About Prompt Fence

PromptFence — Enterprise AI Data Loss Prevention Stop sensitive data from leaving your organization through AI chatbots. PromptFence gives IT and security teams visibility and control over what employees share with ChatGPT, Claude, Gemini, GitHub Copilot, and other AI tools. WHY PROMPTFENCE? AI tools are transforming productivity — but they're also a major data leak risk. Employees paste code, customer data, financials, and proprietary information into AI chats every day, often without realizing the consequences. PromptFence solves this by: • Detecting sensitive content before it's submitted • Warning users in real-time about risky prompts • Blocking paste and file uploads when policies require it • Logging all AI interactions for compliance and audit FEATURES Real-Time Protection Scans prompts for PII, credentials, API keys, source code, and custom patterns you define. Warns or blocks before data leaves. Centralized Admin Dashboard Configure policies, view events, manage users, and export audit logs — all from one place. Works Where Your Team Works Supports ChatGPT, Claude, Google Gemini, Microsoft Copilot, and more. New platforms added regularly. Flexible Enforcement Choose your protection level: monitor-only, show warnings, or hard-block sensitive content. Privacy-Conscious Prompt logging is optional and controlled by your admin. Run in monitor-only mode for visibility without storing content. PERFECT FOR • Security teams concerned about AI data exposure • Compliance officers in regulated industries (HIPAA, SOC2, GDPR) • IT admins managing employee AI usage • Organizations handling sensitive IP or customer data GETTING STARTED 1.
