Risk levelHigh

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

The website www.chomutov.cz serves as the official online portal for the statutory city of Chomutov in the Czech Republic. It provides comprehensive information and services for citizens, tourists, and local stakeholders, including eGovernment services, tourism guides, public transport, social assistance, and urban development projects. The site is well-structured with clear navigation and consistent branding, targeting local residents and visitors. Technically, it is built on WordPress with modern themes and plugins, ensuring a responsive and user-friendly experience. Security-wise, the site enforces HTTPS with a good SSL configuration but lacks some security headers and explicit privacy and cookie policies, which are important for compliance and user trust. The absence of WHOIS data reduces transparency and trust slightly, though the site appears legitimate and professionally maintained. Overall, the website demonstrates a solid digital presence for a municipal government but should improve privacy compliance and security headers to enhance trust and regulatory adherence.

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

10 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. 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"

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

Chomutov's official website positions itself as a central hub for municipal services and tourism promotion, reflecting a government entity focused on citizen engagement and regional development. The business model is public service-oriented, with no commercial transactions but extensive information dissemination and digital service facilitation. The site links to multiple related subdomains and partner portals, indicating a well-integrated digital ecosystem. The target audience includes local citizens, tourists, and community organizations. The site’s content and structure suggest a medium-sized municipal operation with a focus on transparency and accessibility. The lack of detailed WHOIS data is unusual for a government domain and may warrant further investigation. The website's partnership ecosystem includes tourism, open data, and social services portals, supporting a comprehensive municipal service offering.

Security posture

The website benefits from HTTPS encryption and uses a recent WordPress version, which is positive for security. However, the absence of key security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options indicates room for improvement in hardening the site against common web attacks. No exposed sensitive data or vulnerable libraries were detected in the provided content. The site lacks explicit privacy and cookie policies, which are critical for GDPR compliance and user trust. There is no visible incident response or security contact information, which is a gap in security governance. The presence of a third-party tracking script (ardalio.com) suggests user analytics but raises privacy considerations. Overall, the security posture is moderate but could be significantly enhanced by implementing recommended headers, policies, and transparency measures.

Recommendations

  1. Implement comprehensive privacy and cookie policies with user consent mechanisms to ensure GDPR compliance.
  2. Add security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to improve protection against web vulnerabilities.
  3. Publish clear contact information for security incidents and designate a Data Protection Officer to enhance security governance.
  4. Regularly audit and update WordPress plugins and themes to mitigate potential vulnerabilities.
  5. Increase WHOIS transparency or provide official domain registration information to improve trust and legitimacy perception.

Technical notes

Notes

The website is built on a modern WordPress CMS platform using the Astra theme and WPBakery Page Builder, indicating a flexible and widely supported infrastructure. It leverages Google Fonts and jQuery libraries for enhanced UI/UX. The site is mobile-optimized and demonstrates good SEO practices with proper meta tags and structured content. Performance is moderate, with no major issues detected in the HTML content. However, the site could benefit from improved accessibility features and additional security hardening. Hosting provider details are not disclosed, and WHOIS data is missing, which limits full technical risk assessment. Overall, the technical implementation supports the business needs effectively but has opportunities for 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.
