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

RSG Langenhagen 82 e.V. is a well-established non-profit sports club specializing in wheelchair sports in the Hannover region of Germany. The organization offers a variety of sports activities including badminton, wheelchair basketball, swimming, and self-defense workshops targeted primarily at children, youth, and individuals with physical disabilities. The club holds a strong regional position as a founding member of the German Wheelchair Sports Association and maintains partnerships with local foundations and organizations. The website content is comprehensive and well-structured, providing detailed information about events, workshops, and club news in German. Technically, the site is built on the IONOS MyWebsite CMS platform, uses modern web technologies, and is hosted by IONOS. It is mobile-optimized and provides a good user experience, though accessibility features could be improved. Security posture is adequate with HTTPS enabled but lacks advanced security headers and published security policies. Privacy compliance is partial, with a privacy policy present but no cookie consent mechanism or GDPR explicit indicators. Overall, the site is trustworthy and professional but could benefit from enhanced security and privacy features.

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

  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 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

    • 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

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

The club operates in the non-profit sports sector, focusing on wheelchair sports and inclusive activities. Its business model revolves around community engagement, workshops, and sports training rather than commercial revenue. The organization leverages partnerships with local foundations and institutions to support its activities. The target audience includes people with disabilities, families, and sports enthusiasts in the Hannover region. The website reflects a strong community orientation with frequent updates on events and news. The club's longevity and founding member status provide competitive advantages in the regional sports market. The partnership ecosystem includes local airports, foundations, and sports funds, enhancing credibility and resource access.

Security posture

The website demonstrates a basic security maturity level with HTTPS enforced, ensuring encrypted communications. However, the absence of key security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options indicates room for improvement in mitigating common web vulnerabilities. No incident response or security policy is published, and no dedicated security contact channels are provided. There is no evidence of vulnerability disclosure mechanisms or security.txt files. The lack of cookie consent mechanisms may expose the organization to GDPR compliance risks. Overall, while no critical vulnerabilities are apparent, the security posture would benefit from adopting best practices and formalizing security policies.

Recommendations

  1. Implement comprehensive security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to enhance protection against common web attacks.
  2. Add a cookie consent banner and mechanism to comply with GDPR and improve user privacy transparency.
  3. Publish a clear security policy and incident response contact information to improve trust and preparedness.
  4. Consider establishing a vulnerability disclosure program or security.txt file to encourage responsible reporting of security issues.
  5. Enhance website accessibility features to improve usability for all users, including those with disabilities.

Technical notes

Notes

The website is built using the IONOS MyWebsite CMS platform, leveraging standard web technologies such as HTML5, CSS3, JavaScript, and jQuery. It uses CDN services from website-start.de and is hosted by IONOS, ensuring reliable infrastructure. The site is mobile-optimized with responsive design and includes SEO meta tags and Open Graph metadata for social sharing. Performance is moderate, with no major issues detected in the HTML content. However, the site lacks advanced analytics or tracking tools, which may limit marketing insights. The technical stack is stable but could be modernized by adopting newer JavaScript frameworks and improving accessibility 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.
