Shadow AI Sentinel

See every AI your company uses — free. Policy enforcement and one-click EU AI Act & ISO 42001 compliance evidence.

Your company runs dozens of AI tools. Your security team can name three. Shadow AI Sentinel is a free browser extension that shows your organization exactly which AI services are being used, enforces your AI policy at the browser, and turns everything into auditor-ready compliance evidence — in one click. WHAT IT DOES • Discovers 140+ AI services (ChatGPT, Copilot, Gemini, Claude, Midjourney, agent platforms…) via a published, versioned allowlist • Shows a live inventory with vendor posture (enterprise vs consumer) and risk tier • Enforces org policy in the browser: block, warn, or allow per domain (policy-as-code, versioned, audit-trailed) • Fleet-wide kill switch for incident response • Generates compliance evidence packs: EU AI Act transparency, ISO/IEC 42001 mapping, insurance readiness (EPC six controls), DPDP × EU joint report HOW ORG MODE WORKS Admins create an organization in the Sentinel console and distribute an install key (via Chrome Enterprise managed policy, or paste it in Settings). Employees just browse normally — nothing else changes. PRIVACY BY ARCHITECTURE • Observes a published list of AI domains only — never reads page content • No PII collected: anonymous device IDs only; org linkage happens server-side • No remote code. Config is cryptographically signed (HMAC-SHA256) and verified locally • Index benchmarking is strictly opt-in and anonymized at source • Erase everything anytime from Settings WHO IT'S FOR Security teams that need shadow-AI visibility today, companies preparing for EU AI Act transparency obligations (live since Aug 2, 2026), and any organization answering AI questions from auditors, customers, or insurers. Free forever for discovery & monitoring. Learn more: https://shadowaisentinel.app
