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

The website www.ctyrkoly.cz serves as the official online presence for the municipality of Čtyřkoly in the Czech Republic. It provides residents and visitors with timely information about local news, events, municipal office activities, waste collection schedules, and community services. The site targets local citizens and stakeholders interested in municipal governance and community engagement. The business model is typical for a government entity, focusing on information dissemination and public service rather than commercial activities. Technically, the website employs a traditional web stack including jQuery, Bootstrap 4, and Swiper.js for UI components and interactivity. The CMS appears to be a custom or regional solution (GCM CMS). The site is mobile-optimized with responsive design and accessible navigation, though accessibility features are basic. Performance is moderate, with no evident critical technical issues. From a security perspective, HTTPS is used, and a cookie consent banner is implemented, indicating some privacy compliance efforts. However, no explicit privacy policy, terms of service, or security incident response information is found. WHOIS data for the domain is unavailable, which limits the ability to fully verify domain legitimacy and trustworthiness. No security headers or advanced security practices are evident in the provided data. Overall, the website is a functional and professional municipal portal with good content quality and user experience. The main risks relate to incomplete privacy and security disclosures and the lack of domain registration transparency. Strategic improvements in these areas 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

7 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

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.

Business context

Business profile

The municipality of Čtyřkoly operates this website as a key communication channel with its residents and visitors. The site positions itself as a reliable source for local governance information, community events, and public services. It leverages partnerships with regional payment portals and local community sites to extend service offerings. The business model is non-commercial, focusing on public administration and community engagement. The target audience includes local residents, municipal employees, and visitors interested in the area. The site shows consistent branding and regular content updates, indicating active management. Growth indicators include integration with mobile apps and digital payment solutions, reflecting a moderate level of digital maturity.

Security posture

The website demonstrates a basic security posture with HTTPS enabled and a cookie consent mechanism in place. However, the absence of a privacy policy, terms of service, and security incident response information indicates gaps in compliance and transparency. No advanced security headers or vulnerability disclosures are present. The lack of WHOIS data raises concerns about domain registration transparency, although the site content and contact information appear legitimate. There is no evidence of exposed sensitive data or vulnerable libraries in the provided content. Overall, the security maturity is moderate but could be improved by implementing comprehensive privacy and security policies, publishing incident response contacts, and enhancing technical security controls.

Recommendations

  1. Publish a comprehensive privacy policy and terms of service to improve legal compliance and user trust.
  2. Implement and configure security headers such as Content Security Policy (CSP), HSTS, X-Frame-Options, and X-Content-Type-Options.
  3. Establish and publicize a security incident response and vulnerability disclosure policy to enhance transparency and readiness.
  4. Investigate and resolve the missing WHOIS data issue to ensure domain registration transparency and trustworthiness.
  5. Enhance accessibility features to meet recognized standards and improve user experience for all visitors.

Technical notes

Notes

The website uses a combination of jQuery, Bootstrap 4, Swiper.js, and other JavaScript libraries to deliver a responsive and interactive user experience. The CMS appears to be a custom or regional solution, which may limit integration with modern tools but suits the municipal use case. Performance is moderate with no critical errors detected. The site includes a cookie consent banner indicating awareness of privacy regulations. However, the absence of analytics scripts suggests minimal user tracking, which aligns with privacy best practices. The technical stack is stable but could benefit from modernization and enhanced security configurations.
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.
