Alter Vault

Alter Vault: Privileged access management tool that enforces security policies, vaults credentials, and audits AI agent actions at runtime.

Alter Vault provides privileged access management for AI agents, enforcing security controls at runtime. It stores credentials in a dedicated secret store and injects them per request so they stay out of code. The platform offers per-agent identity and scopes, default-deny policies, human approval gates for risky calls, and tamper-evident audit trails. It supports 140 providers with first-class LangChain, Model Context Protocol, and AWS integrations. The system is designed for teams building AI agents that need to pass security reviews, call APIs on behalf of users, provision secrets, and stream audit logs to a SIEM.
