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

Košík.cz is a prominent Czech online grocery retailer offering a wide range of food products with bulk discounts, free delivery on large orders, and loyalty programs. The website targets Czech consumers looking for convenient online grocery shopping solutions. The business model focuses on e-commerce retail with promotional incentives to attract and retain customers. The company appears to hold a strong market position within the Czech Republic's online grocery sector. Technically, the website leverages modern frontend technologies such as Vue.js and integrates Google Tag Manager for analytics and marketing purposes. The site is mobile-optimized with good SEO practices and basic accessibility features. Performance is moderate, with a clean and professional design that supports a positive user experience. From a security perspective, the site enforces HTTPS and includes several important security headers, indicating a good baseline security posture. However, the absence of visible privacy and cookie policies, incident response information, and vulnerability disclosure mechanisms suggests areas for improvement in compliance and transparency. No critical vulnerabilities or exposed sensitive data were detected. Overall, the website is trustworthy and professional, but the lack of WHOIS data and privacy-related disclosures slightly reduce the confidence level. Strategic recommendations include publishing comprehensive privacy and cookie policies, establishing a vulnerability disclosure process, and enhancing accessibility and security transparency to strengthen user trust and compliance.

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

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

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

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

Košík.cz operates in the retail and e-commerce sectors, specializing in online grocery sales in the Czech Republic. The company differentiates itself through bulk purchase discounts (Multikup), free delivery on large orders, and weekly promotional flyers. Its target customers are Czech consumers seeking convenience and value in grocery shopping. The business model is direct-to-consumer online retail with loyalty incentives. The website's content and structured data indicate a large-sized enterprise with a consistent brand presence. The absence of WHOIS data limits external verification but does not detract from the site's professional presentation and clear contact information. The company likely generates revenue through product sales and promotional partnerships. No parent or subsidiary companies were identified in the data provided.

Security posture

The website demonstrates a solid security foundation with HTTPS enforced and multiple security headers implemented, including HSTS, X-Content-Type-Options, and Content-Security-Policy. No signs of exposed credentials, vulnerable libraries, or insecure forms were found in the HTML content. However, the site lacks publicly available security policies, incident response contacts, or vulnerability disclosure information, which are important for transparency and compliance with regulations such as GDPR and NIS2. The absence of a security.txt file or similar mechanism reduces the ease of reporting security issues. Overall, the security posture is good but could be enhanced by adding formal security governance documentation and incident response details.

Recommendations

  1. Publish a comprehensive privacy policy and cookie policy with clear GDPR compliance statements and consent mechanisms.
  2. Implement a security.txt file or dedicated vulnerability disclosure page to facilitate responsible reporting of security issues.
  3. Add incident response and security policy information accessible to users and partners to improve transparency.
  4. Enhance website accessibility features to meet higher standards and improve user experience for all visitors.
  5. Regularly audit and update third-party scripts and libraries to mitigate potential vulnerabilities and maintain security hygiene.

Technical notes

Notes

The website is built using Vue.js, a modern JavaScript framework, indicating a contemporary frontend architecture. It uses Google Tag Manager for analytics and marketing tracking. The site includes responsive design elements and meta tags optimized for SEO and social media sharing (Open Graph and Twitter cards). Performance appears moderate with skeleton loaders for product images, suggesting asynchronous content loading. No CMS was explicitly detected. Hosting provider details are not available from the HTML content. The technical implementation is solid but could benefit from enhanced accessibility and performance optimizations. No critical technical debt or outdated technologies were observed.
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.
