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 2017, this domain has about 9 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 registrar is GoDaddy.com, LLC, a widely used domain service provider. The domain uses the common .org extension, which is not an independent safety signal.
DNS and Email
Nameservers are provided by dns-noc.net, 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. TXT records include verification markers for Microsoft. Such markers may also remain after a service stops being used.
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: Referrer-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. The Server header contains the custom value noc.org/cdn. No explicit CDN or WAF marker was found in the response headers.
Technology Stack Analysis
The public page identifies jQuery, Bootstrap 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 45 characters, within a common display range. A meta description is present, with 144 characters. The observed directives allow indexing and link following.
