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 2009, this domain has about 17 years of history. That suggests continuity, although ownership and purpose may have changed. The registrar, CSC Corporate Domains, Inc., specializes in corporate domain and brand management, suggesting attention to domain asset protection. 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 Cloudflare, indicating managed DNS hosting. MX records point to the Google Workspace email service. CAA records restrict which certificate authorities are authorized to issue certificates. No CNAME was found; the observed records resolve directly to addresses. 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: X-Content-Type-Options, Referrer-Policy, 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 jQuery, 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 30 characters, within a common display range. A meta description is present, with 47 characters. The observed directives allow indexing and link following.
