Shadow AI - PII Firewall

Protect sensitive data when using AI tools. Auto-sanitizes PII before sending to ChatGPT, Claude, and other AI services.

Use public AI tools safely—without the Enterprise price tag. Your team is already using AI to write emails, analyze contracts, and summarize reports. But are they pasting sensitive client data, financial records, or patient details into public models? "Shadow AI"—employees using personal AI accounts for work—is the fastest-growing security risk for small businesses in 2025. ShadowGuard acts as a secure sanitization layer between your employees and AI platforms like ChatGPT and Claude. We ensure you get the productivity of AI without the risk of a data breach. HOW IT WORKS Type Normally: Your employee types a prompt into ChatGPT (e.g., "Draft a letter to John Smith about his $50,000 debt"). Auto-Redaction: Before the request hits the internet, ShadowGuard detects sensitive data and replaces it with secure placeholders (e.g., "Draft a letter to [PERSON_1] about his [MONEY_AMOUNT] debt"). Local Restoration: The AI generates the response using the placeholders. ShadowGuard then instantly re-inserts the original data locally on your screen. The Result: You get the perfect AI response, but the AI provider never sees your private data. KEY FEATURES Smart PII Detection: Automatically detects and masks Names, Emails, Phone Numbers, Social Security Numbers, Credit Cards, and Crypto Wallet addresses. Browser-Based Security: All redaction happens locally on your device. Your unencrypted data never touches our servers. Zero-Friction Workflow: No clunky copy-pasting into a separate app. We overlay directly on top of ChatGPT and Claude. Privacy-First Analytics: Admins can see how much AI is being used across the team to prove ROI, without ever seeing what is being written. COMPLIANCE READY Help your organization meet GDPR, CCPA, and HIPAA requirements regarding data processing. Stop the "Copy-Paste" breach before it happens. Install ShadowGuard today and turn your biggest security risk into your biggest productivity asset.
