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

      Missing Strict-Transport-Security header

      Forces HTTPS connections

      What to do: Add "Strict-Transport-Security: max-age=31536000; includeSubDomains; preload"

      • OWASP A04:2025
      • ASVS V3.4.1
    • High

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 business operates in a niche wellness and yoga market within the Czech Republic, leveraging multiple digital channels including social media, podcasts, and online courses to engage its audience. Partnerships with e-commerce and travel platforms enhance its service offerings. The company targets individuals interested in yoga, breathing, and holistic health, providing both free content and paid programs. The website's clear navigation, comprehensive program listings, and active social media presence indicate a mature digital strategy. Revenue streams likely include class fees, book sales, retreats, and online subscriptions. The brand maintains a consistent and professional image, supporting growth and customer trust.

Security posture

The website demonstrates a moderate to good security posture with HTTPS enabled and cookie consent implemented for analytics tracking. However, the absence of explicit security headers such as Content-Security-Policy and X-Frame-Options reduces defense-in-depth. No forms collecting sensitive data were detected on the homepage, minimizing immediate risk. The lack of published security policies or incident response contacts suggests room for improvement in transparency and preparedness. No vulnerabilities or suspicious patterns were found in the content or WHOIS data. Overall, the site is secure for its business scope but could enhance security maturity by adopting additional best practices.

Recommendations

  1. Implement HTTP security headers including Content-Security-Policy, X-Content-Type-Options, and X-Frame-Options to strengthen protection against common web attacks.
  2. Publish a dedicated security policy and incident response page to improve transparency and user trust.
  3. Consider adding a security.txt file to facilitate responsible vulnerability disclosure.
  4. Regularly audit third-party scripts and dependencies to ensure no vulnerable libraries are used.
  5. Enhance accessibility features and provide more detailed SEO metadata to improve user experience and search visibility.

Technical notes

Notes

The website uses a combination of jQuery, Bootstrap CSS, and Font Awesome for UI and styling, with Google Fonts for typography. Analytics and tag management are handled via Google Analytics and Google Tag Manager, integrated with a cookie consent plugin to comply with privacy laws. The site appears custom-built or uses a proprietary CMS, with no common CMS signatures detected. Performance is moderate with asynchronous script loading and responsive design for mobile devices. Accessibility is basic but functional. The site lacks advanced frameworks or platforms but is stable and well-maintained. Opportunities exist to modernize the tech stack and improve security headers and accessibility compliance.
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.
