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

The website www.revnice.cz serves as the official municipal portal for the town of Řevnice in the Czech Republic. It provides residents and visitors with comprehensive information about local government operations, cultural events, sports activities, public services, and community news. The site targets local citizens and tourists seeking municipal resources and updates. The business model is that of a government service portal, focusing on transparency and community engagement. Technically, the site employs a mix of traditional web technologies 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 website is moderately performant, mobile-optimized, and includes accessibility features such as a voice assistant. SEO and navigation are well implemented, supporting a positive user experience. From a security perspective, the site uses HTTPS and secure forms but lacks visible advanced security headers and explicit security policies. No vulnerabilities or exposed sensitive data were detected in the HTML content. The absence of WHOIS data for the domain reduces trustworthiness, though the official nature of the site and consistent branding mitigate concerns. Cookie consent mechanisms are in place, supporting privacy compliance. Overall, the site is a well-structured municipal resource with good content quality and usability. The primary risk lies in the lack of domain registration transparency and limited visible security policies. Strategic improvements in security headers, domain registration verification, and explicit policy disclosures 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.

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

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

    • High

      No Cookie Consent Banner found

      GDPR requires explicit consent for non-essential cookies

      What to do: Implement a cookie consent banner that appears on first visit

  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"

    • 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

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 website positions itself as the authoritative online presence for the Řevnice municipal government, serving a small local market. Its competitive advantage lies in providing centralized access to government services, local news, event calendars, and community resources. Revenue streams are not applicable as it is a government entity. The target customers are residents, local businesses, and visitors. Growth indicators include active event promotion and integration of digital tools like voice assistance. The partnership ecosystem includes local service providers and the CMS vendor (as4u.cz). The site reflects a stable, community-focused operation with emphasis on transparency and accessibility.

Security posture

The security maturity of the website is moderate. HTTPS is enforced, and forms include hidden fields to support secure data submission. However, the absence of key security headers such as Content Security Policy (CSP), HTTP Strict Transport Security (HSTS), and X-Frame-Options weakens the defense-in-depth posture. No incident response or vulnerability disclosure information is present, indicating limited formal security governance. The use of third-party analytics (Smartlook) introduces moderate tracking but no evident privacy violations. The lack of WHOIS data is a concern for domain legitimacy and trust. Overall, the site would benefit from enhanced security controls, policy transparency, and domain registration clarity.

Recommendations

  1. Implement comprehensive security headers including CSP, HSTS, and X-Frame-Options to improve protection against common web attacks.
  2. Verify and publish domain registration details to enhance trust and legitimacy perception.
  3. Develop and publish explicit security and incident response policies to demonstrate governance maturity.
  4. Regularly audit third-party scripts and analytics tools to minimize privacy risks and ensure compliance.
  5. Enhance privacy disclosures and cookie consent mechanisms to align with GDPR and other regulations.

Technical notes

Notes

The website is built on the Public4u CMS platform, leveraging jQuery and jQuery UI libraries for interactivity. It integrates mapping functionality via the Mapy.cz API and uses Smartlook for user analytics. The site is mobile-optimized and includes accessibility features such as a voice assistant. Performance is moderate, with multiple external scripts and images. The HTML structure is valid and SEO-friendly with proper meta tags. However, the site lacks modern security headers and detailed technical documentation. Hosting provider details are not explicitly identified. There is an opportunity to modernize the tech stack by adopting newer JavaScript frameworks and improving performance optimization.
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.
