GuardScope - Email Security

About

GuardScope helps Gmail users inspect suspicious emails before they click links, reply, or open attachments.

The extension analyzes user-selected Gmail messages for phishing, impersonation, suspicious links, sender authentication issues, domain risk, and social-engineering signals. Results appear in a Chrome side panel with an advisory risk score, a plain-English verdict, evidence-backed red and green flags, and suggested next steps.

GuardScope scans only when the user initiates analysis. GuardScope does not store email bodies, subjects, sender details, recipients, headers, or extracted email URLs in its databases after producing the analysis response.

Key features:
- User-triggered Gmail email analysis.
- Advisory phishing and social-engineering risk score.
- Sender authentication checks for SPF, DKIM, DMARC, and alignment signals.
- URL and domain intelligence.
- Domain age and registrar context.
- Business email compromise and impersonation pattern checks.
- No GuardScope email-content storage after analysis.
