GPT-Shield – Real-Time AI Security & Data Protection GPT-Shield is an enterprise-grade AI security extension that helps prevent sensitive data, intellectual property, and high-risk business context from being sent to AI tools. It works directly inside ChatGPT and other AI interfaces to reduce data leakage and unsafe prompt submissions in real time. Important: GPT-Shield requires an active GPT-Shield license and the GPT-Shield Desktop Agent (installed separately). If the desktop agent is not running, the extension will display a setup status screen only. As AI becomes embedded in everyday work, organizations face the growing risk of Shadow AI — the uncontrolled use of AI that bypasses security, compliance, and governance safeguards. GPT-Shield is designed to help organizations mitigate this risk at the moment prompts are created. 🔐 What GPT-Shield Does GPT-Shield acts as a real-time “cognitive firewall” for AI usage by inspecting text locally on your device before it is submitted to external AI services. Prevent Data Leaks Detects and redacts sensitive data in real time Helps protect PII, PHI, credentials, internal IDs, and confidential business information Operates before prompts are submitted to AI tools Reduce Risky AI Usage Flags or blocks prompts that may violate security, legal, or compliance policies Helps prevent inappropriate delegation of authority or sensitive decisions to AI Stops unsafe requests before they reach external AI providers Enterprise-Grade Risk Coverage GPT-Shield uses a local AI model trained across seven risk areas: Human Safety (self-harm and distress signals) HR Compliance (bias and ideology risks) Legal Liability (authority delegation) Data Security (PII and IP exposure) Infosec (hacking or bypass attempts) Trade Secrets (competitive strategy) Sensitive Business Context All inspection happens locally on your device. Your prompts are not sent to third parties by GPT-Shield. 🧠 Built for Real Organizations Works alongside ChatGPT and other AI tools Enforces policies without disrupting normal workflows Uses context-aware detection instead of simple keyword rules Provides immediate feedback to guide safer AI use Designed for security, compliance, and IT teams ⚡ Why GPT-Shield Most AI security tools detect problems after data has already left the organization. GPT-Shield is designed to help stop incidents before they happen. If your organization uses AI, GPT-Shield helps you do so more safely, confidently, and at scale. 📦 Requirements Active GPT-Shield license GPT-Shield Desktop Agent installed and running Chrome or Chromium-based browser
