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.

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

  2. Security headers

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 positions itself as a local niche player in the sports nutrition retail market in the Czech Republic and Slovakia. It leverages both online and offline sales channels, with a physical store in Brno. The company offers member benefits such as discounts and order history tracking, which supports customer retention. The integration with Heureka.cz suggests participation in local e-commerce comparison platforms, enhancing visibility. The presence of social media links and live chat support indicates active customer engagement. The business model is straightforward retail with a focus on quality brands at competitive prices. No parent or subsidiary companies are identified, indicating an independent small business operation.

Security posture

The website uses HTTPS and includes standard marketing and analytics scripts. However, it lacks explicit security headers such as Content-Security-Policy and X-Frame-Options, which are recommended to mitigate common web attacks. The use of an outdated jQuery version (1.8.1) presents potential security vulnerabilities. No sensitive data exposure or obvious vulnerabilities were detected in the HTML content. Privacy policies are present but the absence of a cookie consent mechanism may be a GDPR compliance gap. Incident response and security policy information are not found, indicating limited transparency in security governance. Overall, the security posture is moderate but could be significantly improved with updated libraries, security headers, and enhanced privacy compliance.

Recommendations

  1. Update jQuery and other JavaScript libraries to current secure versions to mitigate known vulnerabilities.
  2. Implement and configure security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  3. Add a cookie consent banner/mechanism to comply fully with GDPR requirements.
  4. Publish a clear security policy and incident response contact information to improve transparency and trust.
  5. Conduct regular security audits and penetration testing to identify and remediate potential vulnerabilities.

Technical notes

Notes

The website uses a traditional HTML structure with CSS and JavaScript enhancements. It relies on jQuery 1.8.1, Fancybox for image display, and integrates multiple third-party scripts for analytics and marketing, including Google Tag Manager, Google Analytics, Facebook Pixel, and SmartSupp Live Chat. The site loads resources asynchronously to improve performance. Mobile optimization is basic but functional. SEO is supported by meta tags and structured navigation. The site does not appear to use a known CMS, suggesting a custom or legacy platform. Hosting provider details are not discernible from the content. Performance is moderate with room for improvement in modernizing the tech stack and enhancing accessibility 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.
