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.

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 Cookie Policy found

      GDPR requires clear information about cookie usage

      What to do: Add a dedicated cookie policy explaining cookie usage and purposes

  2. Email security

    SPF, DKIM and DMARC stop others sending email that looks like it comes from your domain, a common route to phishing and invoice fraud.

    • Critical

      No email authentication configured

      Domain is vulnerable to email spoofing

      What to do: Implement SPF, DKIM, and DMARC immediately

  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 Strict-Transport-Security header

      Forces HTTPS connections

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

      • CWE-319
      • OWASP A04:2025
      • ASVS V3.4.1
    • 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

VU3V.cz operates within the education sector, focusing on lifelong learning for seniors. Its business model combines virtual and physical learning environments, enhancing accessibility for geographically dispersed learners. The institution benefits from its affiliation with a reputable university, which strengthens its market position and trustworthiness. The presence of testimonials, comprehensive contact information, and social media engagement indicates a mature and user-focused operation. The platform's growth potential lies in expanding virtual offerings and regional consultation centers.

Security posture

The website enforces HTTPS and implements session management and cookie consent mechanisms, reflecting a baseline security posture. However, the absence of explicit security headers and publicly available security policies or incident response contacts suggests areas for improvement. No vulnerabilities or exposed sensitive data were detected in the content. The security maturity is moderate, suitable for an educational portal but requiring enhancements to align with best practices and compliance standards such as GDPR and NIS2.

Recommendations

  1. Implement HTTP security headers like Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to enhance protection against common web attacks.
  2. Publish a dedicated security policy and provide clear incident response contact channels to improve transparency and readiness.
  3. Introduce a security.txt file to facilitate responsible vulnerability disclosure.
  4. Regularly audit and update third-party libraries and dependencies to mitigate risks from known vulnerabilities.
  5. Enhance monitoring and logging capabilities to detect and respond to potential security incidents promptly.

Technical notes

Notes

The website is built on the Moodle LMS platform, utilizing modern JavaScript libraries such as YUI, jQuery, and RequireJS, alongside MathJax for mathematical rendering and UKit for UI components. The site demonstrates good mobile responsiveness and accessibility features, with a moderate performance profile. The technical infrastructure appears stable and well-maintained, though the hosting provider is not explicitly identified. Opportunities exist to modernize certain legacy libraries and optimize performance further. Overall, the technical implementation supports the educational mission 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.
