What this scan covers
- HTTP security headers and CSP policy quality
- TLS/HTTPS configuration and certificate health
- Cookies (HttpOnly/Secure/SameSite) and basic CORS posture
Why regular scans matter
Websites change frequently. Deploys, CDN tweaks, and third-party scripts can introduce drift. Regular scanning catches regressions early so you can fix issues before they become incidents. Use Barrion's continuous monitoring to detect any regressions.
What to do with your results
- Prioritize high‑impact fixes (HSTS, CSP baselines, cookies) first
- Assign owners and track remediation to completion
- Set up recurring scans to maintain posture after fixes
