This scan rated NIS2 with an earlier keyword method that is no longer shown; rescan for the per-article view. Risk management, continuity, supply chain, training, MFA, management oversight (Art. 20) and incident reporting (Art. 23) need internal evidence, and Guard cannot tell whether NIS2 applies to this organisation.

GDPR is indicative only, based on publicly visible signals: Articles 7, 12, 13 and 32 of Regulation (EU) 2016/679 and Article 5(3) of the ePrivacy Directive. Not a certification or legal assessment.

Priority findings

3 findings rated critical or high. Fix these first.

  1. GDPR outside view

    These are the privacy signals visitors and data protection authorities look for under GDPR.

    • Critical

      EU business without adequate privacy measures

      EU businesses are subject to strict GDPR requirements

      What to do: Implement comprehensive GDPR compliance including privacy policy, cookie consent, and data protection measures

    • High

      No Cookie Policy found

      GDPR requires clear information about cookie usage

      What to do: Add a dedicated cookie policy explaining cookie usage and purposes

  2. SSL/TLS

    TLS encrypts the connection and proves the site is really yours. Weak or expiring certificates trigger browser warnings and put traffic at risk.

    • High

      Weak SSL Key Length

      SSL certificate uses 384-bit key, which is considered weak

      What to do: Use at least 2048-bit RSA or 256-bit ECC key

      • CWE-326
      • OWASP A04:2025
      • Mozilla TLS: Mozilla Server Side TLS 6.0 intermediate: rsa_key_size 2048

Results by check

Each check with its score, findings and the evidence it collected.

How this score is calculated

The security score runs 0–100, higher is better. It is the plain average of the security checks that completed in this scan, each counted equally. A check that could not run is left out: it counts neither as a pass nor as a fail.

Not counted

  • NIS2 outside view: Re-weights evidence from the TLS, email, DNS, network and hygiene checks, so counting it would count that evidence twice. Shown on its own.
  • OffSeq Observations: An AI reading of the site, useful context but not reproducible evidence. Shown on its own.

Findings that cap the score at 49

Each of these is serious on its own, so while any is present the site cannot rate better than high risk, however good the other checks are.

  • The certificate is not trusted by browsers
  • The website is not served over HTTPS
  • A database, remote desktop, file-sharing or Telnet service is reachable from the internet
  • The page loads a script from a compromised source
  • The domain registration has expired
  • SPF authorises every server to send mail as the domain

Partial scans

When the site blocks Guard or most checks cannot run, the score covers only the checks that ran (usually DNS and email), is capped at 75 and is shown as partial, without a risk level.

Technical appendix

Business context, site observations and technical notes gathered during the scan, and the standards behind each reference.

Business context

Business profile

Geizhals.de holds a strong market position as a trusted price comparison platform in German-speaking countries, particularly Germany and Austria. Its business model revolves around affiliate marketing and providing consumers with detailed product information and price comparisons. The company leverages partnerships with merchants and advertisers to generate revenue. The platform's target audience includes price-conscious consumers and tech-savvy shoppers. The website's consistent branding, comprehensive content, and user-friendly features contribute to its competitive advantage. The sister domain geizhals.at serves the Austrian market, indicating a regional expansion strategy. While no explicit certifications or legal company details were found, the platform's mature infrastructure and compliance with GDPR indicate a professional operation.

Security posture

The website exhibits a mature security posture with HTTPS enforced and multiple security headers implemented, including Content-Security-Policy and Strict-Transport-Security. The use of CSRF tokens and integrity attributes on scripts further strengthens security. The cookie consent mechanism complies with GDPR requirements, ensuring user privacy. However, the absence of a published security policy, incident response contacts, and vulnerability disclosure mechanisms represents gaps in transparency and readiness. No vulnerabilities or exposed sensitive data were detected in the HTML content. The WHOIS data is consistent and does not raise suspicion. Overall, the security posture is strong but could be improved by adding explicit security governance documentation and communication channels.

Recommendations

  1. Publish a dedicated security policy page outlining security practices and commitments.
  2. Provide clear incident response contact information, such as security@ or abuse@ email addresses.
  3. Implement and publish a security.txt file to facilitate vulnerability disclosures.
  4. Enhance transparency by including company contact emails and phone numbers on the website.
  5. Regularly review and update third-party scripts and dependencies to avoid vulnerabilities.

It integrates third-party services such as Matomo for analytics and Google DoubleClick for advertising. The site is optimized for performance and mobile devices, with good accessibility and SEO practices observed. The hosting environment appears stable with no signs of CDN abuse or performance bottlenecks. The use of integrity attributes on scripts indicates attention to supply chain security.

Standards and sources

Reference chips under each finding point to the standard, regulation or specification the finding relates to. They are taken from the official datasets below and mapped conservatively: a finding with no defensible link shows none. NIS2 and GDPR references mark where a finding is relevant evidence, not a compliance verdict. Implementing Regulation (EU) 2024/2690 binds digital infrastructure and digital service providers; for other entities it is the most detailed public reading of the Article 21 measures. WCAG, EN 301 549, European Accessibility Act and Web Accessibility Directive references name the requirement an automated accessibility rule relates to; they are not a conformance verdict.
