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

The website www.priserkyvhlave.cz is an educational platform in Czech language focused on teaching about monsters through interactive games and resources, primarily targeting schools and children. It is a project supported and co-financed by the European Union and the Czech Ministry of Interior, indicating a non-commercial, public service nature. The site uses modern web technologies such as React and Next.js, providing a good user experience with responsive design and clear navigation. However, the site lacks visible privacy, cookie, and terms of service policies, and no contact information is provided, which limits transparency and user trust. From a technical perspective, the site is built on a modern JavaScript framework with client-side rendering and moderate performance. No analytics or tracking scripts were detected, suggesting minimal user tracking. Security posture is limited due to the absence of security headers and no visible SSL configuration details. The WHOIS data for the domain is unavailable, likely due to privacy protection or domain registration issues, which negatively impacts the trustworthiness assessment. Overall, the website is safe and suitable for general audiences, with no adult or explicit content detected. The lack of WHOIS transparency and privacy policies are the main concerns. Strategic recommendations include implementing comprehensive privacy and cookie policies, improving security headers, providing clear contact and incident response information, and verifying domain registration details to enhance trust and compliance.

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

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 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. 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"

    • 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';…

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 operates as a niche educational resource funded by governmental and EU bodies, targeting schools and children interested in folklore and monster-related educational content. Its business model is non-commercial, focusing on public education and integration support. The partnership with the Integration Center Prague and funding from the EU and Czech Ministry of Interior provide credibility and a stable support ecosystem. The site’s competitive advantage lies in its interactive approach to education and alignment with official integration and educational initiatives. Growth potential depends on expanding educational content and school engagement. The absence of commercial elements and tracking tools aligns with its public service mission.

Security posture

The website demonstrates a basic security posture with HTTPS likely enabled (inferred from URL scheme), but no explicit security headers were detected in the provided data. There is no evidence of exposed sensitive data or vulnerable libraries, but the lack of privacy and cookie policies, absence of contact information for incident response, and missing WHOIS transparency are notable compliance and trust gaps. The site does not appear to collect user data via forms or analytics, reducing risk exposure. However, the security score is moderate due to missing best practices such as security headers and documented policies. Incident response readiness and data protection officer information are not present, indicating room for improvement in security governance.

Recommendations

  1. Implement and publish comprehensive privacy and cookie policies to ensure GDPR compliance and user transparency.
  2. Add security headers including Content-Security-Policy, X-Frame-Options, X-Content-Type-Options, and Strict-Transport-Security to enhance protection against common web attacks.
  3. Provide clear contact information and establish an incident response channel to improve security transparency and readiness.
  4. Verify and disclose domain registration details to improve trustworthiness and reduce suspicion related to privacy-protected WHOIS data.
  5. Consider adding accessibility improvements and SEO enhancements to increase reach and usability.

Technical notes

Notes

The website is built using Next.js, a modern React framework, indicating a contemporary technology stack with server-side rendering capabilities. The site uses multiple JavaScript chunks and CSS files for styling, suggesting modular and maintainable code. Performance is moderate with deferred script loading and prefetching of pages, supporting good user experience. Mobile optimization is good, with viewport meta tags and responsive design elements. No CMS or hosting provider information is directly detectable. The absence of analytics and tracking scripts suggests minimal data collection. Technical risks include missing security headers and unknown SSL configuration, which should be addressed to improve security posture.
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.
