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

Cheb.cz serves as a critical digital interface between the city government and its citizens, offering a broad range of municipal services online. Its market position is that of an essential government portal, with no commercial business model but a public service mandate. The site supports transparency through publication of official notices, event information, and online forms for citizen interaction. The presence of multiple social media channels and integration with geographic information systems indicates a commitment to modern communication and service delivery. The domain's long history since 1998 supports its credibility and stability. The website's ecosystem includes partner domains related to municipal services and geographic data, enhancing its service scope. The business intelligence suggests a well-managed municipal digital strategy focused on accessibility, transparency, and citizen engagement.

Security posture

The security posture of cheb.cz is robust for a municipal website. HTTPS is enforced, and Google reCAPTCHA is implemented on forms to mitigate automated abuse. Cookie consent mechanisms comply with GDPR, enhancing privacy protections. No exposed sensitive data or vulnerable libraries were detected in the HTML content. However, explicit security headers such as Content-Security-Policy and X-Frame-Options are not visibly configured, representing an area for improvement. There is no published security policy or incident response contact, which could enhance transparency and readiness. The absence of a security.txt file limits vulnerability disclosure options. Overall, the site follows good security practices but could benefit from additional hardening and formal security documentation.

Recommendations

  1. Implement and enforce security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to enhance protection against common web attacks.
  2. Publish a formal security policy and provide dedicated incident response contact channels to improve transparency and readiness.
  3. Add a security.txt file to facilitate responsible vulnerability disclosure and improve security collaboration.
  4. Regularly audit and update third-party scripts and libraries to mitigate potential vulnerabilities.
  5. Enhance monitoring and logging capabilities to detect and respond to suspicious activities promptly.

Technical notes

Notes

The website is built on a specialized municipal CMS platform (Vismo) and uses standard web technologies including HTML5, CSS, and JavaScript. It integrates Google services such as Analytics, Tag Manager, Translate, and reCAPTCHA, indicating a modern and functional tech stack. Hosting is consistent with Czech providers, and domain registration is longstanding and stable. The site is mobile-optimized and accessible, with clear navigation and structured content. Performance is moderate, with potential for optimization. The use of multiple external scripts and services is well-managed with consent mechanisms. Technical risks are low, but the absence of some security headers and formal security documentation represents technical debt that should be addressed to maintain resilience.
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.
