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

3 findings rated critical or high. Fix these first.

  1. 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

      • 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';…

  2. GDPR outside view

    These are the privacy signals visitors and data protection authorities look for under GDPR.

    • 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

  3. Network security

    Services reachable from the internet are the first thing attackers probe. Anything open that does not need to be should be closed.

    • High

      High-Risk Service Exposed: FTP

      Port 21 (FTP) is publicly accessible - FTP - Often unencrypted file transfer

      What to do: Consider restricting access to FTP or implementing strong authentication

      • NIS2 21(2)(e)
      • IR 2024/2690 6.7.2(f): Implementing Regulation (EU) 2024/2690, Annex point 6.7.2(f): Network security

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 holds a strong position as a government-funded cultural institution in Prague, targeting local residents, tourists, and academic communities. Its business model is non-profit, focusing on cultural preservation and education rather than commercial gain. Revenue streams likely include ticket sales via its e-shop, venue rentals, and possibly public funding. Partnerships with city authorities and media organizations enhance its outreach. The website's content quality and branding consistency support its authoritative market presence. Growth indicators include active event programming and digital engagement through social media and newsletters.

Security posture

The website demonstrates a moderate to good security maturity level with HTTPS enabled and cookie consent implemented. However, the lack of explicit security headers such as Content Security Policy, X-Frame-Options, and HSTS reduces the overall security score. No vulnerabilities or exposed sensitive data were detected in the analyzed content. The absence of a public security policy or incident response contact limits transparency. The missing WHOIS data is a concern for domain legitimacy verification but may be due to privacy protection. Overall, the security posture is adequate for a cultural institution but could be enhanced by adopting additional best practices and publishing security-related information.

Recommendations

  1. Implement and configure standard security headers (CSP, HSTS, X-Frame-Options) to improve protection against common web attacks.
  2. Publish a clear security policy and incident response contact information to enhance transparency and trust.
  3. Verify and update WHOIS domain registration details to ensure public legitimacy and reduce suspicion.
  4. Conduct regular security audits to identify and remediate any potential vulnerabilities or outdated libraries.
  5. Enhance accessibility features and provide detailed data retention policies to strengthen privacy compliance.

Technical notes

Notes

The website uses a modern tech stack with JavaScript frameworks, Google Tag Manager for analytics, and a cookie consent solution to comply with privacy laws. It loads fonts asynchronously and uses a CDN for widget delivery, indicating good performance optimization. The site is mobile responsive with good SEO metadata and Open Graph tags for social sharing. However, no CMS or backend platform was explicitly detected. Performance is moderate, with room for improvement in loading speed and accessibility. The technical infrastructure supports a professional user experience but could benefit from enhanced security configurations and more detailed technical documentation.
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.
