Website Overview

An established domain and managed infrastructure suggest continuity of operations and may support dependable delivery, although neither guarantees service quality.

Domain and Registration

Registered in 1997, this domain has about 29 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

The lowest TTL is 10 seconds, supporting rapid record changes at the cost of more frequent lookups. Nameservers are provided by nih.gov, indicating managed DNS hosting. MX records point to the nih.gov email service. DNSSEC is enabled, allowing validating resolvers to authenticate signed DNS data. CAA records restrict which certificate authorities are authorized to issue certificates.

TLS and Certificates

The certificate includes the organization field US Department of Health and Human Services. The certificate issuer is IdenTrust, 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 394 days in total, with 84 days remaining.

HTTP and Browser Security

The response lacks these common security headers: CSP, X-Content-Type-Options, clickjacking protection. No X-Powered-By header was found, reducing one common source of backend fingerprinting information. The x-cache response header indicates a CDN or caching proxy in the delivery path. No obvious internal addresses or debug information were found in the headers. No CORS permission header was found, so browsers normally restrict cross-origin script access.

Technology Stack Analysis

The public page identifies jQuery, Google Tag Manager without precise versions, leaving fewer clues for version-specific scanning.

Search and Social Sharing

The title has 72 characters and may be truncated in search results. Twitter Card metadata is configured. A meta description is present, with 142 characters. The observed directives allow indexing and link following. No Generator meta tag is publicly exposed.
