# GraphnAI > GraphnAI is a self-hosted identity security platform. It maps every identity and permission in your directories, Active Directory and Microsoft Entra ID, into one graph, labels how much evidence stands behind each relationship (Theoretical, Constrained or Validated), finds the attack paths to Tier 0 and the junctions they pass through, detects identity attacks in domain controller security events, and fixes problems through Select Fire, which simulates every change first and only runs changes it can reverse. Graphne is its AI assistant: it answers in plain language through a read-only database account and shows its work. A free 30-day Public Preview runs on your own server. Each page below is also available as Markdown: add .md to its address. ## Product - [How it works](https://www.graphnai.com/product.md): Tables that open into graphs. - [See what's real](https://www.graphnai.com/product/exposure.md): Fidelity tiers, attack paths, posture. - [Play the graph](https://www.graphnai.com/play.md): Explore a sample company in your browser. - [Fix it safely](https://www.graphnai.com/product/remediation.md): Simulate, Select Fire, roll back. - [Catch attacks](https://www.graphnai.com/product/detection.md): Detections, triage, investigations. - [Graphne](https://www.graphnai.com/product/graphne.md): The agent that shows its work. - [Integrations](https://www.graphnai.com/integrations.md): Directories, telemetry, sign-in, API. ## Get started - [Start your free Preview](https://www.graphnai.com/preview.md): 30 days on your own server, from your first sync. - [Trust](https://www.graphnai.com/trust.md): architecture, data handling, keys, AI controls and support access. - [Documentation](https://www.graphnai.com/docs/): user guides for every feature. - [Changelog](https://www.graphnai.com/changelog.md): what shipped, week by week. ## Company - [About](https://www.graphnai.com/about.md) - [Press](https://www.graphnai.com/press.md) - [Blog](https://www.graphnai.com/blog.md) - [Careers](https://www.graphnai.com/careers.md) - [Contact](https://www.graphnai.com/contact.md)
