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. 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. 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

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 Tennisverband Rheinland operates as a non-profit regional sports association focused on tennis in Rheinland-Pfalz, Germany. Its market position is that of a regional governing body, providing essential services such as tournament organization, league management, trainer education, and sport development. The business model centers on community service and sport promotion rather than commercial revenue generation. The target audience includes tennis players, clubs, trainers, and tennis enthusiasts within the region. The association leverages partnerships with national tennis bodies and digital platforms for player registration and hall booking, indicating a collaborative ecosystem. Growth indicators include active event scheduling and training programs. The website content and structure reflect a stable and established organization with consistent branding and clear communication.

Security posture

The website demonstrates a moderate security maturity level. HTTPS is enforced, and login forms use secure POST methods. However, the absence of explicit security headers such as Content Security Policy (CSP), HTTP Strict Transport Security (HSTS), and X-Frame-Options reduces the overall security posture. No security or incident response policies are published, and no dedicated security contact channels were found. The use of third-party scripts like Google Tag Manager and eyeAble introduces potential risk vectors that require regular auditing. Privacy compliance is basic, with a privacy policy present but lacking cookie consent mechanisms. No vulnerabilities or exposed sensitive data were detected in the HTML content. Overall, the site is secure for general use but would benefit from enhanced security controls and transparency to meet higher compliance standards such as GDPR and NIS2.

Recommendations

  1. Implement comprehensive security headers including CSP, HSTS, and X-Frame-Options to mitigate common web attacks.
  2. Add a clear cookie consent banner to comply with GDPR and enhance user privacy transparency.
  3. Publish a security policy and incident response plan on the website, including dedicated security contact emails.
  4. Regularly audit and update third-party scripts to minimize vulnerabilities and ensure compliance.
  5. Enhance privacy compliance by detailing data retention policies and user rights in the privacy policy.

Technical notes

Notes

The website is built on TYPO3 CMS, a mature and widely used content management system, combined with Bootstrap for responsive design. The technical infrastructure includes integration with Google Tag Manager for analytics and eyeAble for accessibility enhancements. Hosting is provided by agenturserver, indicated by the nameservers. The site demonstrates good mobile optimization and accessibility features, with proper meta tags and SEO-friendly structure. Performance is moderate, with compressed CSS and JS assets. No critical technical debt or outdated technologies were detected. Opportunities exist to improve security headers and cookie consent mechanisms to align with modern web standards and compliance requirements.
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.
