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

Kupi.cz is a Czech online platform specializing in aggregating promotional leaflets, discounts, and retail offers from various stores, targeting consumers seeking savings and shopping inspiration. The website offers additional services such as shopping lists and a mobile app for leaflet browsing, positioning itself as a leading retail promotions aggregator in the Czech market. Technically, the site employs modern web technologies including jQuery, Google Tag Manager, Facebook Pixel, and integrates with advertising networks like Google DoubleClick and Seznam SSP. The site is mobile-optimized with responsive design and basic accessibility features. Security-wise, the website enforces HTTPS and uses consent management for analytics and advertising, but lacks explicit privacy and cookie policy pages, which impacts privacy compliance. The absence of WHOIS data limits domain legitimacy verification, although the site appears professional and trustworthy based on content and branding. Overall, Kupi.cz demonstrates a mature digital presence with room for improvement in privacy transparency and security header implementation.

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.

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

Kupi.cz operates in the retail and media sectors, providing a valuable service by consolidating promotional leaflets from major Czech retailers such as Tesco, Albert, Lidl, and Kaufland. Its business model revolves around attracting consumers interested in discounts and promotions, likely monetizing through advertising and affiliate partnerships (e.g., Alza.cz affiliate links). The platform targets general consumers in the Czech Republic, offering content in Czech language and localized offers. The presence of multiple retail partners and a mobile app indicates a medium-sized operation with a strong market position in the Czech retail promotions niche. The website's integration with major ad networks and tracking services suggests a focus on data-driven marketing and monetization strategies.

Security posture

The website maintains a good security posture with HTTPS enabled and integration of consent management platforms to control user data collection. Security headers are partially implemented or inferred but could be enhanced with explicit policies such as Referrer-Policy and Permissions-Policy. No exposed sensitive data or vulnerable libraries were detected in the HTML content. The site uses reputable third-party analytics and advertising services, but the reliance on multiple external scripts requires ongoing monitoring for vulnerabilities. The lack of visible security or incident response policies and absence of contact channels for security issues represent gaps in the security maturity. Overall, the site is secure for general consumer use but would benefit from improved transparency and formal security documentation.

Recommendations

  1. Publish clear and accessible privacy and cookie policy pages to improve GDPR compliance and user trust.
  2. Implement additional security headers such as Referrer-Policy and Permissions-Policy to enhance browser security.
  3. Provide visible contact information or a dedicated security contact channel for incident reporting and response.
  4. Regularly audit and update third-party scripts and libraries to mitigate potential vulnerabilities.
  5. Enhance accessibility features to meet recognized standards and improve user experience for all visitors.

Technical notes

Notes

The website uses a modern tech stack with jQuery, Google Tag Manager, Facebook Pixel, and integrates with multiple ad networks including Google DoubleClick and Seznam SSP. It employs web fonts and responsive CSS for mobile optimization. The site loads asynchronously many scripts to improve performance but could benefit from further optimization. No CMS was explicitly detected. Hosting provider details are not available from the HTML content. The site demonstrates good SEO practices with meta tags, Open Graph, and Twitter card metadata. Accessibility is basic but present. Overall, the technical implementation supports a robust and user-friendly retail promotions platform.
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.
