Syntix Guardian

Browser security and permission control with redirect analysis, UX scam signals, temporary grants, and extension auditing.

Syntix Guardian helps you detect suspicious browsing behavior before it turns into a mistake. It monitors redirect chains, scans pages for scam-like UX patterns, and gives you clear, explainable alerts in a side panel with actionable steps. The extension is built with a privacy-first model: data is stored locally in your browser, and host access is always user-controlled. Key capabilities: - Redirect risk analysis with explainable reasons - UX scam signal scan (fake urgency, deceptive prompts, suspicious overlays, redirect hints) - Real-time notifications and badge alerts for high-risk events - Incident timeline in Side Panel (“Why this alert” evidence) - Temporary site permission grants with auto-expiry and rollback - Optional extension audit mode (management permission, on user request only) - Optional domain blocklist via Declarative Net Request rules - Scan exclusions and configurable retention/privacy settings Privacy and control: - No hidden permission prompts - Optional host access can be granted per site or globally - URL query storage is disabled by default - Optional hostname obfuscation mode for local logs How To Use (User Instruction) Quick start: 1.
