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. 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 Strict-Transport-Security header

      Forces HTTPS connections

      What to do: Add "Strict-Transport-Security: max-age=31536000; includeSubDomains; preload"

      • CWE-319
      • OWASP A04:2025
      • ASVS V3.4.1
    • High

      Missing X-Frame-Options header

      Prevents clickjacking attacks

      What to do: Add "X-Frame-Options: DENY" or "X-Frame-Options: SAMEORIGIN"

    • 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';…

  2. GDPR outside view

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

    • 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.

Technical appendix

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

Business context

Business profile

MediData AG occupies a solid position in the Swiss healthcare IT market, providing essential digital infrastructure for data exchange among healthcare providers, insurers, and patients. Its business model revolves around network services and software solutions that streamline administrative processes and ensure compliance with evolving regulations. The company benefits from long-standing industry experience, a large network of over 20,000 connections, and partnerships with software vendors. Revenue streams likely include subscription or usage fees for network access and value-added services. The company actively communicates through blogs and events, indicating engagement with the healthcare community and thought leadership. Its certifications and transparent contact details enhance credibility and customer trust.

Security posture

MediData demonstrates a mature security posture with ISO 27001 and VDSZ certifications, HTTPS enforcement, and comprehensive security headers. The presence of a secure document submission service (SubmitBox) and cookie consent management reflects attention to data protection and privacy compliance. However, the absence of a public vulnerability disclosure policy or security.txt file and lack of explicit incident response contact information are gaps that could be addressed to improve transparency and readiness. No vulnerabilities or exposed sensitive data were detected in the website content or scripts. Overall, the security culture appears strong, aligned with industry best practices for healthcare data protection.

Recommendations

  1. Publish a vulnerability disclosure policy or security.txt file to facilitate responsible reporting.
  2. Add explicit incident response contact channels (e.g., security@ or abuse@ email addresses) on the website.
  3. Enhance accessibility features to meet higher compliance standards and improve user experience.
  4. Consider creating a terms of service page to clarify user agreements and legal conditions.
  5. Regularly review and update third-party scripts and analytics tools to mitigate potential vulnerabilities.

Technical notes

Notes

The website is powered by TYPO3 CMS, a robust open-source content management system, indicating a stable and scalable infrastructure. It uses modern JavaScript libraries and integrates analytics tools such as Matomo and Google Tag Manager, balancing tracking needs with privacy compliance via ConsentManager. The site is mobile-optimized with good navigation clarity and SEO practices. Performance is moderate, with potential for optimization in loading speed. Hosting details are not explicitly identified, but the presence of multiple external domains for analytics and consent management is noted. The technical setup supports the business goals effectively but could benefit from enhanced accessibility 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.
