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 2010, this domain has about 16 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 NameCheap, Inc., 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 he.net, indicating managed DNS hosting. MX records point to the Google Workspace email service. CAA records restrict which certificate authorities are authorized to issue certificates. 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 4096-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
X-Powered-By exposes backend information: Pure Awesomeness. All six checked browser-security headers are present. Their effectiveness still depends on the policy values and application behavior. 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 Sentry 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 52 characters, within a common display range. A meta description is present, with 131 characters. The observed directives allow indexing and link following.
