- Security Headers - HSTS, X-Frame-Options, X-Content-Type-Options, etc.
- Header evidence - The tracked header values used to compare security posture
- Response Metadata - Status codes, response times, user agents
Key Features
- Automatic Collection - Headers are captured when the site's scheduled security-header check runs
- Historical Tracking - View header changes over time
- Security Analysis - Identify missing or misconfigured security headers
- Filtering & Search - Find specific headers or time periods easily
