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

Mladá Boleslav's official website reflects a medium-sized municipal government entity focused on delivering public services digitally. Its business model is non-commercial, aimed at transparency, citizen engagement, and service facilitation. The site leverages partnerships with technology providers such as WEBHOUSE and vismo CMS. The presence of event calendars, news, and citizen portals indicates active community engagement. The lack of commercial advertising and affiliate programs aligns with its government sector nature. The site’s consistent branding and trust signals such as official logos and contact details reinforce its authoritative position in the local market.

Security posture

The website maintains a good security posture with HTTPS encryption, integration of Google reCAPTCHA for form protection, and a cookie consent mechanism that respects user privacy choices. No critical vulnerabilities or exposed sensitive data were detected in the HTML content. However, the absence of a dedicated security policy page and incident response contact information limits transparency in security governance. Security headers were not explicitly detected, suggesting an opportunity to enhance HTTP response security. Overall, the site is secure for its purpose but could benefit from formalizing and publishing security policies and incident response procedures.

Recommendations

  1. Publish a dedicated security policy page outlining security practices and user guidance.
  2. Provide clear incident response contact channels such as security@ or abuse@ email addresses.
  3. Implement and enforce security HTTP headers like Content-Security-Policy and X-Frame-Options.
  4. Regularly review and update third-party scripts to mitigate potential vulnerabilities.
  5. Enhance transparency by adding terms of service and data retention policy documents.

Technical notes

Notes

The website is built on a stable CMS platform (vismo) with a modern tech stack including HTML5, CSS3, and JavaScript. It uses Google Fonts for typography and integrates Google Analytics with consent management, reflecting good digital maturity. Performance is moderate with asynchronous script loading and image blending effects. Mobile optimization and accessibility features are well implemented, including skip links and keyboard focus management. The site uses Google reCAPTCHA v2 and v3 to protect forms from abuse. No major technical debt or deprecated technologies were observed. Opportunities exist to improve security headers and optimize performance further.
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.
