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

6 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. 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

  3. 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 X-Frame-Options header

      Prevents clickjacking attacks

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

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 organization holds a strong market position in the German healthcare sector, particularly in cardiology and vascular medicine. It benefits from partnerships and affiliations with multiple hospitals and healthcare providers within the Immanuel Albertinen Diakonie network. The business model is non-profit, focusing on patient care, research, and education. The website links extensively to partner and subsidiary domains, indicating a broad ecosystem. The target audience includes patients, healthcare professionals, and the general public interested in cardiovascular health. The presence of social media channels and regular news updates suggests active engagement and transparency. No direct revenue streams are visible on the site, consistent with a non-profit healthcare provider.

Security posture

The website enforces HTTPS and uses a cookie consent banner with opt-in/out options, demonstrating compliance with privacy regulations. It employs a consent overlay for embedding YouTube videos to protect user privacy. No critical vulnerabilities or exposed sensitive data were detected in the HTML content. However, the absence of published security policies, incident response contacts, and vulnerability disclosure mechanisms indicates room for improvement in transparency and readiness. Security headers were not explicitly detected in the provided data, suggesting potential enhancement opportunities. Overall, the security posture is solid but could benefit from formal documentation and additional HTTP security headers.

Recommendations

  1. Publish a formal security policy and incident response information on the website to improve transparency and user trust.
  2. Implement and expose a vulnerability disclosure policy or security.txt file to facilitate responsible reporting of security issues.
  3. Enhance HTTP security headers such as Content-Security-Policy, Strict-Transport-Security, and X-Frame-Options to strengthen defense-in-depth.
  4. Regularly audit and update third-party scripts and libraries to mitigate risks from vulnerabilities.
  5. Maintain and document data retention policies and privacy practices clearly to reinforce GDPR compliance.

Technical notes

Notes

The website is built on TYPO3 CMS, a mature and widely used content management system, indicating a stable and scalable infrastructure. The use of modern HTML5, CSS, and JavaScript ensures compatibility and responsiveness across devices. The site includes accessibility features such as skip navigation links and ARIA labels, enhancing usability for users with disabilities. Performance is moderate, with optimized images and compressed assets, though no explicit hosting provider information was found. SEO is supported by proper meta tags, Open Graph, and Twitter card metadata. The cookie consent mechanism and privacy overlays demonstrate attention to privacy and user experience. Overall, the technical implementation is robust and aligns with best practices for healthcare websites.
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.
