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

The website handpan-kurz.cz is a small-scale educational platform focused on teaching handpan music, primarily through in-person courses and workshops led by Jiří Káš, a recognized handpan player in the Czech Republic. The site offers rich content including detailed explanations, images, and links to related handpan resources and artists, targeting individuals interested in learning and mastering the handpan instrument. Technically, the site is built on WordPress using the Donovan theme, hosted by a Czech hosting provider, and employs modern web technologies such as JavaScript and SVG icons. The site is mobile-optimized and provides a good user experience with clear navigation and relevant content. Security-wise, the site uses HTTPS but lacks security headers and formal privacy or cookie policies, which limits its compliance posture. No contact emails or phone numbers are explicitly provided, which may affect user trust and business credibility. Overall, the site is legitimate and consistent with its domain registration data, but improvements in privacy compliance and security best practices are recommended.

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

  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 X-Frame-Options header

      Prevents clickjacking attacks

      What to do: Add "X-Frame-Options: DENY" or "X-Frame-Options: SAMEORIGIN"

    • 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

Handpan-kurz.cz operates in a niche market segment focused on musical education for handpan enthusiasts. Its competitive advantage lies in the expertise of Jiří Káš and the provision of specialized, in-person courses that are not widely available. The business model is primarily service-based, offering workshops and courses, supplemented by online content and promotional materials. The target customers are music learners in the Czech Republic and Slovakia, with some international interest. The website references partnerships with related handpan sites and artists, indicating a collaborative ecosystem. Growth potential exists through expanding online offerings and improving digital marketing. The absence of direct contact information and formal policies may limit trust and conversion rates.

Security posture

The website demonstrates a basic security posture with HTTPS enabled, ensuring encrypted communications. However, it lacks important security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options, which are recommended to mitigate common web vulnerabilities. No forms or input fields are present on the main page, reducing attack surface, but also limiting user interaction. There is no evidence of vulnerability disclosure or incident response policies, which are important for security maturity. Privacy compliance is weak due to missing privacy and cookie policies, which may expose the business to regulatory risks under GDPR. Overall, the security posture is functional but could be significantly improved with standard best practices and compliance measures.

Recommendations

  1. Implement and publish a comprehensive privacy policy and cookie policy to improve GDPR compliance.
  2. Add standard security headers (Content-Security-Policy, X-Frame-Options, X-Content-Type-Options) to enhance protection against common attacks.
  3. Provide clear contact information including emails and phone numbers to improve business credibility and user trust.
  4. Consider adding a vulnerability disclosure policy or security.txt file to demonstrate security transparency.
  5. Regularly update WordPress core, themes, and plugins to mitigate potential vulnerabilities and maintain security hygiene.

Technical notes

Notes

The website is built on WordPress CMS with the Donovan theme, leveraging JavaScript libraries such as CanvasJS and SVG icon sets for UI elements. Hosting is provided by Cesky Hosting, a Czech hosting provider, with DNS configured accordingly. The site uses HTTPS with valid SSL certificates, ensuring secure data transmission. Performance is moderate with good mobile optimization and basic accessibility features. SEO optimization is basic, with meta tags present but no advanced structured data like JSON-LD or Open Graph tags detected. No analytics or tracking scripts were found, indicating minimal user tracking. The site lacks forms or interactive elements, limiting data collection but also reducing complexity and attack surface. Overall, the technical infrastructure is solid for a small educational site but could benefit from enhanced SEO, accessibility, and security features.
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.
