Website Overview
Identifiable technologies and additional version or configuration signals make the service easier to fingerprint, which may help targeted scanners narrow their checks. 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 2018, this domain has about 8 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 .io extension, which is not an independent safety signal.
DNS and Email
The observed email authentication setup is incomplete: DMARC is missing. Nameservers are provided by Cloudflare, indicating managed DNS hosting. MX records point to the registrar-servers.com email service. No CNAME was found; the observed records resolve directly to addresses. 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 90 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. The cf-ray response header indicates a CDN or caching proxy in the delivery path. No obvious internal addresses or debug information were found in the headers. The Server header identifies cloudflare without an exact version.
Technology Stack Analysis
The public page identifies Docusaurus 3.10.2, Cloudflare, Netlify, with exact versions exposed for 1 technologies. These details can narrow vulnerability checks, although exposure alone is not a vulnerability.
Search and Social Sharing
No homepage meta description was detected, leaving snippet selection more dependent on page text. The Generator tag identifies Docusaurus v3.10.2, making the publishing system easier to fingerprint. Open Graph is partially configured; og:description, og:type is missing. Twitter Card metadata is configured. The page declares 10 language or regional alternatives using hreflang.
