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

Národní muzeum is the Czech Republic's national museum institution, providing a wide range of cultural, educational, and exhibition services to the public. The website offers comprehensive information about museum objects, exhibitions, events, and online content such as podcasts and virtual tours. It targets a broad audience including families, schools, researchers, and tourists. The institution is positioned as a leading government cultural entity with strong partnerships and a modern digital presence. Technically, the website employs a mix of established technologies including jQuery, Google Tag Manager, and Facebook Pixel, with good mobile optimization and accessibility features. The site uses HTTPS and implements a detailed cookie consent mechanism, reflecting a commitment to privacy compliance. However, some security headers are missing, and no explicit incident response or vulnerability disclosure information is provided. From a security perspective, the site demonstrates good practices such as encrypted connections and privacy controls but could improve by publishing security policies and enhancing HTTP security headers. The absence of WHOIS data limits domain registration trust assessment, though the website content and external references strongly indicate legitimacy. Overall, the site is professional, content-rich, and user-friendly, with moderate to strong security and privacy postures. Strategic improvements in security transparency and domain registration visibility would further enhance trust and compliance.

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

    • High

      Third-party services without privacy policy

      Detected services: Google Analytics, Facebook, Twitter, Google APIs

      What to do: Document all third-party data sharing in your privacy policy

  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 Content-Security-Policy header

      Controls resources the browser is allowed to load

      What to do: Implement a Content-Security-Policy appropriate for your application

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

Národní muzeum operates as a government-funded cultural institution with a large footprint in the Czech Republic's museum and heritage sector. Its competitive advantage lies in its extensive collection, diverse programming, and integration of modern digital experiences such as virtual reality and mobile apps. Revenue streams likely include government funding, ticket sales, and partnerships. The target customer segments span general public visitors, educational institutions, and cultural tourists. The museum maintains a robust partnership ecosystem with media, cultural, and commercial entities, enhancing its outreach and funding opportunities. The website reflects a mature digital strategy supporting engagement and service delivery.

Security posture

The website's security maturity is moderate to good. HTTPS is enforced, and cookie consent is managed with user choice, indicating GDPR awareness. However, the lack of visible security headers such as Content-Security-Policy and absence of published incident response or vulnerability disclosure policies represent gaps. No exposed sensitive data or vulnerable libraries were detected in the HTML content. The site would benefit from publishing a security.txt file and providing explicit security contact channels to improve incident response readiness and transparency. Overall, the security posture supports business continuity but has room for enhancement to meet best practices fully.

Recommendations

  1. Implement and configure HTTP security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to mitigate common web attacks.
  2. Publish a security.txt file at the root domain to facilitate vulnerability reporting and improve transparency.
  3. Provide explicit incident response contact information, such as a dedicated security or abuse email address, on the website.
  4. Enhance WHOIS domain registration visibility or verify domain registration details to improve trust and legitimacy assessment.
  5. Regularly audit third-party scripts and tracking technologies to ensure no vulnerable or deprecated libraries are in use.

Technical notes

Notes

The website uses a combination of legacy and modern web technologies, including jQuery 2.2.4, Google Tag Manager, Facebook Pixel, and Select2 for enhanced UI elements. The site is mobile-optimized with responsive design and accessibility considerations. Performance is moderate, with potential improvements in loading speed by optimizing assets and scripts. The absence of a detected CMS suggests a custom or proprietary platform. Hosting details are not explicit but likely stable given the site's scale. Technical debt appears low, but updating jQuery to a more recent version could improve security and performance. SEO is well addressed with proper meta tags and structured navigation.
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.
