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

The website www.revnice.cz serves as the official online presence of the municipal government of Řevnice, Czech Republic. It provides residents and visitors with comprehensive information about local government operations, cultural and sporting events, administrative services, and community resources. The site is well-structured with clear navigation and includes features such as an event calendar, e-podatelna for electronic submissions, and tourist information, positioning it as a key resource for the local community. Technically, the site employs a modern technology stack including jQuery, jQuery UI, and the Public4u CMS platform. It integrates mapping services via the Mapy.cz API and uses Smartlook for user behavior analytics. The site is mobile-optimized and accessible, with a responsive design and voice assistant features enhancing usability. However, some security best practices such as the implementation of security headers are not evident. From a security perspective, the site enforces HTTPS and uses secure form submissions, but lacks visible security headers and explicit security or incident response policies. The absence of WHOIS data for the domain raises concerns about domain registration transparency, although the content and official indicators suggest legitimacy. Cookie consent mechanisms and privacy policies are present, indicating a basic level of privacy compliance. Overall, the website is a functional and professional municipal portal with good content quality and user experience. The main risks relate to domain registration opacity and some missing security hardening measures. Strategic improvements in security headers, domain registration transparency, and explicit security policies would enhance 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.

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

  2. 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.

    • Critical

      Unable to retrieve SSL certificate

      Could not establish secure connection to retrieve certificate information

      What to do: Check if the server is accessible and SSL/TLS is properly configured

  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 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';…

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 municipal website positions itself as an essential local government service platform, targeting residents, local businesses, and visitors. Its business model is public service oriented, focusing on information dissemination and community engagement rather than commercial revenue. The site leverages partnerships with local organizations and service providers, as evidenced by linked domains and references to EU projects. The presence of event calendars and cultural information suggests active community involvement. The use of a specialized CMS (Public4u) and integration with local mapping services indicates a tailored approach to municipal digital services. Growth indicators include regular updates and integration of modern web features such as voice assistance and mobile optimization.

Security posture

The website demonstrates a moderate security posture with HTTPS enforced and secure form handling. However, the lack of security headers such as Content Security Policy (CSP), HTTP Strict Transport Security (HSTS), and X-Frame-Options reduces its defense-in-depth capabilities. No explicit incident response or vulnerability disclosure information is provided, which limits transparency and preparedness. The use of third-party analytics (Smartlook) introduces moderate user tracking, but cookie consent mechanisms are in place. The missing WHOIS data for the domain is a significant concern, potentially indicating privacy protection or registration issues that could affect trust. Overall, the site would benefit from enhanced security policies, improved header configurations, and clearer incident response channels.

Recommendations

  1. Implement comprehensive security headers including CSP, HSTS, and X-Frame-Options to improve security posture.
  2. Verify and publish domain WHOIS information to enhance transparency and trustworthiness.
  3. Develop and publish explicit security and incident response policies accessible from the website.
  4. Regularly update third-party libraries and CMS to mitigate vulnerabilities.
  5. Enhance privacy compliance by detailing data retention policies and providing clearer user data controls.

Technical notes

Notes

The website uses a stable and recognized CMS platform (Public4u) combined with popular JavaScript libraries such as jQuery and jQuery UI, ensuring compatibility and ease of maintenance. Integration with Mapy.cz API provides robust mapping functionality tailored to local needs. The site is mobile-optimized and includes accessibility features like a voice assistant, indicating attention to diverse user needs. Performance is moderate, with no major issues detected in the HTML structure or resource loading. However, the absence of security headers and incomplete WHOIS data suggest areas for technical improvement. The use of Smartlook analytics indicates moderate user tracking, which should be balanced with privacy considerations.
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.
