Security score

Risk levelMedium

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

The website rebokiga.de represents the Regenbogenkindergarten, a specialized educational institution in Tuttlingen, Germany, focusing on children with intellectual, physical, and motor disabilities. The institution provides small group care and special education services, positioning itself as a local leader in inclusive early childhood education. The website is professionally designed with clear navigation and provides comprehensive contact information, privacy, and cookie policies, reflecting a commitment to user trust and compliance. Technically, the site uses legacy JavaScript libraries such as jQuery 1.10.2 and includes common UI components like datepickers and sliders, but lacks modern security headers and updated libraries, which could pose risks. Security posture is moderate with cookie consent implemented but no explicit security or incident response policies found. Overall, the site is safe, family-friendly, and trustworthy, but could benefit from technical modernization and enhanced security practices.

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

3 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 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 Consent Banner found

      GDPR requires explicit consent for non-essential cookies

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

  3. SSL/TLS

    TLS encrypts the connection and proves the site is really yours. Weak or expiring certificates trigger browser warnings and put traffic at risk.

    • High

      Weak Protocols Supported

      Server supports weak protocols: TLSv1.1

      What to do: Disable TLS 1.0, TLS 1.1, and all SSL versions

      • CWE-327
      • OWASP A04:2025
      • ASVS V12.1.1

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

Regenbogenkindergarten operates as a small, essential entity within the education sector, targeting families of children with special needs. Its business model is non-profit or publicly funded educational service provision. The website is maintained or developed by Advantic Systemhaus GmbH, indicating a partnership or parent company relationship. The institution's competitive advantage lies in its specialized focus and small group settings. No evident revenue streams or commercial activities are visible on the site. The partnership ecosystem includes Advantic Systemhaus GmbH as a technology and service provider. Growth indicators are not explicit, but recent news updates suggest active community engagement.

Security posture

The security maturity level is moderate. The site uses HTTPS (assumed but not explicitly confirmed), has a cookie consent mechanism, and no exposed sensitive data was found. However, the use of outdated JavaScript libraries (jQuery 1.10.2) introduces potential vulnerabilities. No security headers such as Content Security Policy or HSTS were detected. There is no visible incident response or security policy documentation. GDPR compliance is indicated by the privacy and cookie policies. The absence of a vulnerability disclosure or security.txt file limits transparency. Overall, the security posture is adequate for a small educational site but requires improvements to mitigate risks.

Recommendations

  1. Upgrade all JavaScript libraries, especially jQuery, to the latest secure versions to reduce vulnerability exposure.
  2. Implement comprehensive security headers including Content Security Policy, HSTS, X-Frame-Options, and X-Content-Type-Options.
  3. Publish explicit security and incident response policies to enhance transparency and preparedness.
  4. Ensure HTTPS is enforced site-wide with strong SSL/TLS configurations.
  5. Consider adding a vulnerability disclosure policy or security.txt file to encourage responsible reporting and improve trust.

Technical notes

Notes

The website is built on a custom or proprietary CMS platform with a technology stack including jQuery 1.10.2, jQuery UI Datepicker, Highslide JS for image galleries, and Flexslider for slideshows. The HTML uses ISO-8859-1 charset and includes responsive meta viewport tags, but mobile optimization is basic. The site loads multiple CSS files and JavaScript libraries from its own domain, indicating self-hosted assets. Performance is moderate with no explicit speed optimizations detected. Accessibility features are basic with skip links and landmarks but no ARIA roles beyond standard HTML5. SEO is basic with meta tags but no Open Graph or JSON-LD structured data present. The site is well-structured with clear navigation menus and content hierarchy.
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.
