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. 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

    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 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
  • 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.

Business context

Business profile

GKMB GmbH operates as a niche web agency with a focus on TYPO3 CMS solutions tailored to the golf industry and other sectors such as communication, industry, and service providers. Their flagship product, ClubWebMan®, is a market leader in the German-speaking golf market, providing specialized content management and event management tools. The company also offers ContentFactory for broader industry applications, compliance solutions, media production, and SEO services. Their business model revolves around providing customizable, scalable web and marketing solutions with a strong emphasis on compliance and customer support. The presence of customer testimonials and awards indicates a positive reputation and customer satisfaction. GKMB maintains a partner ecosystem including a dedicated support domain and social media engagement, supporting growth and client retention.

Security posture

GKMB GmbH demonstrates a solid security posture with HTTPS enforced site-wide and a comprehensive cookie consent mechanism that allows users to control tracking and data collection. The use of self-hosted Matomo analytics reduces reliance on third-party trackers, enhancing privacy compliance. However, the absence of explicit security headers such as Content-Security-Policy or X-Frame-Options is a gap that could be addressed to mitigate risks like clickjacking or cross-site scripting. No incident response or security policy information is publicly available, which could limit transparency and preparedness in case of security events. No vulnerabilities or exposed sensitive data were found in the analyzed content. Overall, the security maturity is good but could be improved with additional security best practices and public disclosures.

Recommendations

  1. Implement and configure security headers including Content-Security-Policy, X-Frame-Options, and X-XSS-Protection to enhance protection against common web attacks.
  2. Publish a clear security policy and incident response contact information to improve transparency and readiness.
  3. Add a security.txt file to facilitate responsible vulnerability disclosure and improve trust with security researchers.
  4. Regularly audit and update third-party libraries and scripts to prevent vulnerabilities from outdated components.
  5. Enhance monitoring and logging capabilities to detect and respond to security incidents promptly.

Technical notes

Notes

The website is built on TYPO3 CMS, a robust and widely used open-source content management system, indicating a mature and scalable infrastructure. The front-end uses modern JavaScript libraries such as jQuery 3.7.1, Swiper for sliders, Plyr for media playback, and Fancybox for modals, providing a rich interactive user experience. The site loads CSS and fonts efficiently, including preloading key font assets, which supports good performance. The presence of responsive design and accessibility features suggests attention to user experience across devices. The use of a self-hosted Matomo analytics platform reflects a commitment to privacy. However, the lack of visible security headers and limited WHOIS data are areas for potential technical improvement. Overall, the technical implementation is solid with good opportunities for further hardening and modernization.
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.
