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

Schule.at is a leading Austrian digital education platform operated by Education Group GmbH, offering curated educational content, teaching materials, tools, news, and multimedia resources targeted primarily at educators and schools in Austria. The platform is well-branded, professionally designed, and provides comprehensive educational services with a strong focus on quality and relevance. Technically, the site is built on TYPO3 CMS with modern frontend technologies and integrates Matomo analytics for user tracking with privacy considerations. However, the site currently lacks a valid SSL certificate and proper TLS protocol support, which significantly impacts its security posture. Security headers are well implemented, but the absence of HTTPS and modern TLS protocols is a critical vulnerability. Privacy policies and cookie consent mechanisms are present and GDPR compliant, and contact information is clearly provided, enhancing business credibility. Overall, the site is trustworthy and professional but requires urgent improvements in SSL/TLS configuration to ensure secure user interactions.

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

6 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

    • 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

  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.

    • Critical

      Unable to retrieve SSL certificate

      Could not establish secure connection to retrieve certificate information

      What to do: Check if the server is accessible and SSL/TLS is properly configured

  3. 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';…

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 platform holds a strong market position in Austria's education sector, serving as a central hub for educators with a variety of services including news, teaching resources, and educational videos. Its business model revolves around providing quality-assured educational content and tools, supported by a parent company, Education Group GmbH. The presence of partnerships with siwa.at (software provider) and bildungs.tv (video channel) indicates a collaborative ecosystem. The platform targets educators and schools, focusing on digital transformation in education. The content quality and branding consistency support a medium-sized enterprise profile with a clear focus on education. The use of Matomo analytics suggests a moderate level of user tracking balanced with privacy compliance.

Security posture

The website demonstrates a moderate security maturity level with several positive practices such as the use of multiple security headers (X-Frame-Options, X-XSS-Protection, HSTS) and no detected subdomain takeover vulnerabilities. However, the lack of a valid SSL certificate and disabled TLS protocols represent critical security gaps that expose users to risks such as data interception and man-in-the-middle attacks. The absence of OCSP stapling and session resumption mechanisms further limits security and performance. There is no evidence of formal security policies or incident response contacts published on the site. Overall, while some best practices are followed, the critical SSL/TLS issues must be addressed promptly to improve the security posture and user trust.

Recommendations

  1. Obtain and install a valid SSL/TLS certificate to enable HTTPS and protect user data.
  2. Enable modern TLS protocols (TLS 1.2 and TLS 1.3) and disable outdated or insecure protocols.
  3. Implement OCSP stapling to improve certificate revocation checks and reduce latency.
  4. Enable session resumption mechanisms such as session tickets or session cache for better performance and security.
  5. Publish a clear security policy and incident response contact information to enhance transparency and preparedness.

Technical notes

Notes

The website is powered by TYPO3 CMS and runs on PHP 8.2.28 with nginx 1.21.6 as the web server. Frontend technologies include Font Awesome 6 Pro for icons and Swiper.js for interactive sliders. The site uses Matomo for analytics, indicating a preference for privacy-conscious tracking. Performance metrics are not explicitly provided, but the site appears well-structured and mobile-optimized with responsive design. SEO is supported by comprehensive meta tags and Open Graph data. However, the lack of a valid SSL certificate and disabled TLS protocols are significant technical risks. The site uses caching headers with max-age=0, which may impact performance. Overall, the technical infrastructure is modern but requires security improvements to align with best practices.
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.
