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

8 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

    • High

      Forces HTTPS connections

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

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.

Breach exposure

Leaked credentials and lookalike domains from OffSeq Breach. The counts are free; the detailed lists are paid add-ons.

Dark web exposure

Add-on

Leaked records that mention herz-frankfurt.de, from OffSeq Breach.

Technical appendix

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

Business context

Business profile

The center operates in the healthcare sector, targeting patients, visitors, and medical professionals. Its business model revolves around specialized medical services within a university hospital framework. The presence of certifications and partnerships with entities like Deutsche Herzstiftung and Eintracht Frankfurt enhances its credibility and market position. The website supports recruitment and event promotion, indicating active engagement with the medical community. Revenue streams likely include patient services and research funding. The digital ecosystem is mature, with clear branding and consistent messaging.

Security posture

The website enforces HTTPS and uses a consent manager to comply with privacy regulations. Google Analytics is configured with IP anonymization, reflecting privacy awareness. However, no explicit security policy or incident response contact is published, which could be improved. Security headers are not explicitly detected in the provided data, suggesting room for enhancement. No vulnerabilities or exposed sensitive data were found. The security score is solid but could benefit from formalized policies and additional technical controls.

Recommendations

  1. Publish a dedicated security policy page outlining security practices and commitments.
  2. Provide clear incident response contact information for security issues.
  3. Implement and verify security headers such as Content-Security-Policy and X-Frame-Options.
  4. Consider adding a vulnerability disclosure policy or security.txt file to encourage responsible reporting.
  5. Maintain and regularly update privacy and cookie policies to reflect evolving regulations.

Technical notes

Notes

The website is built on Craft CMS 5.8.15, a modern and flexible content management system. It uses JavaScript and CSS assets efficiently with deferred loading for performance. The site is mobile-optimized with responsive images and accessibility features like skip links. SEO is supported by meta tags and Open Graph data. Hosting appears to be managed via domaincontrol.com (GoDaddy) DNS services. Performance is moderate, with potential for optimization in asset delivery and caching. No outdated or vulnerable libraries were detected. Overall, the technical infrastructure supports a professional and user-friendly experience.
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.
