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 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 60 seconds, supporting rapid record changes at the cost of more frequent lookups. Nameservers are provided by Amazon Route 53, indicating managed DNS hosting. DNS and provider evidence indicate traffic passes through the Cloudflare CDN, which may support caching and traffic distribution. MX records point to the Google Workspace email service. CAA records restrict which certificate authorities are authorized to issue certificates.
TLS and Certificates
The public key uses EC with 256 bits. 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, Referrer-Policy, Permissions-Policy. Debug-related headers are present: x-trace-id. Check whether they are needed in production. No X-Powered-By header was found, reducing one common source of backend fingerprinting information. The cf-ray response header indicates a CDN or caching proxy in the delivery path. The Server header identifies cloudflare without an exact version.
Technology Stack Analysis
The public page identifies Google Tag Manager, Cloudflare without precise versions, leaving fewer clues for version-specific scanning.
Search and Social Sharing
The meta description has 169 characters and may be shortened in search results. Open Graph is partially configured; og:title, og:description is missing. Twitter Card metadata is configured. The title has 57 characters, within a common display range. The observed directives allow indexing and link following.
