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

Tennisverband Mittelrhein e.V. is a regional tennis association in Germany, serving tennis players and clubs in the Mittelrhein region. The website provides basic information about the association but lacks comprehensive business and legal disclosures such as privacy policy and terms of service. The technical infrastructure includes modern JavaScript usage and cookie consent management via Cookiebot, with Cloudflare DNS providing hosting and security benefits. Security posture is moderate with some best practices like consent management but lacks visible security headers and detailed policies. Overall, the website is functional but could improve in transparency, contact availability, and SEO optimization.

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

2 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 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. Network security

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

    • High

      High-Risk Service Exposed: FTP

      Port 21 (FTP) is publicly accessible - FTP - Often unencrypted file transfer

      What to do: Consider restricting access to FTP or implementing strong authentication

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 association operates as a non-profit sports entity focused on tennis in a specific German region. Its business model centers on member services and event organization. The website targets tennis enthusiasts and clubs, but lacks detailed business information or certifications. The absence of contact details and legal policies may limit trust and engagement. The use of Cloudflare and Cookiebot indicates some investment in infrastructure and compliance, but further enhancements are needed to improve credibility and user trust.

Security posture

The website employs HTTPS and Cloudflare DNS, which provide baseline security. Cookie consent is managed with explicit denial of ad and analytics storage by default, indicating privacy awareness. However, no security headers were detected, and no incident response or security policies are published. The lack of visible contact channels for security incidents and absence of vulnerability disclosure mechanisms suggest limited security maturity. Recommendations include adding security headers, publishing policies, and providing clear incident response contacts.

Recommendations

  1. Publish a comprehensive privacy policy and terms of service to improve legal compliance and user trust.
  2. Add clear contact information including emails and phone numbers for general and security inquiries.
  3. Implement and configure security headers such as Content-Security-Policy and X-Frame-Options.
  4. Enhance SEO by adjusting meta robots tag and improving meta descriptions.
  5. Establish a vulnerability disclosure policy and incident response contact to strengthen security posture.

Technical notes

Notes

The website uses modern JavaScript modules alongside legacy scripts for compatibility, indicating a moderate level of technical maturity. Hosting is via Cloudflare DNS, which enhances performance and security. Cookiebot is integrated for cookie consent management. However, no CMS or frameworks were explicitly detected. The site has basic mobile optimization and accessibility but limited SEO due to meta robots settings. Performance is moderate, with room for improvement in loading speed and technical SEO. Technical debt appears low but transparency and security configurations need enhancement.
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.
