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

8 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 Policy found

      GDPR requires clear information about cookie usage

      What to do: Add a dedicated cookie policy explaining cookie usage and purposes

  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

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 website positions itself strongly within the cultural heritage sector, leveraging partnerships with municipal and cultural institutions to enhance credibility and reach. Its business model is focused on cultural tourism and education, with diversified revenue streams including ticket sales, event hosting, and merchandise. The target audience includes general visitors, tourists, and schools, indicating a broad market approach. The presence of multiple recognized partners and official backing by the City of Prague strengthens its market position. Growth potential lies in expanding digital engagement and enhancing online services. The partnership ecosystem is robust, involving museums, tourism boards, and local government entities.

Security posture

The security maturity level is moderate. The website uses HTTPS and includes CSRF tokens, indicating awareness of basic web security practices. However, the absence of security headers such as Content Security Policy, HSTS, and X-Frame-Options reduces the overall security posture. No explicit incident response or security policy pages are found, which may impact readiness for security incidents. The use of third-party scripts like Google Analytics and Google Maps introduces typical risks but no vulnerable libraries or exposed sensitive data were detected. Compliance with GDPR is indicated but could be improved with explicit cookie consent and detailed data retention policies. Overall, the site is secure for general use but would benefit from enhanced security controls and transparency.

Recommendations

  1. Implement comprehensive security headers including CSP, HSTS, and X-Frame-Options to mitigate common web attacks.
  2. Add a clear cookie consent banner/mechanism to improve GDPR compliance and user transparency.
  3. Publish a dedicated security policy and incident response contact information to enhance trust and preparedness.
  4. Regularly audit and update third-party scripts to avoid vulnerabilities and reduce attack surface.
  5. Enhance accessibility features and provide detailed data retention and privacy policies to strengthen compliance and user trust.

Technical notes

Notes

The website is built on a modern technology stack with Ruby on Rails inferred from Turbolinks and CSRF meta tags. It integrates Google Analytics, Google Tag Manager, and Google Maps API for analytics and mapping functionalities. Hosting is provided by Active24, a known Czech hosting provider. The site demonstrates good mobile optimization and SEO practices with proper meta tags and structured navigation. Performance is moderate, with potential improvements in loading speed and accessibility. The use of PhotoSwipe indicates attention to user experience for media content. Technical debt appears low, but security header implementation and cookie consent mechanisms are areas for modernization.
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.
