Getting Started
PII Firewall automatically detects and masks personal information before it reaches AI services — protecting your privacy without interrupting your workflow.
What PII Firewall Does
- Detects 24 types of PII — names, email addresses, phone numbers, credit card numbers, passport numbers, and more
- Masks automatically — sensitive data is replaced with tokens before leaving your device
- Blocks AI attacks — detects 10 categories of prompt injection and jailbreak attempts
- Restores responses — AI responses are returned with your original data restored locally
