Swiss Tennis is the official national tennis federation of Switzerland, serving as the central hub and competence center for tennis activities in the country. The organization provides comprehensive services including tournament management, player rankings, coach education, and support for clubs and regional associations. The website reflects a mature digital presence with extensive content tailored to tennis players, coaches, and enthusiasts. It maintains a strong market position as the authoritative body for tennis in Switzerland, supported by partnerships with related platforms such as myTennis and myKidsTennis. Technically, the website employs modern web technologies including Google Tag Manager, Google Analytics, CookieYes for consent management, and Google Maps API. The CMS used is MoveCMS by MovePeople.ch. The site is mobile-optimized, well-structured, and performs moderately well. SEO and accessibility are adequately addressed, though some improvements could be made in accessibility features. From a security perspective, the site enforces HTTPS and uses secure login mechanisms via Microsoft B2C OAuth. A comprehensive cookie consent mechanism is implemented, supporting GDPR compliance. However, explicit security headers like CSP and X-Frame-Options are not clearly detected and could be enhanced. No critical vulnerabilities or exposed sensitive data were found. Overall, Swiss Tennis presents a trustworthy, professional, and user-friendly website that aligns well with its role as a national sports federation. Strategic recommendations include enhancing security headers, publishing a security policy, and improving accessibility compliance to further strengthen its security posture and user trust.

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

6 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 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
    • High

      Weak SSL Key Length

      SSL certificate uses 384-bit key, which is considered weak

      What to do: Use at least 2048-bit RSA or 256-bit ECC key

      • CWE-326
      • OWASP A04:2025
      • Mozilla TLS: Mozilla Server Side TLS 6.0 intermediate: rsa_key_size 2048

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

Swiss Tennis operates as a non-profit sports federation focused on tennis in Switzerland. It holds a dominant market position as the national governing body, offering services such as tournament organization, player ranking systems, coach and official education, and community support. Revenue streams likely include membership fees, event sponsorships, partnerships, and educational programs. The target audience encompasses tennis players of all levels, coaches, clubs, regional associations, and tennis fans. The organization maintains a robust partnership ecosystem with platforms like myTennis and myKidsTennis, as well as corporate partners like Swica. Growth indicators include digital platform expansions and new competition formats like Match Up. The website content and structure reflect a mature operation with consistent branding and comprehensive service offerings.

Security posture

The website demonstrates a good security maturity level with enforced HTTPS, secure authentication via Microsoft B2C OAuth, and a detailed cookie consent mechanism supporting GDPR compliance. No exposed sensitive data or vulnerable libraries were detected in the HTML content. However, the absence of explicit security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options suggests room for improvement. There is no publicly visible security policy or incident response contact information, which could enhance transparency and readiness. The use of third-party scripts like Google Analytics and Facebook Pixel is managed with user consent. Overall, the security posture is solid but could be strengthened by implementing recommended headers and publishing security documentation.

Recommendations

  1. Implement and enforce security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to mitigate common web vulnerabilities.
  2. Publish a clear security policy and provide incident response contact channels to improve transparency and preparedness.
  3. Enhance accessibility features to meet higher compliance standards and improve user experience for all visitors.
  4. Regularly audit third-party scripts and dependencies to ensure no vulnerabilities are introduced.
  5. Consider adding a vulnerability disclosure policy or security.txt file to encourage responsible reporting.

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.
