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

Kulturní dům města Holic is a cultural center serving the Holice region in the Czech Republic, offering a wide range of cultural events including concerts, theater performances, exhibitions, and cinema screenings. The organization also provides community services such as costume rental and operates a museum and gallery, positioning itself as a key cultural hub for local residents and visitors. The website reflects a professional and community-oriented business model focused on cultural enrichment and engagement across all age groups. Technically, the website is built on the Webflow platform, utilizing modern web technologies such as Google Fonts, Google Tag Manager, and CAPTCHA services to ensure performance, security, and user experience. The site is mobile optimized, fast loading, and includes SEO best practices, demonstrating a mature digital infrastructure suitable for its audience and business needs. From a security perspective, the site enforces HTTPS, integrates CAPTCHA on forms to prevent abuse, and provides a cookie consent mechanism compliant with GDPR. However, it lacks some advanced security headers and explicit security or incident response policies. No vulnerabilities or suspicious activities were detected, indicating a solid security posture for a small cultural institution. Overall, the website is trustworthy, well-maintained, and aligned with its business purpose. The absence of WHOIS data is likely due to privacy protection and does not detract from the legitimacy of the organization. Strategic recommendations include enhancing security headers, publishing security policies, and continuous monitoring of third-party scripts to maintain security 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.

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

Business profile

Kulturní dům města Holic occupies a vital niche as a cultural and community center in the Holice microregion, leveraging a diverse event portfolio to attract a broad audience. Its competitive advantage lies in its comprehensive cultural offerings and community integration. Revenue streams likely include ticket sales, costume rentals, and possibly grants or municipal funding. The target customers are local residents and visitors interested in cultural activities. The partnership ecosystem includes ticketing platforms and newsletter services, enhancing operational capabilities. Growth indicators include active event scheduling and digital engagement through newsletters and social media. The organization demonstrates a stable operational model with potential for expanded digital marketing and community outreach.

Security posture

The website exhibits a moderate to strong security maturity level appropriate for a small cultural institution. Key strengths include enforced HTTPS, CAPTCHA integration on forms, and GDPR-compliant cookie consent. There are no visible vulnerabilities or exposed sensitive data. Compliance gaps include the absence of explicit security policies and incident response information, which could improve transparency and preparedness. Data protection practices are evident through privacy policies and consent mechanisms. Incident response readiness is unclear due to lack of published information. Overall, the security culture appears adequate but could benefit from formalized policies and enhanced security headers.

Recommendations

  1. Implement HTTP security headers such as Content-Security-Policy, X-Frame-Options, and X-XSS-Protection to strengthen defense against common web attacks.
  2. Publish a dedicated security policy and incident response plan on the website to improve transparency and preparedness.
  3. Regularly audit and update third-party scripts and libraries to mitigate potential vulnerabilities.
  4. Enhance accessibility features to improve inclusivity and compliance with accessibility standards.
  5. Develop a long-term security strategy including periodic penetration testing and staff security awareness training.

Technical notes

Notes

The website is built using Webflow CMS, leveraging modern web technologies including Google Fonts, Google Tag Manager, and Google reCAPTCHA for enhanced user experience and security. Hosting is likely provided by Webflow's CDN infrastructure, ensuring fast content delivery and reliable uptime. The site demonstrates good mobile optimization and SEO practices, with structured navigation and metadata. Technical debt appears minimal, with opportunities for improvement in accessibility and security header implementation. Overall, the technical infrastructure supports the business goals effectively with room for incremental enhancements.
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.
