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 stakeholders interested in municipal services and local governance. It functions primarily as a government portal offering electronic services, news updates, and contact channels for citizen engagement. Technically, the website employs a custom CMS platform (vismo®), integrates Google Analytics with privacy-conscious default settings, and supports multilingual content via Google Translate. The site is secured with HTTPS and includes accessibility features such as dark mode and keyboard navigation support. Performance is moderate with embedded multimedia content and external scripts for analytics and translation. From a security perspective, the site demonstrates good practices including HTTPS enforcement and cookie consent mechanisms. However, some standard security headers like Content-Security-Policy and X-Frame-Options are not explicitly detected, representing an area for improvement. No vulnerabilities or exposed sensitive data were found in the HTML content. The absence of WHOIS data limits domain registration transparency but is likely due to registry policies rather than malicious intent. Overall, the website is a trustworthy and professional municipal portal with good content quality and user experience. Strategic recommendations include enhancing security headers, maintaining privacy compliance, and improving transparency around security policies and incident response procedures.

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

10 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. 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"

    • 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';…

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 website as a key communication and service platform for its citizens and visitors. The site positions itself as an authoritative source for municipal information, public administration, and cultural engagement. Its business model is non-commercial, focused on public service delivery and transparency. The presence of detailed contact information, social media integration, and electronic services indicates a mature digital strategy aimed at improving citizen interaction and operational efficiency. The website supports multiple languages, reflecting an inclusive approach to diverse audiences including tourists and foreign residents. The lack of WHOIS data is a minor limitation but does not detract from the site's credibility given its official branding and content. The site’s ecosystem includes partnerships with local police, social services, and cultural institutions, enhancing its role as a community hub.

Security posture

The website maintains a solid security posture with HTTPS enabled and cookie consent mechanisms in place, aligning with GDPR requirements. The use of Google Analytics is configured to deny consent by default, indicating privacy awareness. However, the absence of explicit security headers such as Content-Security-Policy and X-Frame-Options suggests room for strengthening defenses against common web attacks like clickjacking and cross-site scripting. No incident response or security policy pages were found, which could be improved to enhance transparency and preparedness. The site does not expose sensitive data or use vulnerable libraries in the visible HTML. Overall, the security maturity is good for a government portal but could benefit from implementing additional HTTP security headers and publishing security policies.

Recommendations

  1. Implement Content-Security-Policy and X-Frame-Options HTTP headers to enhance protection against XSS and clickjacking.
  2. Publish a clear security policy and incident response contact information on the website.
  3. Regularly audit third-party scripts and dependencies for vulnerabilities.
  4. Maintain and update cookie consent mechanisms to ensure ongoing GDPR compliance.
  5. Enhance WHOIS transparency if possible or provide domain registration information on the site for trust.

Technical notes

Notes

The website uses a proprietary CMS platform (vismo®) with a combination of HTML5, CSS3, and JavaScript. It integrates Google Analytics and Google Translate for analytics and multilingual support. The site includes embedded YouTube videos and social media links. Performance is moderate with some external dependencies. Accessibility features such as keyboard navigation and dark mode toggle are implemented, improving user experience. SEO is supported by meta tags and structured navigation. The site lacks some modern security headers but otherwise follows good web standards. Hosting provider details are not explicitly found. The site is mobile optimized and responsive. Opportunities exist to modernize security headers and improve WHOIS transparency.
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.
