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

The website tnv.cz serves as the official online portal for the municipal government of Týn nad Vltavou, Czech Republic. It provides comprehensive information and services related to city administration, public notices, cultural events, and citizen resources. The site targets local residents, businesses, and visitors, offering a range of municipal services including contact forms, public procurement details, and tourism information. The domain is well-established since 2002, reflecting a mature digital presence for the city government. Technically, the website employs a traditional HTML/CSS/JavaScript stack with the Vismo CMS platform. It integrates Google services such as reCAPTCHA for form security and Google Translate for multilingual support. The site is hosted under a Czech registrar and uses HTTPS, ensuring secure communications. Performance and mobile optimization are adequate, with good accessibility and SEO practices observed. From a security perspective, the site demonstrates good baseline practices including HTTPS enforcement and anti-bot measures on forms. However, it lacks explicit security headers and formal incident response or vulnerability disclosure policies. Privacy compliance is addressed with GDPR references and cookie policy disclosures, though no active consent mechanism is present. The WHOIS data aligns well with the website content, indicating legitimacy and trustworthiness. Overall, the website is a reliable and professional municipal portal with solid content and technical implementation. Security posture is adequate but could be enhanced with additional headers and formal policies. Privacy compliance is basic but sufficient for the site’s scope. Strategic recommendations include improving security headers, adding incident response contacts, and implementing cookie consent mechanisms to strengthen compliance and trust.

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

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

Týn nad Vltavou’s official website positions itself as a key municipal communication channel, providing transparency and accessibility to local government operations. Its competitive advantage lies in comprehensive local content, integration with official public procurement and contract registries, and active social media engagement. The business model is public service oriented, funded by municipal budgets, focusing on citizen engagement and service delivery. The target customer segments include residents, local businesses, tourists, and municipal employees. Growth indicators include regular content updates and digital service expansions such as online forms and e-services. The partnership ecosystem includes regional government portals, public utilities, and cultural institutions. Strategic observations highlight a stable, community-focused operation with opportunities to modernize security and privacy practices.

Security posture

The website exhibits a moderate security maturity level with HTTPS enabled and Google reCAPTCHA protecting user input forms. No critical vulnerabilities or exposed sensitive data were detected in the HTML content. However, the absence of key HTTP security headers such as Content Security Policy (CSP), HSTS, and X-Frame-Options reduces defense-in-depth. There is no publicly disclosed incident response or vulnerability disclosure policy, which limits transparency and preparedness. GDPR compliance is acknowledged but lacks active cookie consent mechanisms. Overall, the security posture is adequate for a municipal informational site but would benefit from enhancements to headers, formal policies, and ongoing security audits to mitigate risks and improve trust.

Recommendations

  1. Implement HTTP security headers including CSP, HSTS, X-Frame-Options, and X-XSS-Protection to enhance browser security.
  2. Publish a formal incident response and vulnerability disclosure policy with clear contact channels to improve transparency and readiness.
  3. Introduce an explicit cookie consent mechanism to comply fully with GDPR and enhance user privacy control.
  4. Regularly audit and update third-party scripts and dependencies to prevent vulnerabilities.
  5. Enhance security culture by training staff and communicating security best practices to users and administrators.

Technical notes

Notes

The website is built on a stable and mature CMS platform (Vismo) with standard web technologies (HTML5, CSS, JavaScript). It integrates Google services for translation and bot protection, indicating moderate digital maturity. Hosting is provided by a reputable Czech registrar, Active24, ensuring reliable infrastructure. Performance is moderate with room for optimization, especially in loading times and resource management. The site is mobile optimized and accessible, supporting a broad user base. Technical debt appears low, but modernization opportunities exist in adopting modern security headers and improving SEO metadata. Technical risks are minimal but should be managed through regular maintenance and security updates to ensure uninterrupted municipal services.
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.
