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 2005, this domain has about 21 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. SPF and DMARC are configured. DKIM status is unknown.
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, Permissions-Policy. 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. No obvious internal addresses or debug information were found in the headers. The Server header identifies cloudflare without an exact version.
Technology Stack Analysis
The public page identifies React, Google Analytics, Cloudflare 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. Twitter Card metadata is configured. The title has 12 characters, within a common display range. A meta description is present, with 125 characters. No Generator meta tag is publicly exposed.
