From an open-source secrets vault to a AI Agent security platform, Infisical raises funding 40000000 USD Beating Brief:AI Infisical has completed 40000000 USD Series B financing, reaching a valuation of 600000000 USD. This company, incubated by YC, started with open-source secrets management, helping enterprises store API Key, database passwords, and other sensitive information while controlling access permissions. It now has more than 1300 enterprise customers and 300000 developer users, including Airbus, Volkswagen, Hugging Face, and OpenRouter.

As Claude Code, Codex, and other AI Agent begin operating GitHub, databases, and cloud services, secrets security has become a new issue. Agents often need to read external webpages, documents, and code; if manipulated by hidden malicious instructions within them, they may disclose the secrets they hold.

This year, Infisical April open-sourced Agent Vault, allowing Agents to receive only dummy secrets. When accessing external services, requests first pass through a HTTPS proxy, which injects the real secrets before transmission. This means that even if an Agent is manipulated into surrendering the secrets it holds, it cannot directly expose the real passwords.July, the company also launched the commercial version of Agent Proxy, integrating with existing enterprise secrets-management systems.

These capabilities have now been integrated into the commercial Agent Vault. Enterprises can authorize Agents by task, set validity periods, revoke permissions at any time, and log access activity. For example, a code-review Agent receives only the necessary access to GitHub and Slack, which is revoked when the task is complete.

Companies including Anthropic and Vercel have also adopted similar credential-proxy technology. Infisical has made it into independent security infrastructure that can be shared by different Agents, including Claude Code, Codex, and OpenClaw.
