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

9 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

      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

    • High

      Third-party services without privacy policy

    • High

      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

The institution operates as a public educational entity focused on children with disabilities, positioning itself as a key provider in this specialized sector within the Czech Republic. Its business model revolves around public education and support services, with a medium-sized operational scale. The website reflects a consistent brand and provides comprehensive information about its services, target audience, and educational offerings. Partnerships with platforms like Edookit and presence on Facebook indicate a connected ecosystem. The lack of WHOIS data and explicit contact details online suggests potential areas for transparency improvement. The institution's market position is stable within its niche, with growth potential through enhanced digital presence and outreach.

Security posture

The website demonstrates a mature security posture with HTTPS enforced and integration of Google reCAPTCHA v3 to protect forms from abuse. Cookie consent is implemented in compliance with GDPR, enhancing privacy protection. However, the absence of visible security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options is a gap that could be addressed to improve defense-in-depth. No vulnerabilities or exposed sensitive data were detected in the provided content. The lack of explicit incident response or security policy pages limits transparency on security governance. Overall, the site is secure for its purpose but could benefit from additional security hardening and clearer security documentation.

Recommendations

  1. Implement and configure security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to enhance protection against common web attacks.
  2. Publish explicit security and incident response policies to improve transparency and trust.
  3. Enhance WHOIS data visibility or ensure domain registration details are publicly accessible to improve legitimacy verification.
  4. Add clear company contact emails and phone numbers on the website for better user support and credibility.
  5. Regularly update third-party libraries and monitor for vulnerabilities to maintain security posture.

Technical notes

Notes

The website uses a modern and diverse technology stack including jQuery, Nette Framework for AJAX and forms, Flatpickr for date picking, Slick slider for UI carousels, and Tippy.js for tooltips. Google Tag Manager and reCAPTCHA v3 are integrated for analytics and bot protection respectively. The site loads external CSS and JS from reputable CDNs, ensuring performance and reliability. Mobile optimization and accessibility are well addressed, with responsive design and ARIA labels. Performance is moderate, with potential improvements in caching and resource optimization. No CMS is explicitly detected, suggesting a custom or framework-based solution. Hosting provider details are not evident from the content. Overall, the technical implementation is solid with room for incremental improvements in security headers and performance tuning.
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.
