The website tennis.de serves as the official platform for the Deutscher Tennis Bund (DTB), focusing on providing comprehensive information about the Regionalliga Nord-Ost and related tennis leagues in Germany. It offers league results, official documents, contact details for league officials, and integrates with the nuLiga platform for result entry. The site targets tennis players, clubs, officials, and fans primarily in northern and eastern Germany. The business model revolves around sports federation services and information dissemination.
Technically, the site is built on Adobe Experience Manager (AEM) with modern JavaScript frameworks including ZK Framework and Litepicker. It is hosted on Adobe's cloud infrastructure, ensuring reliable performance and scalability. The site is mobile-optimized, accessible, and SEO-friendly, with a moderate performance profile. Cookie consent is managed via Cookiebot, and Google Tag Manager is used for analytics and marketing.
From a security perspective, the site enforces HTTPS and uses consent management for cookies, but lacks explicit security headers and a published security policy or incident response contacts. No vulnerabilities or suspicious content were detected. The domain WHOIS data indicates professional management consistent with a reputable organization.
Overall, the website is a trustworthy, well-maintained official sports federation site with good content quality and technical implementation. Strategic improvements could include enhanced security headers and publishing a security policy to further strengthen trust and compliance.

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.

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.

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.

Business context
Business profile
The Deutscher Tennis Bund operates as the national governing body for tennis in Germany, with tennis.de as its official digital presence. The site supports league management and communication for regional leagues such as Regionalliga Nord-Ost, Nordliga, and Ostliga, as well as related sports like Padel and Beach Tennis. The platform provides official documents, schedules, and contact information, facilitating efficient league operations and fan engagement. Partnerships with brands like Dunlop indicate strong industry relationships. The business model is service-oriented, focusing on sports administration and community support. The site’s comprehensive content and authoritative positioning reinforce DTB's market leadership in German tennis.
Security posture
The website demonstrates a solid security posture with mandatory HTTPS encryption and integration of cookie consent mechanisms compliant with GDPR. Use of Google Tag Manager is controlled via consent management, reducing privacy risks. However, the absence of explicit security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options represents an area for improvement. No incident response or vulnerability disclosure information is published, which could hinder rapid response to security events. No exposed sensitive data or vulnerable libraries were detected. Overall, the site is secure but could benefit from enhanced security best practices and transparency.
Recommendations
Implement and configure security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to mitigate common web attacks.
Publish a clear security policy and incident response contact information to improve transparency and readiness.
Add a vulnerability disclosure policy or security.txt file to facilitate responsible reporting of security issues.
Regularly audit third-party scripts and libraries to ensure no vulnerabilities are introduced.
Enhance monitoring and logging to detect and respond to potential security incidents promptly.

Notes
The website leverages Adobe Experience Manager (AEM) as its CMS, indicating a robust enterprise-grade content management infrastructure. The use of ZK Framework and Litepicker JavaScript libraries supports dynamic UI components such as date pickers and widgets. Hosting on Adobe's cloud platform ensures scalability and reliability. The site includes Google Tag Manager for analytics and marketing, integrated with Cookiebot for consent management. Performance is moderate, with good mobile optimization and accessibility features. The site structure and metadata support SEO best practices. Opportunities exist to optimize loading speed and implement additional security headers for improved resilience.
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.
