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. 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.

    • Critical

      No email authentication configured

      Domain is vulnerable to email spoofing

      What to do: Implement SPF, DKIM, and DMARC immediately

  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

      Prevents clickjacking attacks

      What to do: Add "X-Frame-Options: DENY" or "X-Frame-Options: SAMEORIGIN"

    • 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. GDPR outside view

    These are the privacy signals visitors and data protection authorities look for under GDPR.

    • 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

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 portal operates within the education and non-profit sectors, specifically targeting sports education in Hamburg. Its business model revolves around collaboration with multiple sports federations and organizations, providing a unified platform for seminar listings and registrations. The presence of multiple partner domains and logos indicates a strong partnership ecosystem. The domain age and WHOIS data align well with the business history, enhancing credibility. The platform likely generates value through service facilitation rather than direct revenue, focusing on community and volunteer engagement. Growth potential exists through expanding partner networks and digital offerings. The absence of direct contact information on the homepage suggests a focus on online self-service and possibly centralized contact via parent organization channels.

Security posture

The website enforces HTTPS and includes a cookie consent mechanism, indicating awareness of privacy and security best practices. However, the absence of DNSSEC and security headers such as Content-Security-Policy or X-Frame-Options represents areas for improvement. No forms or input fields were detected on the homepage, reducing attack surface. There is no visible incident response or vulnerability disclosure information, which could be enhanced to improve transparency and readiness. Overall, the security posture is moderate with no critical issues but room for strengthening defenses and compliance documentation.

Recommendations

  1. Enable DNSSEC on the domain to enhance DNS security and prevent spoofing.
  2. Implement standard security headers (CSP, X-Frame-Options, X-Content-Type-Options) to mitigate common web attacks.
  3. Publish a dedicated security policy and incident response contact information to improve transparency and trust.
  4. Add a vulnerability disclosure policy or security.txt file to encourage responsible reporting of security issues.
  5. Consider adding clear contact information on the website for user support and compliance purposes.

Technical notes

Notes

The website uses a modern, responsive design with Bootstrap and jQuery, ensuring compatibility across devices and good accessibility. The use of Flexslider indicates some interactive UI elements. Hosting by Host Europe Group is consistent with the domain registration. Performance is moderate with no obvious issues but could benefit from optimization. No CMS was detected, suggesting a custom or static site approach. SEO is supported by proper meta tags and structured navigation. No analytics or tracking scripts were found, indicating minimal user tracking and good privacy posture. The technical stack is solid but could be enhanced with additional security and performance optimizations.
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.
