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

Městské muzeum v Čelákovicích is a small, local municipal museum established in 1903, serving the Prague-East district in the Czech Republic. The museum offers cultural and historical exhibitions, public events, and services such as a tourist information center and venue rentals. The website reflects a professional and consistent brand presence with clear contact information and multilingual support. Technically, the site uses the Public4u CMS platform with jQuery and related libraries, providing moderate performance and good mobile optimization. Security posture is adequate with HTTPS enabled but lacks advanced security headers and explicit security policies. The absence of WHOIS data limits domain registration trust analysis, but the website content and contact details support legitimacy. Overall, the site is well-maintained and trustworthy for its intended audience.

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

    • 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
      • 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 museum operates as a non-profit cultural institution focused on local history and education. Its market position is stable within the local community, leveraging long-standing heritage since 1903. Key services include exhibitions, public cultural events, and archaeological consulting for builders. The website supports multiple languages, indicating outreach beyond local visitors. The absence of commercial advertising or tracking suggests a focus on public service rather than revenue generation. Partnerships appear limited to local or regional entities, with no evidence of subsidiaries or parent companies. The museum's digital presence is professional but could benefit from enhanced security and privacy transparency to align with modern compliance standards.

Security posture

The website demonstrates a basic to moderate security maturity level. HTTPS is enforced, and forms use POST methods, reducing exposure to common web vulnerabilities. However, no advanced security headers such as Content-Security-Policy or X-Frame-Options were detected, which could mitigate risks like XSS or clickjacking. No vulnerability disclosures, incident response contacts, or security policies are published, indicating potential gaps in security governance and transparency. The use of legacy JavaScript libraries warrants regular updates to prevent exploitation. Overall, the security posture is sufficient for a low-risk cultural site but should be enhanced to protect user data and maintain trust.

Recommendations

  1. Implement comprehensive security headers including Content-Security-Policy, X-Content-Type-Options, and X-Frame-Options.
  2. Publish clear privacy, security, and incident response policies on the website.
  3. Regularly update all JavaScript libraries and CMS components to latest secure versions.
  4. Add a vulnerability disclosure policy or security.txt file to facilitate responsible reporting.
  5. Enhance accessibility and GDPR compliance indicators, including cookie consent transparency.

Technical notes

Notes

The website is built on the Public4u CMS platform using jQuery and jQuery UI libraries, with additional scripts for gallery and mobile menu functionality. The site is mobile-optimized with responsive design and basic accessibility features. Performance is moderate, with no major issues detected in the HTML structure or SEO metadata. However, the technology stack includes some legacy components that may require modernization. Hosting provider details are not disclosed. The site lacks advanced security headers and analytics tools, indicating a minimalistic technical footprint focused on content delivery rather than marketing or tracking.
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.
