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

The Global Professional Tennis Coach Association (GPTCA) is a Switzerland-based organization founded in 2012, dedicated to educating and supporting professional tennis coaches aiming to work at ATP Tour and women's pro tennis levels. The website serves as a global hub offering membership, educational courses, events, and resources tailored to tennis coaching professionals. It maintains partnerships with recognized entities such as ATP, ITIA, and Golden Set Analytics, enhancing its credibility and market position. Technically, the website employs a modern tech stack including Google Analytics, Google Tag Manager, Alpine.js, Swiper.js, and AOS for animations, hosted likely on home.pl infrastructure. The site is mobile-optimized with good SEO practices and a consistent branding approach. However, some accessibility features are basic, and performance is moderate. From a security perspective, the site uses HTTPS and has domain transfer protections but lacks DNSSEC and visible security headers. There are no privacy or cookie policies published, representing compliance gaps. No incident response or vulnerability disclosure information is provided. The domain WHOIS data is consistent and legitimate, supporting trustworthiness. Overall, the website is professional and trustworthy but would benefit from enhanced privacy compliance, security headers, and incident response transparency to improve its security posture and regulatory adherence.

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

9 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 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';…

  2. GDPR outside view

    These are the privacy signals visitors and data protection authorities look for under GDPR.

    • High

      No Privacy Policy found

      GDPR requires a clear and accessible privacy policy

      What to do: Add a comprehensive privacy policy page and link to it prominently

    • 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

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

GPTCA operates in the niche market of professional tennis coaching education and membership services. Its competitive advantage lies in its global recognition, partnerships with ATP and other tennis bodies, and a comprehensive coaching pathway. Revenue likely derives from membership fees and course enrollments. The target customers are professional and aspiring tennis coaches worldwide. Growth indicators include scheduled upcoming courses and new educational initiatives like the Tennis Parent Education platform. The partnership ecosystem strengthens its market presence and credibility. Operationally, the organization maintains a clear focus on tennis coaching education and community building.

Security posture

The current security maturity level is moderate. HTTPS is enforced, and domain transfer protection is enabled, but DNSSEC is not active. The absence of security headers such as Content-Security-Policy and Strict-Transport-Security reduces defense-in-depth. No privacy or cookie policies are published, indicating GDPR compliance gaps. Incident response readiness is unclear due to lack of contact channels for security issues. The use of third-party analytics and scripts introduces potential vulnerabilities if not regularly audited. Overall, the security culture appears basic with room for improvement in transparency and technical controls.

Recommendations

  1. Publish a comprehensive privacy policy and cookie policy to address GDPR and privacy compliance.
  2. Enable DNSSEC on the domain to enhance DNS security.
  3. Implement security headers including Content-Security-Policy, X-Content-Type-Options, and Strict-Transport-Security.
  4. Provide clear incident response contact information such as security@ or abuse@ email addresses.
  5. Regularly review and update third-party scripts and analytics tools to mitigate vulnerabilities.

Technical notes

Notes

The website uses a modern front-end technology stack with libraries like Alpine.js, Swiper.js, and AOS for UI/UX enhancements. Google Fonts and CDN-hosted CSS/JS improve performance and maintainability. The CMS appears to be DobryCMS, a less common but specialized content management system. Hosting is inferred to be via home.pl based on nameservers. The site is mobile responsive and SEO optimized with proper meta tags and Open Graph data. Performance is moderate, with potential for improvement by optimizing script loading and caching. Accessibility is basic, suggesting opportunities to enhance ARIA roles and keyboard navigation support.
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.
