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.

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 business operates in the education and healthcare sectors, focusing on accredited online courses for nurses. Its business model revolves around paid and free courses, credit accumulation, and monthly limited-time packages. The platform has a community of over 14,500 nurses, indicating a solid user base and market penetration in Slovakia. The company was founded in 2021, aligning with the domain registration date. The website leverages testimonials and accreditation as trust signals but lacks publicly visible detailed company registration or VAT information. Marketing and analytics are managed via Google Tag Manager and CookieYes, with some advertising through Google Ads. The platform's competitive advantage lies in its accredited, flexible, and accessible nursing education offerings.

Security posture

The website enforces HTTPS and DNSSEC, uses anti-spam plugins, and integrates Google reCAPTCHA, reflecting a proactive approach to security. However, it lacks explicit security policies, incident response contacts, and vulnerability disclosure mechanisms. No critical vulnerabilities or exposed sensitive data were detected in the provided content. The absence of some HTTP security headers and formal security documentation suggests room for improvement in security maturity. Privacy compliance is limited, with no visible privacy policy or terms of service, which may pose compliance risks under GDPR. Overall, the security posture is good but could be enhanced by formalizing policies and adding advanced security controls.

Recommendations

  1. Publish a comprehensive privacy policy and terms of service to improve GDPR compliance and user trust.
  2. Implement additional HTTP security headers such as Content-Security-Policy, X-Content-Type-Options, and X-Frame-Options.
  3. Create and publish a security policy and incident response contact information to enhance transparency and preparedness.
  4. Add a vulnerability disclosure policy or security.txt file to encourage responsible reporting of security issues.
  5. Enhance accessibility features to meet higher standards and improve user experience for all users.

Technical notes

Notes

The website is built on a modern WordPress CMS with Elementor page builder, utilizing common libraries such as jQuery, Bootstrap, FontAwesome, and Swiper.js for UI components. Google Tag Manager and CookieYes are used for analytics and cookie consent management. Hosting is via Websupport with DNSSEC enabled, indicating a secure DNS setup. Performance is moderate with good mobile optimization and SEO practices. The site uses CleanTalk for anti-spam protection and Google reCAPTCHA for bot mitigation. Technical debt appears low, but the site could benefit from enhanced security headers and formal documentation. Overall, the technical infrastructure supports a stable and user-friendly online education platform.
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.
