Město Sedlčany operates as the official municipal government website for the city of Sedlčany in the Czech Republic, providing residents and visitors with news, event information, public notices, and contact resources. The site targets local citizens and tourists, offering multilingual support and a range of municipal services. The business model is centered on public service and community engagement, positioning itself as a trusted local government authority. Technically, the website is built on the Public4u CMS platform, utilizing common web technologies such as jQuery and JavaScript. The site is moderately optimized for performance and mobile use, with basic accessibility features and good SEO practices. Security-wise, the site enforces HTTPS and includes cookie consent mechanisms, but lacks visible advanced security headers and explicit security policies.

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

    • 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

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 website serves as a digital front for the municipal government of Sedlčany, focusing on delivering timely information and services to its community. Its competitive advantage lies in its official status and comprehensive local content, including event calendars, public announcements, and contact channels. Revenue streams are typical for government entities, primarily funded by public budgets rather than commercial activities. The target customer segments include local residents, businesses, and tourists. Growth indicators are not explicit but the site’s multilingual support and integration with social media suggest efforts to broaden reach and engagement. The partnership ecosystem includes regional associations and municipal communication platforms, enhancing service delivery and community interaction. Strategic observations highlight the need for improved security posture and transparency to maintain trust and compliance with evolving regulations.

Security posture

The website demonstrates a foundational security posture with HTTPS enforcement and cookie consent mechanisms, indicating awareness of privacy and data protection requirements. However, the lack of visible security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options suggests potential vulnerabilities to common web attacks like XSS and clickjacking. No explicit incident response or security policy information is provided, limiting transparency and preparedness signals. The use of third-party analytics (Smartlook) introduces moderate user tracking, which is managed with basic privacy compliance. The absence of WHOIS data reduces domain trustworthiness slightly but does not directly impact site security. Overall, the security maturity is moderate, with recommendations to enhance header configurations, update libraries, and publish security policies to strengthen defenses and compliance.

Recommendations

  1. Implement comprehensive HTTP security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to mitigate common web vulnerabilities.
  2. Publish explicit security and incident response policies on the website to improve transparency and preparedness.
  3. Regularly update all JavaScript libraries and dependencies to patch known vulnerabilities.
  4. Enhance mobile optimization and accessibility features to improve user experience across devices and for users with disabilities.
  5. Investigate and resolve WHOIS data unavailability to improve domain registration transparency and trust.

Technical notes

Notes

The website is built on the Public4u CMS platform, leveraging standard web technologies such as jQuery and JavaScript for interactivity and UI components. CSS is used for styling with separate stylesheets for screen and print media. The site includes multiple JavaScript files for gallery, AJAX loading, popups, and UI enhancements. Performance is moderate with no explicit indicators of slow loading but could benefit from optimization. Mobile responsiveness is basic, with viewport meta tags present but no advanced responsive frameworks detected. Accessibility is basic, with skip links and language attributes but no ARIA landmarks or advanced accessibility features. SEO is supported by meta keywords, descriptions, and structured navigation. Hosting provider details are not discernible from the content. Overall, the technical infrastructure is functional but could be modernized and optimized for better performance and accessibility.
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.
