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

4 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

    • High

      No Cookie Consent Banner found

      GDPR requires explicit consent for non-essential cookies

      What to do: Implement a cookie consent banner that appears on first visit

  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 Protocols Supported

      Server supports weak protocols: TLSv1.1

      What to do: Disable TLS 1.0, TLS 1.1, and all SSL versions

      • CWE-327
      • OWASP A04:2025
      • ASVS V12.1.1

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

The Knappschaft is positioned as a key statutory health insurance fund in Germany, serving a large customer base with comprehensive healthcare and insurance services. Its government affiliation provides a competitive advantage and trustworthiness. The business model focuses on statutory health insurance, digital health services, and customer support. The website reflects a mature digital ecosystem with partnerships for health courses and online health coaching. Growth indicators include digital service expansion and extensive preventive care offerings. The partnership ecosystem includes official government and health portals, enhancing service reach and credibility.

Security posture

The website exhibits a mature security posture with enforced HTTPS, GDPR-compliant cookie consent via Usercentrics, and use of Matomo analytics with minimal tracking. No critical vulnerabilities or exposed sensitive information were detected in the HTML content. However, explicit security headers like Content-Security-Policy and X-Frame-Options are not clearly present and should be implemented to enhance protection. Incident response and security policy pages are not found, which could improve transparency and readiness. Overall, the site balances user privacy and security effectively but can enhance header security and incident communication.

Recommendations

  1. Implement and explicitly declare security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  2. Publish a dedicated security policy and incident response page to improve transparency and user trust.
  3. Regularly audit third-party scripts and libraries for vulnerabilities and update them promptly.
  4. Enhance performance optimization to improve loading speed and user experience.
  5. Continue to maintain and improve GDPR compliance and privacy transparency.

Technical notes

Notes

The website is built on the Government Site Builder CMS, a specialized platform for government entities, ensuring compliance and structured content management. It uses Matomo for privacy-friendly analytics and Usercentrics for consent management, reflecting a modern approach to privacy and data protection. The site employs responsive CSS stylesheets for excellent mobile optimization and accessibility features. JavaScript is loaded asynchronously to improve performance. Hosting details are not explicit, but multiple name servers indicate a stable infrastructure. Performance is moderate, with opportunities for optimization. The technical stack is modern and appropriate for a government health insurance provider.
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.
