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

MTV v. 1848 Hildesheim e.V. is a well-established local sports club in Germany, offering a wide range of sports and health-related activities including courses, training, rehabilitation sports, and community events. The club targets a broad audience including families, children, seniors, and sports enthusiasts within the Hildesheim region. Their market position as the oldest sports club in Hildesheim supports a strong community presence and trust. Technically, the website is built with standard web technologies including HTML5, CSS, and JavaScript, enhanced by Matomo analytics for user tracking and Sliderm.js for interactive slideshows. Hosting is provided by rzone.de, and the site demonstrates good mobile optimization and SEO practices, though accessibility features are basic. From a security perspective, the site uses HTTPS and avoids exposing sensitive data. However, it lacks visible security headers, a cookie consent mechanism, and formal security or incident response policies. The use of Matomo suggests some privacy awareness, but GDPR compliance could be improved by adding explicit cookie consent and privacy notices. Overall, the website is professional, trustworthy, and content-rich, serving its community effectively. Strategic improvements in privacy compliance and security posture would enhance user trust 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

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

      What to do: Add "Strict-Transport-Security: max-age=31536000; includeSubDomains; preload"

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

MTV v. 1848 Hildesheim e.V. operates as a non-profit sports organization with a strong local presence and historical significance. Its business model focuses on community engagement through sports and health programs, generating revenue primarily via memberships, course fees, and sponsorships. The club's competitive advantage lies in its broad service offering and certifications that enhance credibility. Partnerships with regional organizations and certifications like the Familiensiegel and Rehasport group reinforce its market position. Growth indicators include new course offerings and active event scheduling. The club maintains a clear partnership ecosystem with local banks and sports federations, supporting its operational and promotional activities.

Security posture

The website demonstrates a moderate security maturity level with HTTPS enabled and no visible sensitive data leaks. However, the absence of security headers such as Content-Security-Policy and X-Frame-Options reduces protection against common web attacks. The lack of a published security policy or incident response contact limits transparency and preparedness. GDPR compliance is partially addressed via a privacy policy, but cookie consent mechanisms are missing. No known vulnerabilities or malicious content were detected. Overall, the security posture is adequate for a community sports site but could benefit from enhancements to align with best practices and regulatory requirements.

Recommendations

  1. Implement a cookie consent banner to comply with GDPR and enhance user privacy transparency.
  2. Add security headers like Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security to improve protection against web attacks.
  3. Publish a clear security policy and incident response contact information to improve transparency and readiness.
  4. Conduct a security audit of all third-party scripts and libraries to ensure no vulnerabilities are present.
  5. Enhance accessibility features to improve usability for all users, including those with disabilities.

Technical notes

Notes

The website uses a straightforward technology stack with HTML5, CSS, and JavaScript, supplemented by Matomo for analytics and Sliderm.js for interactive elements. Hosting is managed via rzone.de, indicating a stable infrastructure. Performance is moderate with good mobile responsiveness and SEO optimization. However, the site lacks modern web frameworks or CMS indications, which may limit scalability and ease of content management. There is an opportunity to modernize the tech stack and improve accessibility and security features to reduce technical debt and enhance user experience.
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.
