Website Overview

Identifiable technologies and additional version or configuration signals make the service easier to fingerprint, which may help targeted scanners narrow their checks. 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 2007, this domain has about 19 years of history. That suggests continuity, although ownership and purpose may have changed. The registrar, MarkMonitor 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

MX records exist, but SPF, DKIM and DMARC were not detected. Protection against domain impersonation may be incomplete. Nameservers are provided by Cloudflare, indicating managed DNS hosting. MX records point to the Google Workspace email service. No CNAME was found; the observed records resolve directly to addresses. 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

The response lacks these common security headers: CSP, Permissions-Policy. No X-Powered-By header was found, reducing one common source of backend fingerprinting information. The cf-ray, x-cache 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 Site Kit by Google 1.185.0, WordPress, Cloudflare, with exact versions exposed for 1 technologies. These details can narrow vulnerability checks, although exposure alone is not a vulnerability.

Search and Social Sharing

The Generator tag identifies Site Kit by Google 1.186.0, making the publishing system easier to fingerprint. 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 142 characters.
