# Introduction

> AI Agent Identity Governance for modern teams

# What is NullBridge?

NullBridge gives your AI agents a cryptographic identity, secure credential vault, continuous audit trail, and behavioral anomaly detection — in three lines of code.

As AI agents proliferate across your organization, NullBridge answers the question: **who authorized this agent, what can it access, and what has it done?**

## The Problem

AI agents are being deployed faster than governance frameworks can keep up. Most organizations have no answer to:

* Which agents are running in production right now?
* Who approved them and why?
* What credentials do they hold?
* Has any agent behaved anomalously?
* How do you revoke access instantly if something goes wrong?

## The Solution

NullBridge provides a complete identity governance layer for AI agents:

  <Card title="Agent Registry" icon="shield">
    Every agent gets a cryptographic identity at registration. Full ownership, tier, and scope tracking.
  </Card>

  <Card title="Credential Vault" icon="lock">
    Credentials stored with AES-256-GCM encryption. Automatic rotation and revocation with full audit trail.
  </Card>

  <Card title="SIEM Events" icon="bell">
    Every agent action logged in real time. Policy violations, anomalies, and kill switch events surfaced immediately.
  </Card>

  <Card title="Kill Switch" icon="bolt">
    Revoke any agent instantly — token blacklisted, vault sealed, SIEM event logged. One click.
  </Card>
</CardGroup>

## How It Works

1. **Install the SDK** in your AI agent's codebase
2. **Register the agent** — it appears in your NullBridge dashboard immediately
3. **Monitor** — every action is logged, anomalies are detected automatically
4. **Control** — kill, restore, or rotate credentials from the dashboard at any time

## Architecture

NullBridge runs inside your infrastructure. There is no shared SaaS database — your data stays yours.

* **Dashboard** — `app.nullbridge.ai`
* **API** — `api.nullbridge.ai`
* **SDK** — `@nullbridge/sdk` on npm
* **License** — validated on startup, rechecked every 24 hours
