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 1999, this domain has about 27 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 GoDaddy.com, LLC, 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 GoDaddy, indicating managed DNS hosting. MX records point to the Microsoft 365 email service. SPF and DMARC are configured. DKIM status is unknown. DNSSEC signatures were not detected, so this additional DNS authenticity protection is not confirmed. The lowest observed DNS TTL is 300 seconds.
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
The response lacks these common security headers: HSTS, CSP, 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. 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.
Technology Stack Analysis
The public page identifies Cloudflare without precise versions, leaving fewer clues for version-specific scanning.
Search and Social Sharing
The meta description has 199 characters and may be shortened in search results. Twitter Card metadata is configured. JSON-LD includes Product or Offer data, potentially supporting eligible product search features. The title has 65 characters, within a common display range. The observed directives allow indexing and link following.
