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.

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 company holds a strong niche position in the Czech sports nutrition market, focusing on direct online sales to consumers. Its competitive advantage lies in a wide product range, including specialized categories like vegan proteins and functional foods, and value-added services such as custom product mixing. The business model is straightforward e-commerce with integrated marketing and analytics tools to drive customer acquisition and retention. The presence of a magazine and educational content supports customer engagement and brand authority. Growth indicators include active marketing pixels and a well-structured product catalog. Partnerships with major ad networks and tracking services suggest a robust marketing ecosystem. No parent or subsidiary companies were identified, indicating an independent operation.

Security posture

The website demonstrates a good security maturity level with HTTPS enforced site-wide and no exposed sensitive data in the HTML content. Use of multiple tracking pixels is managed with cookie consent, reflecting awareness of privacy regulations. However, explicit security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options were not detected in the provided HTML, representing an area for improvement. No vulnerabilities or malware indicators were found. Incident response and security policy documentation are not publicly available, which could be enhanced to improve transparency and readiness. Overall, the security posture is solid but could benefit from additional header implementations and formalized security policies.

Recommendations

  1. Implement comprehensive security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to mitigate common web attacks.
  2. Conduct regular audits of third-party scripts and tracking pixels to ensure no vulnerabilities or privacy risks are introduced.
  3. Enhance accessibility compliance to meet WCAG standards, improving usability for all users.
  4. Publish clear security policies and incident response procedures to increase transparency and preparedness.
  5. Consider obtaining and publishing WHOIS domain registration details to improve domain trustworthiness and legitimacy perception.

Technical notes

Notes

The website uses a modern JavaScript-based front-end framework, likely Vue.js or similar, with module preloading and component-based architecture. It integrates several third-party marketing and analytics services including Google Tag Manager, Facebook Pixel, Bing Ads, and Targito. The site employs responsive design techniques and mobile-optimized carousels (Slick and Swiper) for enhanced user experience. The CMS appears custom or proprietary, tailored for e-commerce. Performance is moderate with asynchronous loading of scripts and preconnect hints for fonts. No major technical debt or deprecated technologies were detected. Opportunities exist to improve security headers and accessibility features 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.
