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

The HNO Praxisklinik Aachen is a specialized medical clinic focused on the diagnosis and treatment of ear, nose, and throat (ENT) diseases, including allergology. The clinic operates with a small but professional team of qualified specialists and cooperates with certified allergy centers, positioning itself as a trusted regional healthcare provider. Their services include pediatric hearing tests, sleep medicine, and ambulatory diagnostics, catering to both statutory and private patients, including international clients from neighboring countries. Technically, the website is built on the Contao CMS with a modern but straightforward tech stack including jQuery and Leaflet.js, offering good mobile optimization and SEO practices. Security-wise, the site enforces HTTPS and includes a cookie consent mechanism, but lacks explicit security policies or incident response contacts. Overall, the site is professional, trustworthy, and privacy-conscious, with room for improvement in security transparency and accessibility.

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

  2. Network security

    Services reachable from the internet are the first thing attackers probe. Anything open that does not need to be should be closed.

    • Critical

      Critical Service Exposed: MySQL

      Port 3306 (MySQL) is publicly accessible - MySQL - Database server

      What to do: Immediately restrict access to MySQL using firewall or VPN

      • NIS2 21(2)(e)
      • IR 2024/2690 6.7.2(f): Implementing Regulation (EU) 2024/2690, Annex point 6.7.2(f): Network security
      • NIST CM-7: NIST SP 800-53 Rev. 5 CM-7: Least Functionality
      • NIST SC-7: NIST SP 800-53 Rev. 5 SC-7: Boundary Protection

  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 Strict-Transport-Security header

      Forces HTTPS connections

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

      • CWE-319

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 · found on this site
  • 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 clinic holds a solid market position as a specialized ENT and allergy center in Aachen, Germany. Its competitive advantages include certified cooperation with allergy centers and a comprehensive range of diagnostic and therapeutic services. The business model focuses on outpatient medical services with revenue streams from statutory and private patients. The target audience includes local residents, children, and patients from Belgium and the Netherlands. The website reflects a consistent branding strategy and trust signals such as Jameda ratings. The partnership ecosystem includes medical certification bodies and local healthcare networks. Growth indicators are not explicitly stated but the presence of online appointment requests suggests digital engagement.

Security posture

The website demonstrates a moderate to good security posture with HTTPS enforced and a cookie consent mechanism implemented via Klaro. No vulnerable libraries or exposed sensitive data were detected in the HTML content. However, the absence of published security policies, incident response contacts, and security headers like Content-Security-Policy or X-Frame-Options indicates gaps in security maturity. There is no evidence of vulnerability disclosure or security.txt files. The site does not appear to use analytics or tracking scripts, reducing privacy risks. Overall, the security posture is adequate for a healthcare provider's informational website but could be enhanced with formal policies and technical headers.

Recommendations

  1. Publish a dedicated security policy page outlining security practices and data protection measures.
  2. Provide clear incident response contact information such as security@ or abuse@ email addresses.
  3. Implement and configure HTTP security headers including Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security.
  4. Enhance website accessibility to meet WCAG standards for improved user inclusivity.
  5. Consider adding terms of service to clarify user and patient engagement rules and liabilities.

Technical notes

Notes

The website is built on the Contao CMS platform, leveraging jQuery, Leaflet.js for maps, LightSlider for image sliders, and Klaro for cookie consent management. The site uses modern HTML5 and CSS3 standards with responsive design techniques for mobile optimization. Performance is moderate, with some large images in sliders but generally acceptable load times. The site lacks advanced frameworks or platforms but maintains a clean and functional technical infrastructure. There is no evidence of third-party analytics or advertising scripts, indicating low technical complexity and reduced privacy concerns. Opportunities exist to modernize the tech stack and improve accessibility and security headers for enhanced robustness.
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.
