process, your logs, your prompts
  • No notion of which agent is calling, for whom, or whether it should
  • Nothing pauses a dangerous call for a human

Your IdP or IAM

Governs people logging in, not agents calling out

  • Built for a person at a keyboard with a session, not software making thousands of calls
  • No per-agent identity, no per-call policy, no delegation chain
  • Your IdP stops at login; Alter governs the calls that come after
