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

Pěvecký sbor DVOŘÁK Uherský Brod is a small non-profit choir organization based in the Czech Republic, focused on choral singing and cultural events. The website serves as a portal for choir information, event announcements, and recruitment of new singers. It maintains an active presence on social media platforms such as Facebook, Instagram, and YouTube, supporting community engagement and outreach. The business model centers on cultural promotion and community participation rather than commercial activities. Technically, the website is built on the Webnode CMS platform and hosted via AWS Cloudfront CDN, ensuring reliable delivery and moderate performance. The site uses modern web technologies including JavaScript and CSS, and integrates Google Tag Manager for analytics and tracking. Mobile optimization and responsive design are adequately implemented, providing a good user experience across devices. From a security perspective, the website enforces HTTPS, which is a critical baseline for secure communications. However, it lacks several important security headers that could enhance protection against common web vulnerabilities. No privacy or cookie policies are present, which is a compliance gap especially under GDPR regulations. The absence of WHOIS data due to privacy protection slightly reduces trust but is understandable for a small cultural entity. No forms collecting sensitive data were detected on the homepage, reducing immediate risk. Overall, the website is functional, safe, and serves its community purpose well, but it would benefit from improved security practices and formalized privacy compliance. Strategic recommendations include implementing security headers, publishing privacy and cookie policies with consent mechanisms, and enhancing accessibility features to broaden inclusivity.

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

      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 choir operates in the cultural and community sector, targeting local and regional audiences interested in choral music and cultural events. Its competitive advantage lies in its active participation in festivals and concerts, as well as its openness to new members. The business model is non-commercial, focusing on cultural enrichment and community engagement. Revenue streams are likely limited to donations, event ticket sales, and possibly grants. The partnership ecosystem includes social media platforms and event venues. Growth indicators include ongoing event participation and active recruitment. The organization maintains a consistent brand and professional online presence, supporting its reputation in the local cultural scene.

Security posture

The current security maturity is moderate. HTTPS is properly implemented, ensuring encrypted communication. However, the absence of security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options exposes the site to potential risks like clickjacking and MIME sniffing. No evidence of vulnerable libraries or exposed sensitive data was found. The lack of privacy and cookie policies indicates compliance gaps with GDPR and related regulations. Incident response and security contact information are not provided, limiting readiness for security events. Overall, the security posture is adequate for a small non-profit but requires enhancements to meet best practices and regulatory requirements.

Recommendations

  1. Implement essential security headers (Content-Security-Policy, X-Frame-Options, X-Content-Type-Options) to mitigate common web vulnerabilities.
  2. Publish comprehensive privacy and cookie policies with explicit user consent mechanisms to ensure GDPR compliance.
  3. Add terms of service and incident response contact details to improve transparency and readiness.
  4. Enhance website accessibility features to comply with standards and improve user experience for all visitors.
  5. Regularly review and update WHOIS information to improve domain transparency and trustworthiness.

Technical notes

Notes

The website is built on the Webnode CMS platform, leveraging AWS Cloudfront CDN for hosting and content delivery, which supports scalability and performance. The technology stack includes modern HTML5, CSS, and JavaScript, with integration of Google Tag Manager for analytics. The site is mobile responsive and has a clear navigation structure. However, the absence of security headers and formal privacy mechanisms indicates technical debt in security and compliance areas. Performance is moderate, with potential for optimization in loading times and accessibility. The site does not expose forms on the homepage, reducing attack surface but limiting direct user interaction for data collection.
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.
