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. 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

  3. Network security

    Services reachable from the internet are the first thing attackers probe. Anything open that does not need to be should be closed.

    • High

      High-Risk Service Exposed: FTP

      Port 21 (FTP) is publicly accessible - FTP - Often unencrypted file transfer

      What to do: Consider restricting access to FTP or implementing strong authentication

      • NIS2 21(2)(e)
      • IR 2024/2690 6.7.2(f): Implementing Regulation (EU) 2024/2690, Annex point 6.7.2(f): Network security
      • NIST CM-7: NIST SP 800-53 Rev. 5 CM-7: Least Functionality
      • NIST SC-7: NIST SP 800-53 Rev. 5 SC-7: Boundary Protection

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 organization operates within the education and non-profit sectors, focusing on Catholic schooling in Berlin and Brandenburg. Its market position is strong regionally, supported by a network of partner schools and the Archdiocese. The business model is non-commercial, emphasizing educational quality and community engagement. Revenue streams likely include public funding and church support. The website supports recruitment and communication with stakeholders, indicating active growth and engagement. Partnerships with multiple school domains reinforce a collaborative ecosystem. The absence of commercial advertising and minimal tracking reflects a privacy-conscious approach consistent with its mission.

Security posture

The website demonstrates a mature security posture with enforced HTTPS, GDPR-compliant cookie consent with opt-in and blocking of external cookies until consent, and session cookie management. However, it lacks published security policies, incident response contacts, and vulnerability disclosure mechanisms, which are important for transparency and trust. No security headers were detected in the provided data, suggesting room for improvement. No vulnerabilities or exposed sensitive data were found. The site uses well-known CMS and libraries but should maintain regular updates to mitigate risks. Overall, security is adequate but could be enhanced with formal policies and additional technical controls.

Recommendations

  1. Publish a dedicated security policy page outlining security practices and commitments.
  2. Provide clear incident response contact information, such as a security@ or abuse@ email address.
  3. Implement and publish a vulnerability disclosure policy or security.txt file to encourage responsible reporting.
  4. Add security headers like Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security to improve protection.
  5. Regularly audit and update third-party scripts and CMS components to prevent vulnerabilities.

Technical notes

Notes

The website is built on Joomla CMS, leveraging jQuery, Webcomponents.js, and Bootstrap for UI components like carousels and responsive navigation. The GDPR cookie consent plugin is well integrated with opt-in and category controls. The site is mobile-optimized with responsive design and accessible navigation. Performance is moderate, with no major issues detected. SEO is supported by proper meta tags and structured content. No analytics or advertising scripts were detected, indicating a privacy-first approach. Hosting provider details are not explicit but domain name servers suggest professional hosting. The site could benefit from enhanced accessibility features 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.
