Website Overview
Identifiable technologies and additional version or configuration signals make the service easier to fingerprint, which may help targeted scanners narrow their checks. Page metadata, canonical configuration and social previews work together to provide more consistent search and sharing presentation.
Domain and Registration
The domain has about 5 years of registration history; its current configuration provides more context than age alone. The domain uses the common .app 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 second-ns.com, indicating managed DNS hosting. MX records point to the your-server.de email service. No CNAME was found; the observed records resolve directly to addresses. TXT records include verification markers for Google. 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 checked browser-security headers were not detected, leaving fewer explicit browser-side safeguards. 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 identifies Apache without an exact version. No explicit CDN or WAF marker was found in the response headers.
Technology Stack Analysis
The public page identifies WordPress 7.1.4, Apache, with exact versions exposed for 1 technologies. These details can narrow vulnerability checks, although exposure alone is not a vulnerability.
Search and Social Sharing
The Generator tag identifies WordPress 7.1.4, making the publishing system easier to fingerprint. Twitter Card metadata is configured. JSON-LD includes Organization data, helping describe the organization as an entity. The title has 41 characters, within a common display range. A meta description is present, with 112 characters.
