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

10 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

    • High

      Missing Strict-Transport-Security header

      Forces HTTPS connections

      What to do: Add "Strict-Transport-Security: max-age=31536000; includeSubDomains; preload"

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 entity serving the Moravian-Silesian Region. Its business model is non-commercial, focusing on public cultural preservation and education. The institution benefits from regional government backing, which supports its legitimacy and operational stability. The website integrates social media and newsletter tools to engage visitors and promote events. There is no evidence of commercial revenue streams beyond public funding and possibly venue rentals. The partnership with NETservis s.r.o. for web services indicates a professional digital presence. Growth indicators include active event programming and multiple site management. Strategic observations suggest opportunities to enhance digital security policies and incident response transparency.

Security posture

The website demonstrates a mature security posture with HTTPS enforced and a comprehensive cookie consent mechanism that respects user privacy and GDPR requirements. The absence of visible vulnerabilities or exposed sensitive data is positive. However, the lack of published security policies, incident response contacts, and advanced security headers such as Content-Security-Policy or X-Content-Type-Options represents areas for improvement. The use of third-party scripts like Google Tag Manager and Mailservis is managed with consent, reducing privacy risks. Overall, the security culture appears adequate for a public institution but could benefit from formalized documentation and enhanced header configurations.

Recommendations

  1. Publish a dedicated security policy page outlining security practices and user guidance.
  2. Provide clear incident response contact information to improve transparency and readiness.
  3. Implement additional HTTP security headers (e.g., Content-Security-Policy, X-Content-Type-Options) to harden the site.
  4. Regularly audit and update third-party libraries and scripts to mitigate vulnerabilities.
  5. Enhance accessibility features to improve compliance and user experience for all visitors.

Technical notes

Notes

The website employs a traditional web stack with jQuery 3.2.1 and Google Tag Manager for analytics and marketing integration. Cookie consent is managed by KookieCheck, ensuring GDPR compliance. The site loads CSS and JS resources efficiently, with some use of minified scripts. Performance is moderate, with room for optimization. Mobile responsiveness is good, supported by viewport meta tags and adaptive navigation. SEO is supported by meta keywords, descriptions, and structured navigation menus. No CMS is explicitly detected, suggesting a custom or proprietary platform. Hosting provider details are not disclosed. Technical risks are minimal but include potential outdated jQuery version and missing advanced security headers.
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.
