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 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, Microsoft. Such markers may also remain after a service stops being used.
TLS and Certificates
The certificate issuer is Sectigo Limited, a commercial certificate authority. The certificate uses an RSA 2048-bit public key, offering broad client compatibility. 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 is valid for about 198 days in total, with 164 days remaining.
HTTP and Browser Security
The checked browser-security headers were not detected, leaving fewer explicit browser-side safeguards. No X-Powered-By header was found, reducing one common source of backend fingerprinting information. No obvious internal addresses or debug information were found in the headers. The Server header identifies Apache without an exact version. No explicit CDN or WAF marker was found in the response headers.
Technology Stack Analysis
The public page identifies jQuery, Apache without precise versions, leaving fewer clues for version-specific scanning.
Search and Social Sharing
The title has 87 characters and may be truncated in search results. The meta description has 210 characters and may be shortened in search results. No Open Graph metadata was detected, so social previews may depend on platform inference. The observed directives allow indexing and link following. No Generator meta tag is publicly exposed.
