Website Overview

Several search or sharing settings need attention. Together they may make snippets, preview images or preferred URLs less consistent across platforms. An active inbound-mail setup with incomplete authentication may leave the domain more open to impersonation. Provider hosting alone does not close that gap.

Domain and Registration

The domain uses the common .de 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 hostsharing.net, indicating managed DNS hosting. MX records point to the hostsharing.net 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 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 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: 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. 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 Apache without precise versions, leaving fewer clues for version-specific scanning.

Search and Social Sharing

The meta description has 169 characters and may be shortened in search results. No homepage canonical URL was detected. If duplicate URLs exist, consolidation may be less explicit. No Open Graph metadata was detected, so social previews may depend on platform inference. The title has 64 characters, within a common display range. The observed directives allow indexing and link following.
