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

The website www.znojmocity.cz serves as the official online presence of the city of Znojmo, Czech Republic. It provides comprehensive information about the city administration, cultural events, tourism, social services, and public notices. The site targets residents, visitors, and local businesses, offering a broad range of municipal services and news updates. The business model is that of a government entity focused on public service and information dissemination. The site maintains a consistent brand identity aligned with official city symbols and includes active social media channels to engage the community. Technically, the website is built on a proprietary CMS platform (vismo) and leverages modern web technologies including HTML5, CSS3, JavaScript, and integrates Google Analytics and Google Translate for accessibility and analytics. The site is mobile optimized and includes accessibility features, providing a good user experience. Performance is moderate, with embedded multimedia content and external scripts. From a security perspective, the site enforces HTTPS and implements cookie consent mechanisms compliant with GDPR. However, no explicit security policy or incident response contact information is published, and security headers are not visibly configured. No vulnerabilities or exposed sensitive data were detected in the content. The absence of WHOIS data limits domain legitimacy verification, but the official nature of the content and branding strongly support its authenticity. Overall, the website is a well-maintained municipal portal with good content quality, technical implementation, and privacy compliance. Strategic improvements include publishing a security policy, adding security headers, and providing incident response contacts to enhance trust and security posture.

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

13 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

  2. Email security

    SPF, DKIM and DMARC stop others sending email that looks like it comes from your domain, a common route to phishing and invoice fraud.

    • Critical

      No email authentication configured

      Domain is vulnerable to email spoofing

      What to do: Implement SPF, DKIM, and DMARC immediately

  3. DNS health

    DNS sends visitors and email to the right servers. Misconfigured records can cause outages or let someone redirect your traffic.

    • Critical

      DNS Resolution Failed

      Unable to resolve domain A records

      What to do: Verify domain is properly configured and not expired

  4. 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"

      • CWE-319
      • OWASP A04:2025
      • ASVS V3.4.1
    • High

      Missing X-Frame-Options header

      Prevents clickjacking attacks

      What to do: Add "X-Frame-Options: DENY" or "X-Frame-Options: SAMEORIGIN"

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 city of Znojmo operates this official website to serve its residents and visitors by providing essential municipal information and services. The site positions itself as the authoritative source for local governance, cultural activities, social programs, and administrative procedures. Its competitive advantage lies in comprehensive content coverage, official endorsements, and integration with local digital services such as mobile alerts and online sign language interpretation. Revenue streams are typical for government entities, primarily funded through public budgets. The target customer segments include local citizens, tourists, and businesses requiring municipal services. Growth indicators include active content updates, social media engagement, and digital service expansion. The partnership ecosystem includes local authorities, social service providers, and technology vendors supporting the CMS and analytics infrastructure.

Security posture

The website demonstrates a moderate security maturity level with HTTPS enforcement and GDPR-compliant cookie consent mechanisms. The absence of visible security headers such as Content-Security-Policy or X-Frame-Options suggests room for improvement in mitigating common web threats. No security.txt or vulnerability disclosure policy is present, limiting transparency for security researchers. The site does not expose sensitive data or use vulnerable libraries based on the analysis. Incident response readiness is unclear due to lack of published contacts. Overall, the security posture is adequate for a government informational site but would benefit from enhanced security policies and technical controls.

Recommendations

  1. Publish a clear security policy and incident response contact information on the website.
  2. Implement standard security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  3. Add a security.txt file to facilitate responsible vulnerability disclosure.
  4. Regularly audit and update third-party scripts and libraries to prevent vulnerabilities.
  5. Enhance transparency and trust by providing detailed privacy and data protection information.

Technical notes

Notes

The website is built on a proprietary CMS platform (vismo) with a technology stack including HTML5, CSS3, JavaScript, and integration of Google services such as Analytics and Translate. The site uses embedded YouTube videos and external scripts for functionality and tracking. Performance is moderate, with some potential optimization opportunities in script loading and multimedia handling. The site is mobile optimized and includes accessibility features such as skip links and ARIA roles. Technical debt appears low, but the lack of modern security headers and incident response mechanisms indicates areas for modernization. Hosting provider details are not explicitly identified. Overall, the technical infrastructure supports the business needs effectively but could be enhanced with improved security and performance tuning.
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.
