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

The Tennisverband Mecklenburg-Vorpommern e.V. is a regional tennis association dedicated to promoting tennis activities, organizing tournaments, and supporting youth development within Mecklenburg-Vorpommern, Germany. The website serves as an information hub for players, clubs, and tennis enthusiasts, providing news, event details, and organizational resources. It positions itself as the official governing body for tennis in the region, operating as a non-profit entity focused on community engagement and sport development. Technically, the website is built on WordPress 6.8.3 using the GeneratePress theme and Visual Composer Website Builder, supplemented by plugins such as Contact Form 7 and Owl Carousel for enhanced user experience. The site is mobile-optimized with a moderate performance profile and good SEO practices, though accessibility features are basic. The infrastructure reflects a standard modern CMS setup suitable for small to medium-sized organizations. From a security perspective, the site enforces HTTPS with a good SSL configuration but lacks visible HTTP security headers such as CSP or HSTS in the HTML content. No exposed sensitive data or vulnerable libraries were detected. Privacy compliance is supported by a comprehensive GDPR-aligned privacy policy, though no cookie consent mechanism is present. Contact information is primarily via forms, with no explicit emails or phone numbers found in the content. Overall, the website is trustworthy and professional, with a strong focus on tennis-related content and community engagement. Security posture is adequate but could be improved with additional headers and consent mechanisms. The domain registration data is consistent and legitimate, supporting the site's credibility. Strategic improvements in security and privacy compliance would enhance the site's resilience 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.

Priority findings

6 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

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

The Tennisverband Mecklenburg-Vorpommern e.V. operates as a regional sports association within the tennis sector, targeting tennis players, clubs, and youth in Mecklenburg-Vorpommern. Its business model is non-profit, focusing on organizing events, talent development, and providing resources to member clubs. The association leverages partnerships with tennis leagues, insurance providers, and equipment manufacturers, as evidenced by linked domains. The website content and structure indicate a stable market position as the official regional tennis authority. Growth indicators include active youth programs and regular tournaments. The partnership ecosystem includes recognized tennis platforms and sponsors, enhancing its operational reach and credibility.

Security posture

The website demonstrates a moderate security maturity level with HTTPS enforced and no visible sensitive data leaks. However, the absence of key HTTP security headers such as Content Security Policy (CSP), HTTP Strict Transport Security (HSTS), and X-Frame-Options reduces its defense-in-depth posture. The use of reputable plugins and a maintained WordPress core suggests reasonable patch management. No explicit incident response or vulnerability disclosure policies are found, indicating potential gaps in security governance. GDPR compliance is supported by a detailed privacy policy, but the lack of a cookie consent mechanism may expose the organization to compliance risks. Overall, the security posture is functional but would benefit from enhanced header implementation, formal incident response channels, and improved privacy controls.

Recommendations

  1. Implement HTTP security headers including CSP, HSTS, X-Frame-Options, and X-XSS-Protection to strengthen browser security.
  2. Deploy a cookie consent banner/mechanism to ensure full GDPR compliance and user transparency.
  3. Establish and publish a vulnerability disclosure policy or security.txt file to improve security communication.
  4. Enhance accessibility features to improve usability for all users, including those with disabilities.
  5. Regularly audit and update all plugins and WordPress core to mitigate vulnerabilities and maintain security.

Technical notes

Notes

The website is built on a modern WordPress CMS platform using the GeneratePress theme and Visual Composer for layout management. It incorporates jQuery and Owl Carousel for interactive elements and Contact Form 7 for user input. The site is mobile responsive with good SEO meta tags and structured navigation. Performance is moderate, with potential improvements in caching and asset optimization. No major technical debt is evident, but the absence of security headers and cookie consent mechanisms indicates areas for modernization. Hosting details are not explicit, but multiple authoritative DNS servers suggest stable infrastructure. Overall, the technical implementation supports the business needs effectively but could be enhanced for security and compliance.
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.
