What it is
HTTP headers are the key-value pairs a server sends ahead of the page itself. They cover caching, content type, encoding, compression, security policy, and whatever the server chooses to volunteer about itself.
Why it matters
Headers are the cheapest fingerprint available. They frequently name the server software, the CDN, the framework and the load balancer. The security headers a site has left out are as informative as the ones it sets.
How this assessment works
Skopeon Labs queries public infrastructure signals and authoritative network protocols directly from external sensor nodes. All evaluations are completely non-invasive and agentless, assessing observable configurations without sending malicious payloads or disrupting service.
Operational Scope & Limitations
This check evaluates public perimeter responses observable at the time of inquiry. Endpoints protected behind third-party reverse proxies or CDNs reflect the edge configuration of the proxy layer.
