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

Den pro školu is a Czech non-profit educational initiative supported by Nadace České spořitelny, aiming to connect teachers with volunteers from various professional fields to enrich classroom learning. The website presents a well-structured, content-rich platform with clear calls to action for teachers and volunteers, supported by testimonials and governmental endorsements. Technically, the site uses modern web technologies including the GEM CMS platform, Google Tag Manager for analytics, and is hosted on Erste Group's CDN infrastructure. Security posture is good with HTTPS enforced and no visible vulnerabilities, though explicit security headers could be improved. Privacy compliance is basic with a cookie consent mechanism but lacks a clearly accessible privacy policy page. WHOIS data is unavailable, likely due to privacy protection, which slightly reduces transparency but is common for non-profit entities. Overall, the site is professional, trustworthy, and serves its educational mission effectively.

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

5 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

      Third-party services without privacy policy

      Detected services: Google Analytics, Facebook, LinkedIn, YouTube, Cloudflare

      What to do: Document all third-party data sharing in your privacy policy

  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"

  3. SSL/TLS

    TLS encrypts the connection and proves the site is really yours. Weak or expiring certificates trigger browser warnings and put traffic at risk.

    • High

      Weak Protocols Supported

      Server supports weak protocols: TLSv1.1

      What to do: Disable TLS 1.0, TLS 1.1, and all SSL versions

      • CWE-327
      • OWASP A04:2025
      • ASVS V12.1.1

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
  • 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 program operates in the non-profit and education sectors, targeting primary and secondary schools in the Czech Republic. It leverages partnerships with Nadace České spořitelny and governmental bodies to enhance credibility and reach. The business model is based on volunteer engagement without financial transactions for teachers, supported by foundation funding. The website's content and structure indicate a mature digital presence with moderate size and consistent branding. The absence of direct contact details on the main page suggests a controlled communication channel, possibly to manage volunteer-teacher interactions through the platform. The partnership ecosystem includes the foundation and government, enhancing legitimacy and potential for growth.

Security posture

The website demonstrates a solid security foundation with HTTPS and use of Google Tag Manager for controlled script deployment. No exposed sensitive data or vulnerable libraries were detected in the HTML content. However, explicit security headers such as Content-Security-Policy and X-Frame-Options are not evident in the provided data, which could be improved to mitigate risks like clickjacking or cross-site scripting. The cookie consent mechanism indicates awareness of privacy regulations, but the lack of a visible privacy policy page is a compliance gap. Incident response and vulnerability disclosure information are absent, which is typical for non-profit sites but could be enhanced for transparency. Overall, the security posture is good but could benefit from additional headers and documented policies.

Recommendations

  1. Publish a clear and comprehensive privacy policy page accessible from the homepage.
  2. Implement and verify security headers including Content-Security-Policy, X-Frame-Options, and Referrer-Policy.
  3. Provide explicit contact information for data protection officer or privacy inquiries to improve GDPR compliance.
  4. Add an incident response or vulnerability disclosure page to enhance transparency and trust.
  5. Regularly audit third-party scripts and dependencies to ensure no vulnerabilities are introduced.

Technical notes

Notes

The website is built on the GEM CMS platform, utilizing modern JavaScript modules and CSS for responsive design. It leverages Google Tag Manager for analytics and tracking, and hosts assets on Erste Group's CDN for performance. The site is mobile optimized with good accessibility features such as skip links and ARIA labels. Performance is moderate, with some spinner placeholders indicating dynamic content loading. The use of web fonts and optimized images contributes to a professional look. There is no evidence of legacy or vulnerable libraries. Opportunities exist to improve SEO by adding structured data (JSON-LD) and enhancing meta tags. Technical risks are low but monitoring third-party scripts is advised.
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.
