Their website reflects a professional and well-structured digital presence, leveraging WordPress CMS and modern web technologies to deliver content and services effectively.

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

8 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 Privacy Policy found

      GDPR requires a clear and accessible privacy policy

      What to do: Add a comprehensive privacy policy page and link to it prominently

    • High

      Missing Strict-Transport-Security header

      Forces HTTPS connections

      What to do: Add "Strict-Transport-Security: max-age=31536000; includeSubDomains; preload"

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

CEDU operates as an essential entity within the education sector, focusing on democratic education and civic responsibility. Its business model is non-profit, providing training, resources, and support to schools across the Czech Republic. The organization benefits from accreditation by the Ministry of Education (MŠMT) and has a broad network of partner schools and consultation centers. Testimonials from school directors and a visible social media presence enhance its credibility. The website's content quality and navigation support user engagement, targeting educators and school administrators. Revenue streams likely include course fees and grants. The organization demonstrates growth through its extensive school network and regular events. No direct commercial partnerships or subsidiaries were identified from the website data.

Security posture

The website demonstrates a mature security posture with mandatory HTTPS encryption and secure handling of contact forms. However, the absence of key security headers such as Content-Security-Policy, X-Frame-Options, and X-XSS-Protection represents an area for improvement. No vulnerabilities or exposed sensitive data were detected in the HTML content. The use of reputable third-party services like Google Analytics and Mailchimp is noted, but regular audits of these integrations are recommended to mitigate supply chain risks. The lack of a published security policy or incident response information suggests limited transparency in security governance. Overall, the site is secure for its purpose but could enhance defenses and compliance transparency.

Recommendations

  1. Implement comprehensive security headers (Content-Security-Policy, X-Frame-Options, X-XSS-Protection) to enhance protection against common web attacks.
  2. Introduce an explicit cookie consent banner/mechanism to comply fully with GDPR and improve user privacy transparency.
  3. Publish a clear security policy and incident response plan on the website to demonstrate security governance and readiness.
  4. Regularly review and update third-party scripts and plugins to avoid vulnerabilities from outdated components.
  5. Enhance accessibility features to improve inclusivity and comply with best practices.

Technical notes

Notes

The website is built on WordPress CMS with a modern tech stack including Bootstrap for responsive design, jQuery for scripting, and Google services for analytics and mapping. The site loads multiple asynchronous scripts to optimize performance. SEO is supported by proper meta tags, Open Graph data, and JSON-LD structured data. Mobile optimization is good, with responsive navigation and layout. The site uses a custom theme and includes plugins for contact forms, lightbox galleries, and newsletter integration. Performance is moderate, with potential improvements in script loading and caching. Accessibility is basic but could be enhanced. Hosting appears stable and consistent with the Czech domain registrar REG-INTERNET-CZ. Overall, the technical infrastructure supports the organization's digital goals effectively.
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.
