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

Musica sacra is a Czech non-profit organization dedicated to the promotion and enhancement of church liturgical music. Founded in 2006, it offers educational courses for organists, organizes events, publishes newsletters and music, and supports the community of church musicians. The website serves as a hub for information, resources, and event announcements targeting church musicians, choir members, and liturgical music enthusiasts primarily in the Czech Republic. Technically, the website uses a modern tech stack including jQuery, Bootstrap 4.6, FontAwesome, and Owl Carousel, with Cloudflare DNS and Matomo analytics for privacy-conscious user tracking. The site is mobile-optimized and provides a good user experience with clear navigation and professional design. However, it lacks explicit privacy and cookie policies, which is a compliance gap. From a security perspective, the site enforces HTTPS and uses Cloudflare DNS but does not implement key security headers such as Content-Security-Policy or HSTS. No vulnerabilities or exposed sensitive data were detected in the content. The WHOIS data is consistent with the website's Czech origin and long-standing presence, supporting legitimacy. Overall, the site is trustworthy and professional but would benefit from improved privacy compliance and enhanced security headers to strengthen its security posture and regulatory adherence.

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. Email security

    SPF, DKIM and DMARC stop others sending email that looks like it comes from your domain, a common route to phishing and invoice fraud.

    • Critical

      No email authentication configured

      Domain is vulnerable to email spoofing

      What to do: Implement SPF, DKIM, and DMARC immediately

  3. 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"

      • CWE-319
      • OWASP A04:2025
      • ASVS V3.4.1
    • High

      Missing Content-Security-Policy header

      Controls resources the browser is allowed to load

      What to do: Implement a Content-Security-Policy appropriate for your application

      • ASVS V3.4.3
      • OWASP Secure Headers: OWASP Secure Headers Project recommends Content-Security-Policy: default-src 'self'; form-action 'self'; base-uri 'self'; object-src 'none';…

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

Musica sacra occupies a niche market in the Czech Republic focused on church music and liturgical culture. Its competitive advantage lies in its specialized educational offerings, event organization, and community engagement. The business model is non-profit, relying on donations (via donator.cz) and possibly sales of publications. The target customers are church musicians, organists, choir members, and liturgical music supporters. The organization maintains partnerships with related sites such as proscholy.cz and regenschori.cz, enhancing its ecosystem. Growth indicators include ongoing event scheduling and active publication updates. The website reflects a stable, small-sized organization with a clear mission and consistent branding.

Security posture

The website demonstrates a moderate security maturity level. HTTPS is enforced, and Cloudflare DNS is used, which provides some protection and reliability. However, the absence of critical security headers such as Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security reduces the overall security posture. No incident response or security policy information is publicly available, indicating potential gaps in transparency and readiness. The use of Matomo analytics suggests some privacy awareness. There are no visible vulnerabilities or exposed sensitive data, but the site should improve compliance with GDPR by publishing privacy and cookie policies and implementing consent mechanisms.

Recommendations

  1. Implement and publish a comprehensive privacy policy and cookie policy with GDPR compliance details.
  2. Add security headers including Content-Security-Policy, X-Frame-Options, X-Content-Type-Options, and Strict-Transport-Security to enhance protection.
  3. Establish and disclose an incident response policy and contact channels for security issues.
  4. Regularly audit third-party scripts and libraries to ensure no vulnerabilities are introduced.
  5. Enhance accessibility features and SEO metadata to improve user experience and search engine ranking.

Technical notes

Notes

The website uses a combination of jQuery, Bootstrap 4.6, FontAwesome, and Owl Carousel for UI and interactivity, hosted on a server with Cloudflare DNS. Matomo analytics is used for tracking, indicating a preference for privacy-friendly tools. The site is mobile responsive and has a professional design. However, there is no indication of a popular CMS, suggesting a custom or proprietary system. Performance is moderate, with some external dependencies on Google Fonts and third-party scripts. The site lacks advanced security headers and privacy compliance features, which are technical risks. Overall, the infrastructure is stable but could benefit from modernization and enhanced security configurations.
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.
