Website Overview
An established domain and managed infrastructure suggest continuity of operations and may support dependable delivery, although neither guarantees service quality. Several search or sharing settings need attention. Together they may make snippets, preview images or preferred URLs less consistent across platforms.
Domain and Registration
Registered in 1997, this domain has about 28 years of history. That suggests continuity, although ownership and purpose may have changed. Transfer-protection status is present, helping reduce the risk of unauthorized domain transfers. The domain uses .gov, a restricted namespace whose registration normally has eligibility requirements. Registration contact information is publicly available through RDAP.
DNS and Email
Nameservers are provided by usda.gov, indicating managed DNS hosting. MX records point to the Microsoft 365 email service. DNSSEC is enabled, allowing validating resolvers to authenticate signed DNS data. CAA records restrict which certificate authorities are authorized to issue certificates. SPF and DMARC are configured. DKIM status is unknown.
TLS and Certificates
The certificate includes the organization field USDA. 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 124 days remaining.
HTTP and Browser Security
The response lacks these common security headers: CSP, X-Content-Type-Options, Referrer-Policy, Permissions-Policy. 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. The Server header identifies nginx without an exact version. No explicit CDN or WAF marker was found in the response headers.
Technology Stack Analysis
The public page identifies Angular, Google Tag Manager, Google Analytics, nginx without precise versions, leaving fewer clues for version-specific scanning.
Search and Social Sharing
No homepage canonical URL was detected. If duplicate URLs exist, consolidation may be less explicit. No Open Graph metadata was detected, so social previews may depend on platform inference. The title has 21 characters, within a common display range. A meta description is present, with 152 characters. The observed directives allow indexing and link following.
