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 Consent Banner found

      GDPR requires explicit consent for non-essential cookies

      What to do: Implement a cookie consent banner that appears on first visit

  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

The practice targets local families in Lübeck and surrounding areas, positioning itself as a trusted pediatric healthcare provider with a broad service offering and long-standing presence. The business model is service-based healthcare, relying on patient visits and medical consultations. The website supports patient engagement with detailed information on acute and appointment-based consultations, vaccination programs, and practice news. The absence of advertising and minimal tracking indicates a focus on patient privacy and trust. The practice collaborates with other pediatricians for coverage during vacations and special cases, indicating a networked approach to healthcare delivery. Growth indicators include active communication of practice updates and Covid-19 vaccination availability. The website's professional presentation and comprehensive content support competitive advantage in the local healthcare market.

Security posture

The website demonstrates a mature security posture with HTTPS enforced and no visible exposure of sensitive data. Cookie consent is managed via a GDPR-compliant banner, and no vulnerable or outdated libraries were detected in the HTML content. However, the absence of explicit security headers such as Content-Security-Policy and X-Frame-Options suggests room for improvement. No public security policy or incident response contact information is provided, which could be enhanced to improve transparency and readiness. The site does not expose any forms that collect sensitive data without consent mechanisms. Overall, the security posture is solid for a healthcare website but could benefit from additional hardening and documented policies.

Recommendations

  1. Implement security headers like Content-Security-Policy, X-Frame-Options, and X-XSS-Protection to enhance protection against common web attacks.
  2. Publish a security policy and incident response contact information to improve transparency and preparedness.
  3. Regularly audit and update WordPress plugins and themes to mitigate vulnerabilities.
  4. Consider adding a security.txt file to facilitate responsible vulnerability disclosure.
  5. Maintain and monitor cookie consent mechanisms to ensure ongoing GDPR compliance.

Technical notes

Notes

The website is built on WordPress with Elementor as the page builder, leveraging modern front-end technologies such as jQuery, Swiper for sliders, and LazySizes for image lazy loading. Autoptimize is used for CSS and JS optimization, improving load times. The site is responsive and mobile-friendly, with good SEO metadata including Open Graph and JSON-LD structured data. Performance is moderate, with caching and minification in place. Hosting provider details are not explicitly disclosed. Accessibility is basic but could be improved with more ARIA roles and semantic HTML. Overall, the technical infrastructure supports a professional and user-friendly experience with opportunities for further optimization and security enhancements.
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.
