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

Jednota školských informatiků (JSI) is a Czech non-profit association dedicated to supporting the effective use of digital technologies in education, primarily targeting schools and educators. Established in 2002, JSI fosters communities of teachers and ICT enthusiasts to promote digital competencies and informatics thinking among children and students. The website serves as an informational and community platform, providing news, events, and resources related to digital education in the Czech Republic. Technically, the site is built on WordPress using the Divi theme, with standard JavaScript libraries such as jQuery and Swiper.js for interactive elements. The site is moderately optimized for performance and mobile devices but lacks advanced accessibility features and comprehensive SEO optimizations. Security-wise, the website uses HTTPS but lacks several important security headers and explicit incident response contacts, which could be improved to enhance trust and compliance. Privacy and cookie policies are not present, indicating a gap in GDPR compliance. Overall, the site is trustworthy and professional in its domain but would benefit from enhanced privacy, security, and compliance measures.

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

    • 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. 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';…

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

JSI occupies a niche in the Czech educational non-profit sector, focusing on digital transformation in schools. Its competitive advantage lies in its long-standing presence since 2002 and its active engagement with teacher communities and educational authorities. The business model is membership-based, supported by annual fees and project funding. The target customers are educators, school ICT coordinators, and educational institutions across the Czech Republic. Growth indicators include active blog updates and community events. Partnerships appear limited but include collaboration with educational platforms and regional authorities. Strategic observations suggest opportunities to expand digital training offerings and formalize partnerships to increase influence and funding.

Security posture

The website demonstrates a basic security posture with HTTPS enabled, ensuring encrypted communication. However, the absence of key security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options reduces protection against common web attacks like clickjacking and MIME sniffing. No visible vulnerability disclosure or incident response information is provided, which limits transparency and readiness for security incidents. The WordPress platform and Divi theme are widely used but require regular updates to mitigate vulnerabilities. No analytics or tracking scripts reduce privacy risks but also limit user behavior insights. Overall, the security maturity is moderate but can be significantly improved by implementing recommended headers, policies, and incident response mechanisms.

Recommendations

  1. Implement comprehensive privacy and cookie policies with clear GDPR compliance statements.
  2. Add security headers including Content-Security-Policy, X-Frame-Options, X-Content-Type-Options, and Referrer-Policy.
  3. Establish and publish an incident response contact channel, such as security@ or abuse@ email addresses.
  4. Regularly update WordPress core, themes, and plugins to maintain security.
  5. Enhance accessibility features to improve usability and compliance with standards.

Technical notes

Notes

The website is built on a mature and popular CMS platform, WordPress, using the Divi theme which provides flexible design and layout capabilities. The use of jQuery and Swiper.js indicates reliance on established JavaScript libraries for UI interactions. Performance is moderate, with some optimization opportunities in CSS and JavaScript delivery. Mobile responsiveness is good, ensuring usability across devices. SEO is basic with standard meta tags but lacks advanced structured data or Open Graph tags for social media optimization. No analytics or tracking scripts were detected, which may limit marketing insights but improves privacy. Hosting appears stable with Czech-based registrar and name servers. Technical risks include potential outdated plugins or themes and missing security headers that could expose the site to attacks.
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.
