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

Česká škola bez hranic z.s. is a Czech non-profit organization dedicated to supporting Czech schools abroad and promoting Czech language and culture internationally. The website serves as a hub for information about their activities including international conferences, language olympiads, translation competitions, webinars, and educational resources. The organization targets Czech expatriates, educators, parents, and children interested in maintaining Czech education outside the Czech Republic. Established in 2009, it holds a reputable position within its niche educational sector. Technically, the website is built on WordPress 6.7.4 using the Gridlove theme and several Meks plugins to enhance functionality. It is hosted on opalstack.com and uses HTTPS with a moderate performance profile. The site is mobile-optimized and has good SEO practices, though accessibility features are basic. Analytics are handled via Jetpack Stats with minimal user tracking. From a security perspective, the site benefits from HTTPS and does not expose sensitive data or use vulnerable libraries visibly. However, it lacks important security headers and does not publish security policies or incident response contacts. Privacy compliance is weak as no privacy or cookie policies are found, and no consent mechanisms are implemented. Contact information is clearly provided, enhancing business credibility. Overall, the website is professional and trustworthy for its audience but would benefit from improved privacy compliance and security hardening. Strategic recommendations include implementing privacy and cookie policies, adding security headers, publishing a security policy with incident response contacts, and regular security audits to maintain 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

13 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

  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
    • Critical

      Critical Service Exposed: PostgreSQL

      Port 5432 (PostgreSQL) is publicly accessible - PostgreSQL - Database server

      What to do: Immediately restrict access to PostgreSQL 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 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 Strict-Transport-Security header

      Forces HTTPS connections

      What to do: Add "Strict-Transport-Security: max-age=31536000; includeSubDomains; preload"

      • CWE-319
      • OWASP A04:2025
      • ASVS V3.4.1

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 · 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 organization operates in the education and non-profit sectors, focusing on Czech language education abroad. Its business model revolves around community support, event organization, and educational resource provision. The website indicates a stable market position with a clear target audience of Czech expatriates and educators. Revenue streams likely include donations, event fees, and sponsorships. The partnership with platba.csbh.cz for payment processing suggests organized fundraising or fee collection. The organization maintains a consistent brand and content quality, supporting growth and engagement within its niche. The presence of multiple educational initiatives and conferences indicates active community involvement and strategic outreach.

Security posture

The website demonstrates a moderate security maturity level with HTTPS enabled and no visible sensitive data exposure. However, the absence of security headers such as Content-Security-Policy and X-Frame-Options reduces protection against common web attacks. No vulnerability disclosure or incident response information is published, which limits transparency and readiness. Privacy compliance gaps, including missing privacy and cookie policies, expose the organization to regulatory risks under GDPR. The use of well-known WordPress plugins and themes reduces risk but requires ongoing monitoring for vulnerabilities. Overall, the security posture is functional but requires enhancements to meet best practices and compliance standards.

Recommendations

  1. Implement and publicly publish a comprehensive privacy policy and cookie policy with GDPR compliance details.
  2. Add security headers including Content-Security-Policy, X-Frame-Options, X-Content-Type-Options, and Referrer-Policy to enhance protection.
  3. Create and publish a security policy and incident response contact information (e.g., security@ or abuse@ email addresses).
  4. Introduce a cookie consent mechanism to comply with privacy regulations and improve user trust.
  5. Regularly audit and update WordPress plugins and themes to mitigate vulnerabilities and maintain security posture.

Technical notes

Notes

The website is built on a modern WordPress CMS version 6.7.4 with a professional theme (Gridlove) and multiple Meks plugins providing flexible shortcodes, social widgets, and advertising widgets. It uses jQuery and MediaElement.js for frontend functionality. Hosting is provided by opalstack.com, a reputable hosting provider. Performance is moderate with deferred loading of emoji scripts and optimized images. The site is mobile responsive and SEO optimized with proper meta tags and structured navigation. Accessibility features are basic and could be improved. No critical technical debt or outdated libraries were detected, but security headers are missing, which is a technical risk. Overall, the infrastructure is solid but can benefit from security and privacy enhancements.
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.
