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 20 seconds, supporting rapid record changes at the cost of more frequent lookups. Nameservers are provided by Akamai Edge DNS, indicating managed DNS hosting. MX records point to the fireeyegov.com email service. DNSSEC is enabled, allowing validating resolvers to authenticate signed DNS data. SPF and DMARC are configured. DKIM status is unknown.
TLS and Certificates
The certificate includes the organization field Centers For Disease Control and Prevention. 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 177 days remaining.
HTTP and Browser Security
The response lacks these common security headers: CSP, X-Content-Type-Options, Referrer-Policy, Permissions-Policy, clickjacking protection. 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 Bootstrap without precise versions, leaving fewer clues for version-specific scanning.
Search and Social Sharing
The canonical URL points to another host: https://www.atsdr.cdc.gov/index.html. Search engines may consolidate indexing signals there. Twitter Card metadata is configured. JSON-LD includes Organization data, helping describe the organization as an entity. The title has 56 characters, within a common display range. A meta description is present, with 55 characters.
