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 2003, this domain has about 23 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 easydns.com, indicating managed DNS hosting. MX records point to the Microsoft 365 email service. No CNAME was found; the observed records resolve directly to addresses. SPF and DMARC are configured. DKIM status is unknown. 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 89 days, consistent with a short renewal cycle.
HTTP and Browser Security
The response lacks these common security headers: CSP, X-Content-Type-Options, 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 WordPress, jQuery, Google Tag Manager, nginx 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 39 characters, within a common display range. A meta description is present, with 148 characters. The observed directives allow indexing and link following.
