Launch HN: Alter (YC S25) – Access control for multi-user agents
Summary
Alter's PAM solution for AI agents introduces per-agent identities, per-call scope, and an audit trail to prevent credential leakage. It enforces least-privilege with a default-deny policy, supports human approvals, and provides tamper-evident records across 140 provider integrations, aligning with zero-trust and IAM best practices.
