Website Overview
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 2002, this domain has about 24 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 50 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 Microsoft 365 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 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 within the Amazon cloud or CDN ecosystem. The certificate is valid for about 197 days in total, with 105 days remaining.
HTTP and Browser Security
The checked browser-security headers were not detected, leaving fewer explicit browser-side safeguards. CORS permits any origin to read this response. This is common for public resources; sensitive responses need narrower handling. No X-Powered-By header was found, reducing one common source of backend fingerprinting information. The x-cache, via response header indicates a CDN or caching proxy in the delivery path. No obvious internal addresses or debug information were found in the headers.
Technology Stack Analysis
The public page identifies Amazon CloudFront without precise versions, leaving fewer clues for version-specific scanning.
