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

Město Mariánské Lázně operates an official municipal website serving residents and visitors of the city Mariánské Lázně in the Czech Republic. The site provides comprehensive information about city governance, public services, cultural events, social programs, and contact details. It is positioned as a government entity portal with a medium-sized audience focused on local community engagement and information dissemination. Technically, the website uses a custom CMS with modern JavaScript libraries such as jQuery, Bootstrap, and Swiper.js, ensuring a responsive and user-friendly experience. The site is mobile optimized and features a clear navigation structure. Security-wise, the website enforces HTTPS and implements a cookie consent mechanism, but lacks visible security headers and a published privacy policy, which are areas for improvement. The absence of WHOIS data reduces domain trustworthiness, though the official branding and content quality support legitimacy. Overall, the website is functional, professional, and safe for general audiences, but could enhance its compliance and security posture.

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

  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

      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 website reflects a government-operated municipal portal focused on providing essential services and information to the public. Its business model is non-commercial, centered on public administration and community service. The site supports transparency through document publication, event calendars, and contact information. The presence of social media links indicates an effort to engage citizens via multiple channels. The lack of WHOIS data and privacy policy suggests potential gaps in administrative transparency and compliance. The portal does not appear to monetize or advertise, aligning with typical government digital service models. Growth indicators include active content updates and integration of mobile-friendly features. Partnerships are limited to related municipal or tourism domains.

Security posture

The website demonstrates a basic security posture with HTTPS enabled and cookie consent implemented, indicating awareness of privacy regulations. However, the absence of key security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options weakens defense against common web attacks. No vulnerability disclosure or incident response information is provided, limiting transparency in security management. The site does not expose sensitive data or use outdated libraries, which is positive. To improve, the organization should publish a privacy policy, implement security headers, and provide clear security contact channels. These steps would enhance compliance with GDPR and NIS2 directives and improve user trust.

Recommendations

  1. Publish a comprehensive privacy policy detailing data processing and user rights to ensure GDPR compliance.
  2. Implement standard security headers (CSP, X-Frame-Options, X-Content-Type-Options) to mitigate common web vulnerabilities.
  3. Establish and publicize an incident response process and security contact information to improve transparency and readiness.
  4. Add a vulnerability disclosure policy or security.txt file to encourage responsible reporting of security issues.
  5. Conduct regular security audits and update third-party libraries to maintain a secure and modern technology stack.

Technical notes

Notes

The website is built on a custom CMS platform with versioning visible in asset URLs, indicating active maintenance. It uses popular JavaScript libraries including jQuery, Bootstrap 4.4.1, Swiper.js for sliders, and mmenu.js for mobile menus, providing a modern and responsive user interface. The site loads external resources from trusted CDNs such as Cloudflare and StackPath. Performance is moderate, with room for optimization in asset loading and caching. Accessibility features are basic, with some ARIA roles and screen reader text present, but could be enhanced for compliance. SEO is supported by meta tags and structured navigation. Hosting provider details are not disclosed. Overall, the technical infrastructure supports a stable and user-friendly experience but could benefit from modernization and enhanced security configurations.
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.
