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

The website www.jh.cz serves as the official online presence for the city of Jindřichův Hradec, providing comprehensive information about municipal services, cultural events, administrative contacts, and local news. It targets residents, visitors, and stakeholders interested in the city's governance and community activities. The site is positioned as a trusted source for official city information and public service announcements. Technically, the website employs a Czech CMS platform called Public4u, utilizes common JavaScript libraries such as jQuery and jQuery UI, and integrates Google Analytics for visitor tracking. The site is secured with HTTPS and includes cookie consent mechanisms, reflecting a moderate level of digital maturity. Mobile optimization and accessibility are adequate but could be improved. From a security perspective, the site benefits from HTTPS encryption and cookie consent but lacks visible advanced security headers and published security policies. The absence of WHOIS data for the domain is a notable anomaly that slightly reduces trustworthiness, though the official contact information and consistent branding mitigate concerns. No vulnerabilities or exposed sensitive data were detected in the provided content. Overall, the website presents a professional and trustworthy interface for municipal communication but would benefit from enhanced transparency in security policies, improved accessibility, and resolution of WHOIS data visibility to strengthen its security posture and compliance standing.

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

      What to do: Implement a cookie consent banner that appears on first visit

  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 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 Jindřichův Hradec operates this website as a key communication channel for local government services and community engagement. The site supports transparency and citizen participation through features like participatory budgeting, official documents, and event calendars. Its competitive advantage lies in its official status and comprehensive local content tailored to residents and tourists. Revenue streams are typical for government entities, primarily funded by public budgets rather than commercial activities. The partnership ecosystem includes cultural institutions and local service providers linked via subdomains and external sites. Growth indicators include active event promotion and digital service offerings such as online reservations and mobile apps. Strategic observations suggest opportunities to enhance digital services and security transparency to better serve constituents and comply with evolving regulatory requirements.

Security posture

The website demonstrates a baseline security maturity with HTTPS enforcement and cookie consent mechanisms in place. However, it lacks published security policies, incident response contacts, and vulnerability disclosure programs, which are critical for comprehensive security governance. The absence of security headers such as Content-Security-Policy or X-Frame-Options indicates potential areas for hardening against common web threats. No exposed sensitive data or vulnerable libraries were identified, suggesting a stable environment. Compliance with GDPR is implied through cookie consent and privacy policy presence but could be improved with explicit data protection officer contact and detailed data retention policies. Incident response readiness and security culture indicators are not evident from the content, highlighting areas for organizational improvement.

Recommendations

  1. Publish a formal security policy and incident response plan accessible on the website.
  2. Implement and expose a vulnerability disclosure or security.txt file to encourage responsible reporting.
  3. Enhance HTTP security headers to mitigate common web vulnerabilities.
  4. Improve accessibility features to meet higher standards and broaden user inclusivity.
  5. Resolve WHOIS data visibility issues to increase domain trust and legitimacy.

Technical notes

Notes

The website is built on the Public4u CMS platform, a Czech content management system, and leverages standard JavaScript libraries including jQuery and jQuery UI. Google Analytics is used for traffic monitoring. The site is served over HTTPS, indicating good SSL configuration. Performance is moderate with room for optimization, particularly in mobile responsiveness and accessibility. The meta tags and SEO elements are well implemented, supporting good search engine visibility. Technical debt appears low, but modernization opportunities exist in adopting stronger security headers and improving accessibility compliance. Hosting provider details are not explicitly identified, which could be clarified for operational 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.
