HallGuard is a local-first AI permission firewall that warns before sensitive data, risky uploads, prompt injection, and scam-like language are sent to ChatGPT, Claude, whatsApp, Gmail, etc
AI tools make it easy to accidentally share sensitive data like credentials, source code, and confidential information. HallGuard acts as a security layer between you and AI, detecting risky content before it reaches AI tools and letting you block, review, or safely redact it.
