Website Overview
Page metadata, canonical configuration and social previews work together to provide more consistent search and sharing presentation.
Domain and Registration
Transfer-protection status is present, helping reduce the risk of unauthorized domain transfers. The domain has about 1 years of registration history; its current configuration provides more context than age alone. The registrar is Cloudflare, Inc., a widely used domain service provider. The domain uses the common .com extension, which is not an independent safety signal.
DNS and Email
Nameservers are provided by Cloudflare, indicating managed DNS hosting. No CNAME was found; the observed records resolve directly to addresses. No MX record was found. A conventional explicit inbound-mail route is not configured. TXT records include verification markers for Google. Such markers may also remain after a service stops being used. DNSSEC signatures were not detected, so this additional DNS authenticity protection is not confirmed.
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 within the Google Trust Services cloud or CDN ecosystem. The certificate's total validity is about 90 days, consistent with a short renewal cycle.
HTTP and Browser Security
X-Powered-By exposes backend information: Next.js. The response lacks these common security headers: CSP, Permissions-Policy. 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 Next.js, Cloudflare without precise versions, leaving fewer clues for version-specific scanning.
Search and Social Sharing
Twitter Card metadata is configured. JSON-LD includes Organization data, helping describe the organization as an entity. The page declares 9 language or regional alternatives using hreflang. The title has 21 characters, within a common display range. A meta description is present, with 126 characters.
