0–100, higher is better. How it is calculated

The GKV-Datenaustausch website is an official information portal operated by the GKV-Spitzenverband, the central association for statutory health insurance in Germany. It provides comprehensive and up-to-date information on electronic data exchange procedures and technical standards for healthcare providers, employers, and other stakeholders involved in the statutory health insurance system. The portal serves as a trusted resource for technical documentation, procedural guidance, and updates via RSS feeds, positioning itself as a key authoritative source in the healthcare data exchange domain. Technically, the website employs standard web technologies including JavaScript, jQuery, and Matomo analytics hosted on its own domain, reflecting a privacy-conscious approach to user tracking. The site is hosted on servers associated with ITSG, a recognized service provider for statutory health insurance IT services. The site demonstrates moderate performance and basic mobile optimization, with good accessibility and SEO practices. The presence of a cookie consent banner with granular options aligns with GDPR compliance requirements. From a security perspective, the site enforces HTTPS and uses secure cookie attributes, but lacks explicit security headers such as Content-Security-Policy or X-Frame-Options. No vulnerabilities or exposed sensitive data were detected. However, the absence of published security policies or incident response contacts suggests room for improvement in transparency and readiness. Overall, the security posture is solid but could be enhanced with additional best practices. The website is fully accessible without any WAF or blocking mechanisms, and the WHOIS data confirms the domain's legitimacy and consistency with the GKV-Spitzenverband organization. No suspicious patterns or privacy protections obscure the domain registration. The site does not contain any adult or questionable content and is suitable for a general audience. Strategic recommendations include publishing security and incident response policies, improving mobile optimization, and adding advanced security headers to strengthen the security posture further.

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. Email security

    SPF, DKIM and DMARC stop others sending email that looks like it comes from your domain, a common route to phishing and invoice fraud.

    • Critical

      No email authentication configured

      Domain is vulnerable to email spoofing

      What to do: Implement SPF, DKIM, and DMARC immediately

  2. 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

  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.

Business context

Business profile

The GKV-Datenaustausch portal operates within the healthcare and government sectors, serving as an essential information hub for statutory health insurance data exchange in Germany. Its market position is that of an authoritative and official source, backed by the GKV-Spitzenverband. The business model focuses on providing technical documentation, procedural guidance, and updates to healthcare providers, employers, and related entities. Revenue streams are not directly evident as the portal is likely funded by the statutory health insurance system. The target customer segments include healthcare providers, employers, software developers, and statutory health insurance institutions. The partnership ecosystem includes ITSG as the hosting and service provider. The portal's operations emphasize transparency, compliance, and technical accuracy, supporting the statutory health insurance infrastructure in Germany.

Security posture

The website demonstrates a mature security posture with mandatory HTTPS, secure cookie handling, and privacy-conscious analytics via Matomo. The cookie consent mechanism is well implemented, distinguishing necessary and statistics cookies with user opt-in. No exposed sensitive data or vulnerable libraries were detected. However, the absence of explicit security policies, incident response contacts, and advanced security headers indicates gaps in security transparency and defense-in-depth. Compliance with GDPR is evident through privacy policy and cookie consent. Incident response readiness and vulnerability disclosure mechanisms are not publicly documented, which could impact trust and responsiveness in case of security incidents. Overall, the site is secure but would benefit from enhanced security governance and communication.

Recommendations

  1. Publish a dedicated security policy page outlining security practices and compliance.
  2. Provide clear incident response contact information to improve transparency and readiness.
  3. Implement additional security headers such as Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security.
  4. Enhance mobile optimization to improve user experience on mobile devices.
  5. Consider publishing a vulnerability disclosure policy or security.txt file to encourage responsible reporting.

Technical notes

Notes

The website uses a custom or unknown CMS with standard web technologies including JavaScript, jQuery, and CSS. Hosting is provided by ITSG, a known service provider for statutory health insurance IT infrastructure. The site loads scripts asynchronously and defers non-critical JavaScript to improve performance. SEO is supported by appropriate meta tags and structured navigation. Accessibility features such as skip links and font size controls are implemented, indicating attention to usability. However, mobile optimization is basic and could be improved. No modern frontend frameworks or CMS platforms were detected, suggesting potential technical debt or opportunity for modernization. Overall, the technical infrastructure is stable and functional but could benefit from modernization and performance tuning.
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.
