Secure Your Team’s AI Usage
Without Blocking AI
Lightweight browser-level controls that prevent sensitive data leakage into generative AI tools like ChatGPT, Claude, and Gemini.
The Blind Spot
- Invisible Usage: Employees use AI daily on personal accounts outside corporate view.
- Data Leakage: PII, API keys, and internal code are pasted into prompts with zero active filtering.
- Heavy Alternatives: Enterprise browsers are expensive, require network rerouting, and frustrate users.
The PromptFence Solution
- Browser-Based: A lightweight extension that sits between the user and the AI model.
- Real-Time Governance: Analyzes input fields *before* submission. Blocks or warns instantly.
- Zero-Trust Privacy: We log the security event (who/when/rule), but we never store prompt content.
