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

The vdek-Kliniklotse website is an official healthcare information portal operated by the Verband der Ersatzkassen e.V. (vdek), providing a comprehensive search platform for hospitals across Germany. It leverages official quality reports to offer patients and their families detailed information about hospital services, specialties, and quality metrics. The site also offers additional resources such as checklists for hospital stays and links to related vdek services like care and doctor locators. The target audience is primarily German-speaking patients seeking reliable healthcare information. Technically, the website employs a modern frontend stack including Bootstrap, jQuery, and FontAwesome, ensuring good mobile responsiveness and accessibility. It uses Matomo analytics with user consent, reflecting a privacy-conscious approach. The site is well-structured with clear navigation and professional design, although no CMS or hosting provider details are explicitly identified. From a security perspective, the site uses HTTPS and implements a detailed cookie consent mechanism with categories for necessary and statistical cookies. However, it lacks explicit security headers and published security policies or incident response contacts. No vulnerabilities or exposed sensitive data were detected in the content. The WHOIS data indicates a consistent and legitimate domain registration aligned with the business entity. Overall, the website presents a trustworthy, professional, and privacy-compliant platform with good content quality and technical implementation. Strategic improvements could include enhancing security headers, publishing security policies, and adding vulnerability disclosure information to further strengthen trust and compliance.

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

2 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.

  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

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 vdek-Kliniklotse is positioned as a key healthcare information service in Germany, operated by a reputable health insurance association. Its competitive advantage lies in providing official, quality-assured hospital data combined with user-friendly search and comparison tools. The business model focuses on serving patients and healthcare consumers with free access to comprehensive hospital information, supported by the association's mandate. Revenue streams are likely indirect, through association funding rather than direct monetization. The site integrates with a broader ecosystem of vdek services, enhancing user engagement and cross-service referrals. Growth indicators include regular updates with the latest quality reports and expanding search features. Partnerships with official bodies and related healthcare portals reinforce its market presence and credibility.

Security posture

The website demonstrates a moderate to good security posture with HTTPS enforced and a robust cookie consent mechanism respecting user privacy. The use of session cookies and controlled third-party content loading indicates attention to secure session management and privacy. However, the absence of key HTTP security headers (such as CSP, HSTS, X-Frame-Options) and lack of published security policies or incident response contacts represent gaps in security maturity. No security.txt or vulnerability disclosure mechanisms were found, limiting transparency for security researchers. The site does not expose sensitive data or use vulnerable libraries in the visible content. Overall, the security posture is adequate for an informational portal but could be enhanced by adopting best practices in HTTP headers and incident response readiness.

Recommendations

  1. Implement comprehensive HTTP security headers including Content Security Policy (CSP), HTTP Strict Transport Security (HSTS), X-Frame-Options, and X-XSS-Protection.
  2. Publish a clear security policy page outlining security commitments and practices.
  3. Establish and publicize an incident response contact channel (e.g., security@ or abuse@ email) for vulnerability reporting.
  4. Add a security.txt file at the root domain to facilitate responsible vulnerability disclosure.
  5. Regularly audit and update third-party scripts and libraries to mitigate potential vulnerabilities.

Technical notes

Notes

The website uses a modern and widely supported technology stack with Bootstrap 5, jQuery 3.7.1, FontAwesome 6.7.2, and Popper.js for UI components and responsiveness. The site is mobile-optimized and accessible, with semantic HTML and ARIA roles for dialogs and navigation. Performance is moderate, with no obvious heavy resources or blocking scripts. SEO is supported by proper meta tags including description, keywords, and viewport settings. The site uses Matomo analytics with explicit user consent, aligning with privacy best practices. No CMS or hosting provider details are exposed, but DNS name servers indicate professional hosting. The site uses modal dialogs for contact forms, enhancing user experience. Overall, the technical implementation is solid with room for improvement in security headers and potential CMS identification.
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.
