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 2012, this domain has about 14 years of history. That suggests continuity, although ownership and purpose may have changed. The registrar, Nom-iq Ltd. dba COM LAUDE, specializes in corporate domain and brand management, suggesting attention to domain asset protection. 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
Nameservers are provided by he.net, indicating managed DNS hosting. No CNAME was found; the observed records resolve directly to addresses. No MX record was found. A conventional explicit inbound-mail route is not configured. DNSSEC signatures were not detected, so this additional DNS authenticity protection is not confirmed. The lowest observed DNS TTL is 1800 seconds.
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 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, x-served-by, 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 Quarkus Roq 2.0.5, Google Analytics, Fastly, 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 Quarkus Roq v2.0.5, making the publishing system easier to fingerprint. Open Graph is partially configured; og:description, og:image is missing. Twitter Card metadata is configured. The title has 19 characters, within a common display range.
