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

The website www.zdarns.cz serves as the official municipal portal for the city of Žďár nad Sázavou in the Czech Republic. It provides comprehensive information and services for citizens, local businesses, and visitors, including city news, administrative contacts, tourism guides, cultural events, and online public services. The site is well-structured with clear navigation tailored to different user groups such as citizens, entrepreneurs, and visitors. The business model is that of a government service portal aimed at transparency and community engagement. Technically, the website employs modern web technologies including HTML5, CSS3, JavaScript, jQuery, and Bootstrap for responsive design. It integrates Google Fonts and Google Analytics for typography and traffic analysis respectively. The site is served over HTTPS, ensuring encrypted communication. The cookie consent mechanism is implemented inline, allowing users to manage cookie preferences, which indicates a basic level of privacy compliance. From a security perspective, the site enforces HTTPS and uses cookie consent banners but lacks visible security headers such as Content-Security-Policy or X-Frame-Options. No security.txt or explicit incident response contacts are found. The WHOIS data for the domain is unavailable, which slightly reduces trust from a domain registration standpoint, but the presence of official contact information and consistent branding supports legitimacy. Overall, the website is professional, trustworthy, and serves its purpose effectively. Recommendations include publishing a privacy policy and terms of service, implementing security headers, and improving transparency around data protection and incident response to enhance security posture 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

  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 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

      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

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 municipal website positions itself as the authoritative source for city-related information and services, targeting residents, businesses, and tourists. Its competitive advantage lies in comprehensive content coverage, official endorsements, and integration with partner cultural and tourism sites. Revenue streams are typical for government entities, primarily funded by public budgets. The partnership ecosystem includes local cultural institutions, tourism portals, and service providers for payments and infrastructure projects. Growth indicators include active event promotion and digital service expansion. The website reflects a mature digital presence aligned with public sector standards.

Security posture

The security maturity level is moderate. HTTPS is enforced, and cookie consent is implemented, indicating awareness of privacy and security requirements. However, the absence of key security headers and lack of published security policies or incident response contacts highlight gaps. No vulnerabilities or exposed sensitive data were detected in the HTML content. Compliance with GDPR is partial, as no privacy policy is found. The site would benefit from enhanced security controls, regular audits of third-party scripts, and transparent data protection disclosures to improve trust and resilience.

Recommendations

  1. Publish a comprehensive privacy policy and terms of service accessible from the homepage.
  2. Implement HTTP security headers including Content-Security-Policy, X-Frame-Options, X-Content-Type-Options, and Strict-Transport-Security.
  3. Establish and publish an incident response policy and contact channel for security issues.
  4. Conduct regular security audits of third-party scripts and update libraries to mitigate vulnerabilities.
  5. Enhance accessibility features and provide clear data retention and user data handling disclosures.

Technical notes

Notes

The website uses a modern tech stack with HTML5, CSS3, JavaScript, jQuery, and Bootstrap for responsive design. Google Fonts and Google Analytics are integrated for typography and analytics. The site loads moderately fast with good mobile optimization. No CMS is explicitly detected, suggesting a custom or proprietary content management system. The site lacks advanced accessibility features but provides basic support. SEO is well addressed with meta tags and structured navigation. Technical risks include reliance on third-party scripts and missing security headers which could be exploited if not managed properly.
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.
