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

The website muas.cz serves as the official municipal portal for the city of Aš in the Czech Republic. It provides residents and visitors with access to city news, public services, contact information, and various online tools such as forms and event calendars. The site is positioned as a trusted government resource with a clear focus on local governance and community engagement. The target audience primarily includes local citizens and stakeholders interested in municipal affairs. Technically, the website is built on the vismoWeb5 CMS platform, utilizing standard web technologies including HTML5, CSS3, and JavaScript. It incorporates accessibility features and mobile optimization, along with multilingual support via Google Translate. The site demonstrates moderate performance and good SEO practices, although some improvements could be made in security header implementation. From a security perspective, the site enforces HTTPS and avoids exposing sensitive data. However, it lacks explicit security policies and incident response information, and does not implement a cookie consent mechanism despite having a cookie policy. No vulnerabilities or malicious content were detected. Overall, the security posture is solid but could benefit from enhanced transparency and technical controls. The domain registration aligns well with the municipal identity, showing consistency and legitimacy. The site links to several trusted partner domains related to local government and services. There are no signs of blocking or WAF interference, and the content is safe for general audiences. Strategic recommendations include adding security and incident response policies, implementing cookie consent, and enhancing security headers to improve compliance and trust.

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

12 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

      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

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

Městský úřad Aš operates as a small-sized government entity providing essential municipal services through its official website. The business model is focused on public service delivery and community information dissemination. The site’s market position is that of an authoritative local government portal, serving residents and local businesses. Revenue streams are not applicable as it is a public institution. The target customer segments include local citizens, businesses, and visitors seeking municipal information or services. Growth indicators include active content updates and integration of online services. The partnership ecosystem includes local government bodies, police, health services, and community organizations. Strategic observations highlight a well-maintained digital presence with room for enhanced security and privacy compliance.

Security posture

The security maturity of muas.cz is moderate to good. The site uses HTTPS exclusively, ensuring encrypted communications. No critical vulnerabilities or exposed sensitive data were found in the HTML content. However, the absence of security headers such as Content-Security-Policy and Strict-Transport-Security reduces defense-in-depth. The lack of a published security policy or incident response plan limits transparency and preparedness. GDPR compliance is partially addressed through privacy and cookie policies, but no active consent mechanism is implemented. The site’s security culture appears functional but could be improved by formalizing policies and technical controls. No signs of malware, phishing, or suspicious activity were detected.

Recommendations

  1. Implement and publish a comprehensive security policy and incident response plan accessible from the website.
  2. Add a cookie consent mechanism to comply fully with GDPR requirements.
  3. Deploy security headers including Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security to enhance protection.
  4. Regularly audit and update third-party scripts and libraries to avoid vulnerabilities.
  5. Enhance transparency by providing a dedicated data protection officer contact and detailed privacy compliance information.

Technical notes

Notes

The website is built on the vismoWeb5 CMS platform, leveraging standard web technologies such as HTML5, CSS3, and JavaScript. It integrates Google Translate for multilingual support and uses custom scripts for UI enhancements like smooth scrolling and menu toggling. The site is mobile optimized and accessible, with semantic roles and ARIA attributes implemented. Performance is moderate, with no major blocking scripts detected. The hosting provider is not explicitly identified. There is some technical debt in the form of missing security headers and lack of cookie consent mechanisms. Opportunities exist to modernize security practices and improve compliance-related features without major infrastructure changes.
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.
