0–100, higher is better. How it is calculated

The website www.vzdelavani-dh.cz serves as an e-learning platform dedicated to the education of voluntary firefighters affiliated with the Sdružení hasičů Čech, Moravy a Slezska (SH ČMS) in the Czech Republic. It offers multimedia courses, interactive tests, and performance tracking to facilitate knowledge acquisition and verification. The platform targets members of SH ČMS and aims to provide an accessible and intuitive online learning experience. The website branding and content align well with the stated mission, although no detailed company founding or registration data is provided. From a technical perspective, the site employs common web technologies including Bootstrap, jQuery, Font Awesome, and Google Analytics for tracking user interactions. The design is responsive and user-friendly, with clear navigation and relevant content. However, the absence of detected security headers and privacy policies indicates room for improvement in security and compliance maturity. The WHOIS data is unavailable, which limits the ability to verify domain legitimacy and age, impacting trustworthiness assessments. Security posture is moderate; HTTPS is assumed but not explicitly confirmed in the data. No critical vulnerabilities or exposed sensitive data were found in the HTML content. The site lacks privacy and cookie policies, which is a compliance gap under GDPR. No contact information for security incidents or data protection officers is provided. Overall, the site appears safe and professional but would benefit from enhanced security controls and transparency. The overall risk is moderate with no immediate red flags, but the lack of WHOIS data and privacy compliance measures suggest the need for strategic improvements to bolster trust and regulatory adherence.

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

10 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

  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. Network security

    Services reachable from the internet are the first thing attackers probe. Anything open that does not need to be should be closed.

    • Critical

      Critical Service Exposed: MySQL

      Port 3306 (MySQL) is publicly accessible - MySQL - Database server

      What to do: Immediately restrict access to MySQL using firewall or VPN

      • NIS2 21(2)(e)
      • IR 2024/2690 6.7.2(f): Implementing Regulation (EU) 2024/2690, Annex point 6.7.2(f): Network security
      • NIST CM-7: NIST SP 800-53 Rev. 5 CM-7: Least Functionality
      • NIST SC-7: NIST SP 800-53 Rev. 5 SC-7: Boundary Protection

  4. 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 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 · found on this site
  • 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 educational market serving voluntary firefighters in the Czech Republic, leveraging e-learning to enhance training efficiency. Its competitive advantage lies in its specialized content tailored to SH ČMS members and integration of multimedia and testing features. The business model is primarily service-oriented, focusing on education delivery rather than commercial sales. Revenue streams are not disclosed but likely stem from organizational funding or membership fees. The target customer segment is well-defined and localized. Growth potential depends on expanding course offerings and improving digital maturity. Partnerships with SH ČMS and related organizations (e.g., dh.cz) support credibility. Strategic observations include the need for improved compliance documentation and enhanced security posture to support sustainable growth and trust.

Security posture

The current security maturity level is moderate. The site uses HTTPS (assumed) and Google Analytics for tracking, but lacks visible security headers such as Content Security Policy, HSTS, or X-Frame-Options. No vulnerabilities or exposed sensitive data were detected in the HTML content. Compliance gaps include missing privacy and cookie policies, absence of incident response contact information, and no evidence of a data protection officer. The site does not appear to implement advanced security frameworks or certifications. Incident response readiness is unclear. Recommendations include implementing security headers, publishing privacy and cookie policies, and establishing clear security contact channels. The security culture appears basic but can be improved with governance and transparency measures.

Recommendations

  1. Implement comprehensive privacy and cookie policies to ensure GDPR compliance.
  2. Add security headers such as Content Security Policy, HSTS, and X-Frame-Options to enhance protection.
  3. Publish clear contact information for security incidents and designate a data protection officer.
  4. Verify and publish WHOIS domain registration details to improve trust and legitimacy.
  5. Enhance accessibility features and SEO optimization to improve user experience and reach.

Technical notes

Notes

The website is built on a standard technology stack including Bootstrap for responsive design, jQuery for scripting, and Font Awesome for icons. Google Analytics is used for user behavior tracking. The HTML structure is valid and supports modern browsers with fallbacks for older IE versions. Performance is moderate with asynchronous loading of analytics scripts. No CMS or hosting provider information is evident. The site lacks advanced technical SEO and accessibility features but provides a clean and navigable interface. Technical risks include missing security headers and incomplete compliance documentation, which could impact user trust and regulatory adherence.
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.
