Website Overview
An established domain and managed infrastructure suggest continuity of operations and may support dependable delivery, although neither guarantees service quality. Page metadata, canonical configuration and social previews work together to provide more consistent search and sharing presentation.
Domain and Registration
Registered in 1996, this domain has about 30 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 domain uses the common .com extension, which is not an independent safety signal.
DNS and Email
Nameservers are provided by worldnic.com, indicating managed DNS hosting. MX records point to the Mimecast email service. No CNAME was found; the observed records resolve directly to addresses. SPF and DMARC are configured. DKIM status is unknown. TXT records include verification markers for Google. Such markers may also remain after a service stops being used.
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
No X-Powered-By header was found, reducing one common source of backend fingerprinting information. All six checked browser-security headers are present. Their effectiveness still depends on the policy values and application behavior. 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 WordPress, Alpine.js, Google Tag Manager, 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 title has 60 characters, within a common display range. A meta description is present, with 159 characters. The observed directives allow indexing and link following.
