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

Havel Channel is a Czech Republic based non-profit media platform operated by the Václav Havel Library, providing political interviews, cultural discussions, and podcasts focused on Václav Havel's legacy and related societal topics. The website is professionally designed with good content quality and consistent branding aligned with its parent organization and strategic partners. Technically, the site uses modern web technologies including Google Fonts, SVG icons, and Google Analytics for tracking, hosted under a Czech registrar and name server. Security posture is adequate with HTTPS enabled and no visible sensitive data exposure, but lacks advanced security headers and formal security policies. Privacy compliance is weak due to absence of privacy and cookie policies and no consent mechanism. Overall, the site is trustworthy and serves a niche audience interested in Czech political and cultural discourse.

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

9 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. 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
    • 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.

Breach exposure

Dark web exposure

Add-on

Leaked records that mention havelchannel.cz, from OffSeq Breach.

No leaked records found

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 in cultural and political media, leveraging the Václav Havel Library's reputation and partnerships with philanthropic foundations. Its business model is non-profit focused on educational and cultural content distribution. The target audience is Czech-speaking individuals interested in politics, culture, and history. The site offers a variety of video series, podcasts, and lectures, indicating diversified content streams. Partnerships with Bakala Philanthropy and Karel Komárek Family Foundation enhance credibility and funding. The domain age and registration details align with the organization's recent establishment in 2020, supporting legitimacy.

Security posture

The website demonstrates a basic to moderate security maturity level. HTTPS is enforced, and no sensitive data is exposed in the HTML. However, the absence of security headers such as Content-Security-Policy and X-Frame-Options reduces protection against common web attacks. There is no visible incident response or vulnerability disclosure information, which limits transparency and readiness. The use of Google Analytics introduces moderate user tracking without visible consent mechanisms, posing privacy compliance risks under GDPR. Overall, the security posture is adequate for a non-commercial cultural site but could be improved to meet higher standards.

Recommendations

  1. Publish a comprehensive privacy policy and cookie policy to improve GDPR compliance.
  2. Implement a cookie consent mechanism to inform users and obtain consent for tracking.
  3. Add security headers like Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to enhance protection.
  4. Provide clear incident response and vulnerability disclosure contact information to improve transparency and security readiness.
  5. Review and minimize user tracking to align with privacy best practices and reduce compliance risks.

Technical notes

Notes

The website uses a custom or unknown CMS with a modern tech stack including Google Fonts, SVG icons, and Google Analytics. Hosting is provided by a Czech registrar and name server, ensuring regional consistency. The site is mobile optimized with good navigation and SEO meta tags. Performance is moderate, with no major issues detected. Accessibility is basic but could be enhanced. The lack of visible CMS or frameworks suggests a custom-built solution, which may require ongoing maintenance to avoid technical debt. Overall, the technical infrastructure supports the site's content and audience effectively but could benefit from modernization and security 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.
