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

5 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. Security headers

    Security headers are instructions your web server sends to every visitor’s browser. Missing ones leave visitors more exposed to attacks such as clickjacking and injected scripts.

    • High

      Missing Content-Security-Policy header

      Controls resources the browser is allowed to load

      What to do: Implement a Content-Security-Policy appropriate for your application

      • ASVS V3.4.3
      • OWASP Secure Headers: OWASP Secure Headers Project recommends Content-Security-Policy: default-src 'self'; form-action 'self'; base-uri 'self'; object-src 'none';…
  3. 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 hkk Krankenkasse holds a competitive position in the German healthcare insurance market, emphasizing cost advantages and service quality. Their business model revolves around statutory health insurance supplemented by additional insurance products and digital health services. The company leverages partnerships, such as with LVM Versicherung, to extend service reach. Their marketing and communication strategies include awards and certifications to build trust. The target market is broad, covering various insured groups in Germany. The digital infrastructure supports customer engagement through calculators, apps, and online forms, indicating a focus on digital transformation and customer convenience.

Security posture

The website exhibits a solid security posture with enforced HTTPS, presence of key security headers, and integration of a consent management platform to comply with GDPR. No exposed sensitive data or vulnerable libraries were detected in the analysis. However, the absence of a publicly available security policy or incident response contact limits transparency in security governance. There is also no visible vulnerability disclosure policy or security.txt file. Overall, the security maturity is good but could be enhanced by publishing dedicated security documentation and incident response procedures.

Recommendations

  1. Publish a dedicated security policy page outlining security practices and commitments.
  2. Provide clear incident response contact information to facilitate reporting of security issues.
  3. Implement and publicly disclose a vulnerability disclosure policy or security.txt file.
  4. Regularly review and audit third-party scripts and libraries for security vulnerabilities.
  5. Enhance transparency on data retention and processing policies to strengthen privacy compliance.

Technical notes

Notes

The website is powered by TYPO3 CMS, a robust and widely used content management system, indicating a stable and scalable infrastructure. The use of modern JavaScript, CSS, and font loading techniques suggests attention to performance and user experience. Integration with Usercentrics for consent management and Google Tag Manager for analytics shows adherence to privacy and marketing best practices. The site is mobile-optimized and accessible, with good SEO metadata and structured navigation. Performance is moderate, with potential for optimization in asset loading and caching strategies. No hosting provider details were explicitly found, but the domain uses multiple authoritative name servers, indicating reliable DNS management.
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.
