Website Overview
Several search or sharing settings need attention. Together they may make snippets, preview images or preferred URLs less consistent across platforms.
Domain and Registration
Unknown
DNS and Email
Nameservers are provided by usna.edu, indicating managed DNS hosting. MX records point to the Google Workspace email service. No CNAME was found; the observed records resolve directly to addresses. SPF and DMARC are configured. DKIM status is unknown. TXT records include verification markers for Google, Apple, Microsoft. Such markers may also remain after a service stops being used.
TLS and Certificates
The certificate includes the organization field United States Naval Academy. The certificate issuer is DigiCert Inc, a commercial certificate authority. The certificate uses an RSA 2048-bit public key, offering broad client compatibility. The server supplied a complete certificate chain. The certificate is valid for about 198 days in total, with 94 days remaining.
HTTP and Browser Security
The response lacks these common security headers: CSP, X-Content-Type-Options, Referrer-Policy, Permissions-Policy. CORS permits any origin to read this response. This is common for public resources; sensitive responses need narrower handling. No X-Powered-By header was found, reducing one common source of backend fingerprinting information. No obvious internal addresses or debug information were found in the headers. Cookie security attributes are unknown.
Technology Stack Analysis
The public page identifies Google Analytics without precise versions, leaving fewer clues for version-specific scanning.
Search and Social Sharing
The canonical URL points to another host: https://www.usna.edu/homepage.php. Search engines may consolidate indexing signals there. No Open Graph metadata was detected, so social previews may depend on platform inference. Twitter Card metadata is configured. The title has 48 characters, within a common display range. A meta description is present, with 155 characters.
