Risk levelHigh

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

Muzeum města Brna is a well-established cultural institution dedicated to preserving and showcasing the history and heritage of Brno, Czech Republic. The website reflects a medium-sized government/non-profit entity with a strong focus on exhibitions, educational programs, and cultural events. It serves a broad audience including tourists, local citizens, and educational institutions. The digital presence is supported by a modern tech stack including jQuery, Bootstrap, and Google services, with good mobile optimization and user experience. Privacy and cookie compliance are well implemented with clear consent mechanisms and GDPR adherence. Security posture is solid with HTTPS and reCAPTCHA integration, though improvements in security headers and explicit policies are recommended. The absence of WHOIS data limits domain trust assessment but the website's professional presentation and official partnerships indicate legitimacy.

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

9 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

      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 operates primarily in the government and non-profit sectors, focusing on cultural heritage and education. It leverages partnerships with local historical sites and city authorities, enhancing its market position as a key cultural institution in Brno. Revenue streams likely include public funding, ticket sales, venue rentals, and educational services. The website's content and navigation cater well to its target audience, supporting engagement and outreach. The presence of social media and external partner links indicates an integrated digital ecosystem. Growth opportunities may include enhanced digital experiences and expanded virtual tours.

Security posture

The website demonstrates a mature security posture with enforced HTTPS, use of Google reCAPTCHA v3 to protect forms, and cookie consent management aligned with GDPR. Email addresses are obfuscated to reduce spam risk. However, the lack of visible HTTP security headers such as CSP, HSTS, and X-Frame-Options represents an area for improvement. No vulnerabilities or exposed sensitive data were detected in the HTML content. Incident response and security policies are not explicitly published, which could be enhanced to improve transparency and readiness. Overall, the security measures are adequate for the institution's risk profile but could benefit from formalized policies and additional technical controls.

Recommendations

  1. Implement HTTP security headers including Content Security Policy (CSP), HTTP Strict Transport Security (HSTS), and X-Frame-Options to enhance protection against common web attacks.
  2. Publish explicit security and incident response policies on the website to improve transparency and preparedness.
  3. Regularly audit and update third-party libraries and plugins to mitigate potential vulnerabilities.
  4. Consider adding a security.txt file to facilitate responsible vulnerability disclosure.
  5. Enhance accessibility features to improve compliance with standards and user inclusivity.

Technical notes

Notes

The website is built on a custom or Nette-based CMS platform utilizing a modern JavaScript and CSS stack including jQuery, Bootstrap, FontAwesome, and Moment.js. It integrates Google Fonts and Google Analytics for typography and analytics respectively. Performance is moderate with lazy loading of images and asynchronous script loading. Mobile optimization is good with responsive design and viewport meta tags. Accessibility is basic but could be improved. SEO is supported by proper meta tags, Open Graph tags, and JSON-LD structured data for website and search actions. The site uses Google reCAPTCHA v3 for spam protection and a cookie consent plugin for privacy compliance. Overall, the technical infrastructure is solid but could benefit from enhanced security headers and accessibility improvements.
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.
