Priority findings

5 findings rated critical or high. Fix these first.

  1. Network security

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

    • Critical

      Port 445 (SMB) is publicly accessible - SMB - Windows file sharing, high risk

      What to do: Immediately restrict access to SMB using firewall or VPN

      • 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
    • Critical

      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

    • High

      Weak Protocols Supported

      Server supports weak protocols: TLSv1.1

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

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

  • Security headers: did not complete in this scan.
  • GDPR outside view: did not complete in this scan.
  • 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 · found on this site
  • 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 institution targets adult learners in the Landkreis Harburg region, providing diverse educational offerings that cater to personal development and professional skills enhancement. The business model is public education with a focus on community engagement and lifelong learning. The website supports this with detailed course listings, calendar integration, and user account features. Social media channels and partnerships with local government and educational platforms enhance its ecosystem. The organization maintains a consistent brand and content quality, positioning itself as a reliable regional education provider.

Security posture

The website enforces HTTPS and uses secure form submission methods. Cookie consent is implemented via Klaro, indicating attention to privacy compliance. However, no explicit security headers were detected in the provided data, which could be improved to enhance protection against common web attacks. No vulnerabilities or exposed sensitive data were found. Incident response and security policies are not publicly disclosed, which is common for such institutions but could be enhanced for transparency. Overall, the security posture is good but has room for improvement in headers and policy disclosures.

Recommendations

  1. Implement security headers such as Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security to strengthen web security.
  2. Publish a security policy and incident response plan to improve transparency and preparedness.
  3. Regularly audit third-party scripts and libraries for vulnerabilities and update them timely.
  4. Enhance monitoring and logging to detect and respond to security incidents promptly.
  5. Maintain and update privacy and cookie policies to reflect any changes in data processing.

Technical notes

Notes

The website uses TYPO3 CMS, a robust and widely used content management system, combined with Bootstrap for responsive design and jQuery for client-side scripting. The presence of Klaro for cookie consent and eyeAble for accessibility indicates a focus on compliance and inclusivity. Performance is moderate with standard optimizations. The site is mobile-friendly and accessible, with clear navigation and structured content. Hosting details are not explicit but the domain uses standard name servers. The technical stack is modern and appropriate for the institution's needs, with opportunities to enhance security headers 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.
