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

Czech Virtuosi, z.s. is a non-profit cultural organization based in the Czech Republic that organizes classical music concerts and international music competitions. The organization is supported by local government entities such as the city of Brno and the South Moravian Region, reflecting a strong regional presence and community engagement. Their website serves as a portal for event information, ticket sales, and news updates, targeting classical music enthusiasts and cultural event attendees. The business model relies on sponsorships, government funding, and ticket sales to sustain its activities. Technically, the website is built using modern web technologies including React and slick carousel for interactive content presentation. It is mobile-optimized and provides a good user experience with clear navigation and professional design. Google Analytics is used for visitor tracking, though privacy compliance could be improved by implementing cookie consent mechanisms. The website lacks explicit security headers and incident response policies, which are areas for enhancement. From a security perspective, the site uses HTTPS and does not expose sensitive data in its HTML content. However, the absence of WHOIS data limits the ability to fully verify domain legitimacy and ownership transparency. No critical vulnerabilities or security issues were detected in the visible content. The organization should consider publishing security policies and improving GDPR compliance measures to strengthen trust. Overall, Czech Virtuosi presents a professional and trustworthy online presence for a small non-profit cultural entity. Strategic improvements in security posture and privacy compliance will enhance their digital maturity and stakeholder confidence.

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

  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

      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

Czech Virtuosi operates in the non-profit cultural sector, focusing on classical music events primarily in the Czech Republic. Their market positioning is strong regionally, supported by partnerships with local government and sponsors. The organization leverages a business model based on event organization, sponsorship, and community engagement. Key revenue streams likely include ticket sales and government grants. The target customer segments are classical music audiences and cultural event attendees. The partnership ecosystem includes municipal and regional governments, local businesses, and service providers such as SOVA NET. Growth indicators include recurring annual events and international music competitions. The website reflects a stable operational presence with professional content and consistent branding.

Security posture

The website demonstrates a moderate security maturity level with HTTPS enabled and no visible exposure of sensitive data. However, the lack of security headers such as Content Security Policy, HSTS, and X-Frame-Options reduces protection against common web attacks. No incident response or security policy information is published, indicating limited transparency in security governance. GDPR compliance is partially addressed through a privacy policy, but the absence of a cookie consent mechanism is a compliance gap. The use of third-party scripts like Google Analytics introduces moderate tracking risk. Overall, the security posture is adequate for a small non-profit but requires improvements to meet higher compliance and security standards.

Recommendations

  1. Implement comprehensive security headers including CSP, HSTS, and X-Frame-Options to enhance web security.
  2. Add a cookie consent banner to comply fully with GDPR and improve user privacy transparency.
  3. Publish explicit security policies and incident response procedures on the website to increase trust and preparedness.
  4. Conduct regular audits of third-party scripts and dependencies to mitigate potential vulnerabilities.
  5. Enhance accessibility features to improve inclusivity and meet web standards.

Technical notes

Notes

The website uses a modern React-based front-end with slick carousel for interactive content display. It loads CSS and JavaScript assets efficiently and is mobile responsive. Google Analytics is integrated for visitor tracking. The site lacks advanced SEO meta tags and accessibility features could be improved. Hosting provider details are not disclosed. Performance is moderate with no major issues detected. The absence of a CMS suggests a custom or static site architecture. Technical debt appears low but security and privacy implementations need enhancement to align with best practices.
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.
