What it protects against: - PII — SSNs, credit cards, passport numbers, email addresses - API keys and credentials across all major AI providers - Private keys, JWTs, and authentication tokens - Database connection strings and internal infrastructure data - .env file values and secrets Two layers of protection: - Payload scanner — intercepts and scans every outbound request - Domain guard — warns when you navigate to sensitive pages while an AI session is active Everything runs locally. No accounts, no cloud, no telemetry. Your data never leaves your machine. Open source: github.com/Katherine-Holland/ClaudeCoworkGuard
