Website Overview
Identifiable technologies and additional version or configuration signals make the service easier to fingerprint, which may help targeted scanners narrow their checks. 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 1995, this domain has about 31 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 registrar is Gandi SAS, a widely used domain service provider. The domain uses the common .com extension, which is not an independent safety signal.
DNS and Email
The lowest TTL is 9 seconds, supporting rapid record changes at the cost of more frequent lookups. Nameservers are provided by Amazon Route 53, indicating managed DNS hosting. MX records point to the Google Workspace email service. CAA records restrict which certificate authorities are authorized to issue certificates. No CNAME was found; the observed records resolve directly to addresses.
TLS and Certificates
The certificate uses an RSA 2048-bit public key, offering broad client compatibility. The server supplied a complete certificate chain. No organization name is present in the certificate; the available fields are consistent with domain validation. The certificate was issued by Let's Encrypt, commonly associated with automated certificate services. The certificate's total validity is about 89 days, consistent with a short renewal cycle.
HTTP and Browser Security
The response lacks these common security headers: CSP. No X-Powered-By header was found, reducing one common source of backend fingerprinting information. The x-cache, x-served-by, via response header indicates a CDN or caching proxy in the delivery path. No obvious internal addresses or debug information were found in the headers. The Server header identifies nginx without an exact version.
Technology Stack Analysis
The public page identifies WordPress 7.0.4, Google Tag Manager, Fastly, nginx, with exact versions exposed for 1 technologies. These details can narrow vulnerability checks, although exposure alone is not a vulnerability.
Search and Social Sharing
The Generator tag identifies WordPress 7.0.4, making the publishing system easier to fingerprint. Twitter Card metadata is configured. The page declares 2 language or regional alternatives using hreflang. The title has 53 characters, within a common display range. A meta description is present, with 153 characters.
