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

3 findings rated critical or high. Fix these first.

  1. 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 X-Frame-Options header

      Prevents clickjacking attacks

      What to do: Add "X-Frame-Options: DENY" or "X-Frame-Options: SAMEORIGIN"

  2. GDPR outside view

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

    • 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

  3. 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

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 occupies a niche in the healthcare education sector within the Czech Republic, focusing on medical professionals' continuing education. Its business model revolves around providing accredited courses and training, likely funded or endorsed by the Czech Medical Chamber. The use of official branding and integration with recognized services like Zoom suggests a credible and authoritative position. The absence of detailed business contact information and legal disclosures may limit transparency but does not detract from its educational focus. The platform's partnerships appear limited to technology providers rather than commercial affiliates. Growth potential exists within the professional education market, especially given the increasing demand for online learning solutions.

Security posture

Security practices are adequate but could be enhanced. The site enforces HTTPS and uses a restrictive Content-Security-Policy to limit resource loading to trusted domains. Google reCAPTCHA integration helps mitigate automated abuse. However, the lack of additional security headers such as X-Frame-Options and Strict-Transport-Security represents an area for improvement. No vulnerabilities or exposed sensitive data were detected in the analyzed content. Incident response and security policy information are absent, which could hinder effective communication in case of security events. Overall, the security posture is solid for an educational platform but would benefit from formalized policies and enhanced header configurations.

Recommendations

  1. Publish a comprehensive privacy policy and terms of service to improve legal compliance and user trust.
  2. Implement additional security headers including X-Frame-Options, X-XSS-Protection, and Strict-Transport-Security.
  3. Provide clear contact information including security incident response contacts.
  4. Regularly audit and update third-party libraries to mitigate potential vulnerabilities.
  5. Enhance accessibility features and SEO optimization to improve user experience and discoverability.

Technical notes

Notes

The website is built on a modern JavaScript framework (Vue.js) with Vuetify for UI components, indicating a contemporary and maintainable codebase. It leverages external services such as Google Analytics for tracking and Zoom for video conferencing. The site is hosted with REG-ZONER, a reputable registrar and hosting provider. Performance is moderate with preloading of scripts and responsive design for mobile devices. Some technical debt is evident in partial security header implementation and limited SEO metadata. The absence of a CMS suggests a custom-built solution, which may require dedicated maintenance resources. Overall, the technical infrastructure supports the business needs effectively but has room for optimization and security hardening.
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.
