Privileged access management for AI agents.
Control what agents can do on behalf of each user. Enforce policy, keep credentials private, and audit every action.
Give agents their own keys, not yours .
Keys scattered everywhere
Pasted into prompts, configs, and .env files across every repo.
One key does everything
Every agent borrows the same over-scoped credential.
No answers afterward
Nobody can say which agent did what, or on whose behalf.
One vault
Stored once and injected per request, so proxied calls keep it out of your code.
Least privilege per agent
Each agent gets its own identity and scopes, with a human gate where you want one.
Every action on the record
A tamper-evident trail with a name attached to every call.
Pass your customers' security review
Per-agent identity and scoped grants instead of one shared key
Policy and human approval a customer's security team can inspect
An audit trail you can hand to a reviewer, streamed to their SIEM
PAM controls for a new kind of privileged user
See every call an agent makes through Alter: which agent, whose access, which policy, who approved
Default-deny policy down to the parameter, and approval for risky calls
Revoke an agent, key or grant instantly; IdP webhooks cascade offboarding
Alter authenticates, authorizes, and logs every request
One SDK call handles storage, refresh, policy, and audit for 140 providers. First-class LangChain, MCP, and AWS integrations.
One platform between your agents and every API
Credential Vault
Store credentials once. Agents use them without ever seeing them.
Policy Engine
Each request checked against your rules. Deny by default.
Agent Identity
Per-agent keys and scopes, traceable to a real person.
Human in the loop
Sensitive calls wait for a named person. Everything else flows.
Compliance & Audit
A record you can hand to an auditor, streamed to your SIEM.

What teams build on Alter
Every card is a working guide with code.
Call APIs on behalf of users (opens the guide in a new tab)
Run OAuth, Connect, and identity-aware token retrieval end to end.
Give an AI agent scoped access (opens the guide in a new tab)
The agent gets its own identity, its user grants, and its own audit trail.
Provision secrets for backend services (opens the guide in a new tab)
Store API keys and service tokens in Alter instead of environment variables.
Expose credentials to Claude Code (opens the guide in a new tab)
Build your own MCP server that serves Alter-managed credentials as tools.
Partition agent memory by identity (opens the guide in a new tab)
Key memory, sessions, and channels by verified identity, never by what the LLM claims.
Build a multi-user server (opens the guide in a new tab)
Serve many users from one service without the credential entering your process.
How the platform itself is secured
Credentials live in a dedicated secret store, encrypted at rest, with keys managed outside the application database
Fail-closed authorization: if a policy cannot be evaluated, the request is denied
Zero-trust ownership: a key confers no capability without an explicit record naming it
Postgres holds metadata and vault references; provider tokens and credentials live only in the vault
Per-key isolation, plaintext credentials never in logs, and proxy-only keys that cannot retrieve a credential at all
Controls monitored continuously
Our trust center publishes the live state of our security program: monitored controls, an independent penetration test within the last 12 months, and security policy documents on request.
