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

Prellball.de is a German-language informational website dedicated to the sport of Prellball, providing comprehensive coverage of leagues such as Bundesliga and Regionalliga, championships, training resources, and news updates. The site targets Prellball players, clubs, and enthusiasts primarily within Germany, serving as a niche community and information hub. The business model is informational with community engagement through newsletters and social media. Technically, the website is built using modern web technologies including React and Gatsby, ensuring fast performance and good mobile optimization. Hosting appears to be managed by 1&1 IONOS, inferred from the nameservers. The site uses minimal tracking via Simple Analytics, respecting user privacy. SEO and accessibility are adequately addressed, though some improvements could be made. From a security perspective, the site enforces HTTPS and avoids exposing sensitive data. However, security headers are not evident, and no formal security or incident response policies are published. Privacy compliance is basic but present with a privacy policy; cookie consent mechanisms are missing. No critical vulnerabilities or suspicious WHOIS patterns were detected, though WHOIS data is minimal. Overall, Prellball.de is a well-maintained, niche sports information site with good technical implementation and moderate security posture. Strategic improvements in security headers, cookie consent, and formal policies would enhance 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.

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

7 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

    • High

      No Cookie Consent Banner found

      GDPR requires explicit consent for non-essential cookies

      What to do: Implement a cookie consent banner that appears on first visit

  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 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. Email security

    SPF, DKIM and DMARC stop others sending email that looks like it comes from your domain, a common route to phishing and invoice fraud.

    • High

      No SPF record found

      SPF helps prevent email spoofing

      What to do: Add SPF record: "v=spf1 include:_spf.yourmailprovider.com ~all"

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

Prellball.de occupies a niche market as the primary German-language portal for Prellball sport information. It leverages partnerships with official bodies like the German Tennis Federation (DTB) and related Prellball projects. The site’s competitive advantage lies in its focused content, community engagement via newsletters, and social media presence. Revenue streams are not explicit but likely limited to sponsorships or federation support. The target audience includes sports clubs, players, and fans interested in Prellball. Growth indicators include active content updates and event calendars. The partnership ecosystem is modest but relevant to the sport’s community.

Security posture

The website demonstrates a moderate security maturity level with HTTPS enforced and no visible sensitive data leaks. However, the absence of security headers such as Content Security Policy (CSP), HSTS, and X-Frame-Options reduces its defense-in-depth. No vulnerability disclosures or incident response information is provided, indicating limited formal security governance. GDPR compliance is partially addressed via a privacy policy but lacks cookie consent mechanisms. The use of minimal tracking analytics aligns with privacy best practices. Overall, the security posture is adequate for a small informational site but could benefit from enhanced policies and technical controls.

Recommendations

  1. Implement security headers including CSP, HSTS, and X-Frame-Options to strengthen browser security.
  2. Add a cookie consent banner to comply fully with GDPR and inform users about tracking.
  3. Publish terms of service and a formal security policy to improve transparency and legal compliance.
  4. Consider establishing an incident response contact channel (e.g., security@ or abuse@ email).
  5. Regularly review and update privacy and security documentation to maintain compliance and trust.

Technical notes

Notes

The site is built on a modern React and Gatsby framework, enabling fast loading times and good mobile responsiveness. The use of server-side rendering and static site generation contributes to performance and SEO benefits. Hosting via 1&1 IONOS provides reliable infrastructure. The absence of a traditional CMS suggests custom development, which may reduce attack surface but requires ongoing maintenance. The site uses minimal external scripts, primarily for analytics and social media integration, reducing complexity. Opportunities exist to improve accessibility and implement advanced SEO techniques. No technical debt or major risks were identified in the current implementation.
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.
