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

Městské muzeum Horažďovice is a municipal cultural institution providing exhibitions, events, and visitor services focused on the local history and culture of Horažďovice, Czech Republic. The website serves as an information portal for visitors, featuring event calendars, exhibition details, and contact information. The museum is affiliated with the local municipality, enhancing its credibility and community role. Technically, the website uses a traditional tech stack including jQuery, jQuery UI, and Unite Gallery, with Google Tag Manager for analytics and marketing. The site is mobile optimized and offers a cookie consent mechanism, indicating some level of privacy compliance. Security posture is moderate with no visible critical vulnerabilities but lacks advanced security headers and explicit security policies. WHOIS data is missing, which reduces domain trustworthiness from a registration perspective but does not necessarily indicate malicious intent given the municipal nature of the site. Overall, the website is functional, informative, 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

  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 museum operates as a small government/non-profit entity serving local and tourist audiences interested in cultural heritage. Its business model revolves around public cultural services, exhibitions, and event hosting. The website supports this by providing detailed event calendars, exhibition information, and visitor guidance. The presence of social media links and integration with local tourism sites like Kudyznudy.cz suggests active community engagement and partnership. The lack of WHOIS data is unusual but may be due to privacy or registry issues. The museum's market position is local and community-focused, with no commercial revenue streams evident from the website. The site’s content and structure support its mission effectively, though modernization and enhanced security practices could improve its digital maturity.

Security posture

The website demonstrates a basic to moderate security posture. It uses HTTPS (implied by external Google Tag Manager scripts loaded over HTTPS), and implements a cookie consent banner with granular options, indicating awareness of privacy regulations. However, no explicit security headers (CSP, HSTS, X-Frame-Options) were detected in the provided data, which are recommended best practices. The JavaScript libraries used are somewhat outdated (jQuery 2.1.4), which could pose risks if not regularly patched. No security.txt or incident response contacts are published, limiting transparency for vulnerability reporting. No exposed sensitive data or obvious vulnerabilities were found in the HTML content. Overall, the site is reasonably secure for a municipal informational site but could benefit from enhanced security controls and policies.

Recommendations

  1. Implement and enforce HTTP security headers such as Content-Security-Policy, Strict-Transport-Security, and X-Frame-Options to mitigate common web attacks.
  2. Verify and ensure the domain WHOIS registration is complete and publicly available to improve trust and legitimacy.
  3. Update JavaScript libraries, especially jQuery, to the latest stable versions to reduce vulnerability risks.
  4. Publish a dedicated privacy policy and security policy page with clear GDPR compliance statements.
  5. Add a security.txt file and provide incident response contact information to facilitate vulnerability reporting and improve security transparency.

Technical notes

Notes

The website uses a traditional front-end stack with jQuery 2.1.4, jQuery UI, and Unite Gallery for image display. Google Tag Manager is used for analytics and marketing, including Facebook Pixel for retargeting. The site is mobile optimized with responsive design elements and uses Font Awesome for icons. No CMS or backend platform was explicitly detected. Performance is moderate, with no major issues visible in the HTML. Accessibility is basic, with some ARIA roles used in cookie consent dialogs. SEO is basic with meta tags for keywords and description but no structured data (JSON-LD) found. The site could benefit from modernization of libraries, improved accessibility, and enhanced SEO practices.
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.
