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

Landesinitiative n-21 Schulen in Niedersachsen online e.V. is a well-established non-profit organization focused on advancing digital education in Lower Saxony, Germany. The initiative offers a variety of projects and services such as the Niedersächsische Bildungscloud, moin.schule, and Schul-Internetradio, targeting schools, educators, and students. It maintains strong partnerships with regional government bodies and educational institutions, reinforcing its credibility and market position. Technically, the website is built on a modern stack including JavaScript, jQuery, Swiper.js, and the NOLIS CMS platform. It is hosted with Cloudflare DNS services and demonstrates good mobile optimization, accessibility, and SEO practices. The site uses HTTPS with excellent SSL configuration and includes a cookie consent mechanism, reflecting a good level of digital maturity. From a security perspective, the site enforces HTTPS and uses cookie consent banners but lacks explicit security headers and a published security policy or incident response contacts. No vulnerabilities or exposed sensitive data were detected. The WHOIS data aligns with the website's educational and regional focus, indicating legitimacy. Overall, the website presents a low risk profile with strong business credibility and good technical implementation. Strategic improvements in security headers and incident response transparency would further enhance its security posture.

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

4 findings rated critical or high. Fix these first.

  1. GDPR outside view

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

    • Critical

      EU business without adequate privacy measures

      EU businesses are subject to strict GDPR requirements

      What to do: Implement comprehensive GDPR compliance including privacy policy, cookie consent, and data protection measures

    • 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

  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
    • High

      Weak SSL Key Length

      SSL certificate uses 384-bit key, which is considered weak

      What to do: Use at least 2048-bit RSA or 256-bit ECC key

      • CWE-326
      • OWASP A04:2025
      • Mozilla TLS: Mozilla Server Side TLS 6.0 intermediate: rsa_key_size 2048

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.
  • 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 as a non-profit educational initiative with a clear focus on digital transformation in schools within Lower Saxony. Its business model revolves around providing digital learning platforms, educational projects, and support services. The initiative benefits from strong governmental and institutional partnerships, which enhance its competitive advantage and market reach. Revenue streams are likely grant and government-funded, typical for non-profit educational entities. The target audience includes schools, educators, and students in the region. The partnership ecosystem is robust, involving multiple government and educational bodies, which supports sustainable growth and influence in the education sector.

Security posture

The website demonstrates a moderate to good security maturity level. HTTPS is enforced with strong SSL configuration, and cookie consent mechanisms are in place, supporting GDPR compliance. However, the absence of security headers such as Content-Security-Policy and X-Frame-Options represents an area for improvement. No incident response or security contact information is published, which could hinder timely vulnerability reporting and response. No known vulnerabilities or exposed sensitive data were found. Overall, the security posture is adequate for a non-profit educational website but could be strengthened by adopting additional security best practices and transparency.

Recommendations

  1. Implement comprehensive security headers including Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security.
  2. Publish a clear security policy and provide incident response contact channels to improve transparency and readiness.
  3. Conduct regular security audits of third-party scripts and CMS components to mitigate potential vulnerabilities.
  4. Enhance privacy compliance by detailing data retention policies and user data handling practices.
  5. Improve advertising transparency by disclosing any tracking or marketing tools if introduced in the future.

Technical notes

Notes

The website uses a modern and stable technology stack with JavaScript, jQuery, Swiper.js for UI components, and TinyMCE for content editing. It is powered by the NOLIS CMS, which appears to be a specialized platform for educational content management. Hosting leverages Cloudflare DNS services, enhancing DNS reliability and security. Performance is moderate with good mobile responsiveness and accessibility features. SEO is well addressed with proper meta tags and structured data (JSON-LD). There is room for improvement in security headers and possibly performance optimization to achieve faster load times.
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.
