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 1996, this domain has about 30 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 .org extension, which is not an independent safety signal.

DNS and Email

The lowest TTL is 60 seconds, supporting rapid record changes at the cost of more frequent lookups. Nameservers are provided by Amazon Route 53, indicating managed DNS hosting. MX records point to the Google Workspace email service. No CNAME was found; the observed records resolve directly to addresses. SPF and DMARC are configured. DKIM status is unknown.

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 175 days remaining.

HTTP and Browser Security

The response lacks these common security headers: Permissions-Policy. 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. Cookie security attributes are unknown. No explicit CDN or WAF marker was found in the response headers.

Technology Stack Analysis

The public page identifies Google Analytics without precise versions, leaving fewer clues for version-specific scanning.

Search and Social Sharing

No homepage canonical URL was detected. If duplicate URLs exist, consolidation may be less explicit. Open Graph is partially configured; og:title, og:type is missing. The title has 30 characters, within a common display range. A meta description is present, with 99 characters. The observed directives allow indexing and link following.
