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 1995, this domain has about 31 years of history. That suggests continuity, although ownership and purpose may have changed. The domain uses the common .org extension, which is not an independent safety signal.

DNS and Email

Nameservers are provided by siteground.net, indicating managed DNS hosting. MX records point to the Google Workspace 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 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 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: HSTS, CSP, Referrer-Policy, Permissions-Policy, clickjacking protection. 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 nginx without an exact version. No explicit CDN or WAF marker was found in the response headers.

Technology Stack Analysis

The public page identifies Site Kit by Google 1.190.0, WordPress, jQuery, Bootstrap, Google Analytics, nginx, 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 title has 106 characters and may be truncated in search results. The meta description has 200 characters and may be shortened in search results. The Generator tag identifies Site Kit by Google 1.190.0, making the publishing system easier to fingerprint. Open Graph is partially configured; og:title, og:description, og:type is missing. A viewport declaration is present, providing a basis for mobile layout.
