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

The Deutscher Berufsverband der Hals-Nasen-Ohrenärzte e.V. operates as a professional association for ENT (ear, nose, throat) specialists in Germany. The website serves as a comprehensive portal offering information about the association, professional development events, a marketplace for medical equipment and job postings, and patient education resources. It targets medical professionals and practice staff, positioning itself as a leading entity in the German healthcare sector for ENT specialists. Technically, the website is built on TYPO3 CMS, leveraging modern web technologies including Matomo for analytics and responsive design frameworks. The infrastructure is hosted on servers indicated by the agenturserver nameservers, with good mobile optimization and accessibility features. The site implements a cookie consent mechanism compliant with GDPR, and uses HTTPS with a solid SSL configuration. From a security perspective, the site demonstrates good practices such as encrypted connections, cookie consent, and no visible vulnerabilities or exposed sensitive data. However, it lacks explicit security policy documentation and incident response contacts, which are recommended for enhanced trust and compliance. The WHOIS data aligns well with the website's claims, supporting legitimacy. Overall, the website is professional, trustworthy, and well-maintained, with minor areas for improvement in security transparency and policy disclosures.

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

7 findings rated critical or high. Fix these first.

  1. 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

  2. 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';…

  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 · 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 association holds a strong market position as the primary professional body for ENT doctors in Germany, offering a mix of membership services, educational events, and a marketplace that supports the professional needs of its members. Its revenue model likely includes membership fees, event registrations, and advertising or listing fees on its marketplace. The target audience is clearly defined as medical professionals and practice personnel, with patient education as a secondary focus. The organization maintains partnerships with related medical societies and professional groups, enhancing its ecosystem and influence. Growth indicators include active event scheduling and digital engagement through social media and patient portals.

Security posture

The website exhibits a mature security posture with HTTPS enforced and a cookie consent mechanism that respects user privacy. The use of Matomo analytics suggests a preference for privacy-friendly tracking. No critical vulnerabilities or exposed sensitive data were detected. However, the absence of a published security policy, incident response contacts, and security.txt file indicates room for improvement in transparency and preparedness. Security headers were not explicitly detected in the provided data, which could be enhanced to mitigate common web threats. Overall, the site is secure but could benefit from formalizing and publishing its security governance documents.

Recommendations

  1. Publish a dedicated security policy page outlining security practices and commitments.
  2. Add incident response contact information or abuse@ email addresses for reporting security issues.
  3. Implement and publish a security.txt file to facilitate vulnerability disclosures.
  4. Enhance HTTP security headers such as Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security.
  5. Regularly review and update third-party scripts and libraries to mitigate potential vulnerabilities.

Technical notes

Notes

The website is built on TYPO3 CMS, a robust and widely used content management system suitable for professional organizations. It uses Matomo for analytics, which is privacy-conscious compared to alternatives. The site is mobile-optimized and accessible, with good SEO practices including meta tags and structured navigation. Hosting appears stable with agenturserver nameservers. Performance is moderate, likely adequate for the target audience. The use of modern JavaScript libraries like autoComplete.js enhances user experience. There is no indication of technical debt or outdated technologies, but adding security headers and formalizing security documentation would improve the technical maturity.
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.
