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. 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';…

  2. 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

    • 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

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 company GRITH AG operates VereinOnline as a specialized software solution for clubs and associations, offering a SaaS model with multiple integrated services. The market positioning is solid with a long domain history and industry recognition. Revenue streams likely include subscriptions or licenses for software use, app services, and possibly custom app development. The target customers are clubs, associations, and similar groups needing digital management tools. The partnership ecosystem includes the parent company GRITH AG and external widget providers like accessGo. The business shows signs of stability and growth potential with a medium-sized operation and a clear focus on the German market.

Security posture

The security maturity level is moderate. The domain is protected against unauthorized transfers (clientTransferProhibited), but DNSSEC is not enabled, which is a recommended best practice. No security headers were detected in the provided data, indicating room for improvement in HTTP security configurations. The website does not expose sensitive data or emails directly, and role-based access control is described in the product features. There is no visible incident response or vulnerability disclosure information, which could be improved to enhance security culture and transparency. GDPR compliance is addressed with a dedicated privacy policy. Overall, the site is secure enough for its business purpose but could benefit from enhanced technical security controls and formalized security policies.

Recommendations

  1. Enable DNSSEC on the domain to improve DNS security and prevent spoofing.
  2. Implement standard security HTTP headers such as Content-Security-Policy, Strict-Transport-Security, X-Frame-Options, and X-Content-Type-Options.
  3. Add a cookie consent banner or mechanism to comply fully with EU cookie regulations.
  4. Publish a vulnerability disclosure policy or security.txt file to facilitate responsible reporting.
  5. Provide direct contact information such as a company email or phone number on the website to improve trust and accessibility.

Technical notes

Notes

The website uses a modern and stable technology stack including Bootstrap for responsive design, jQuery for DOM manipulation, Font Awesome for icons, and additional libraries like PrettyPhoto and WOW.js for UI effects. The site is custom-built without a standard CMS, which can reduce common CMS vulnerabilities but requires careful maintenance. Hosting is through IONOS SE, a reputable provider. Performance is moderate with no explicit speed metrics but no obvious blocking scripts or heavy ads. Mobile optimization is good, supported by responsive layouts and dedicated apps for Android and iOS. Accessibility features are implemented, including skip links and keyboard focus styles. SEO is supported by meta tags and structured navigation. Technical risks include missing DNSSEC and lack of visible security headers, which could be addressed to improve resilience and 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.
