If you want an AI agent to actually do something useful — send an email, update a CRM record, check a calendar — it needs credentials to those services. Handing an autonomous agent your real API keys is risky: if it's manipulated or buggy, it now has broad, standing access to everything those keys unlock. Alter Vault exists to remove that risk by sitting between agents and the 100+ SaaS tools they need to reach, issuing narrow, short-lived, revocable credentials instead of raw keys. Alter Vault (a Y Combinator S25 company, originally launched as alterai.dev) manages OAuth tokens and API keys centrally, verifies agent identity, enforces fine-grained policies on what each agent can do, applies rate limits, and keeps a full audit log of every call made through it. It ships Python and TypeScript SDKs, a developer dashboard, and an end-user portal, and is aimed at teams building agent frameworks or chatbots that need real third-party access without the security exposure of static, long-lived credentials scattered across code.

A security layer for companies that let AI agents take real actions on their behalf (booking things, editing databases, sending messages) — it steps in at the exact moment an agent is about to act and checks whether that action is actually safe to run, in
A tool that sits between you and ChatGPT (or Claude, or Copilot) and swaps out anything sensitive you type — names, medical details, account numbers — with realistic fake stand-ins before it ever leaves your computer, so the AI still understands your ques
A security tool for IT teams that answers a question most companies can't: which of the hundreds of apps and AI agents connected to our Google Workspace, Salesforce or Slack actually have access to what, and are any of them behaving suspiciously right now
A login system for apps that need a crypto wallet behind the scenes — users just sign in with their email or a fingerprint like on any normal app, and Magic quietly creates and manages a real blockchain wallet for them, so nobody has to deal with seed phr
A tool that lets employees and customers log in without a password at all — using something like a fingerprint or device unlock instead — which also means there's no password for a phishing email to steal, and no forgotten-password calls for the help desk
A security tool for the passwords nobody thinks about — not the ones humans type, but the ones baked into scripts, servers and automated jobs that quietly run forever with the same credentials, which is exactly what attackers look for.
A login system that replaces passwords with a cryptographic key tied to your actual device, so there's simply nothing for a hacker to steal or guess — and it now also checks whether the person or AI agent on the other end of a video call or API request is
Scans AI-generated codebases for exposed keys, vulnerable dependencies, and authorization flaws, with plain-English fixes.
Detects deepfakes, face-swaps, and forged documents, with a flagship on-device tool called Halo that flags synthetic faces during live video calls.
Sits between your AI agent and the outside world, catching risky actions — deleting a file, reading a credential, sending money — and holding them for a human to approve before they actually happen.
An antivirus-style watchdog for AI coding agents that runs on your own machine, checking every shell command, file edit and package install before it happens and blocking anything that looks dangerous.
Continuously watches your Supabase project's logs for security problems and explains them in plain language, instead of requiring you to hire a security engineer or learn to read raw audit logs.
