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

9 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"

      • CWE-319
      • OWASP A04:2025
      • ASVS V3.4.1
    • High

      What to do: Add "X-Frame-Options: DENY" or "X-Frame-Options: SAMEORIGIN"

    • High

      Missing Content-Security-Policy header

      Controls resources the browser is allowed to load

      What to do: Implement a Content-Security-Policy appropriate for your application

      • ASVS V3.4.3
      • OWASP Secure Headers: OWASP Secure Headers Project recommends Content-Security-Policy: default-src 'self'; form-action 'self'; base-uri 'self'; object-src 'none';…

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 sector with an e-commerce business model focused on online grocery sales. The company leverages partnerships with well-known brands and offers promotions and loyalty incentives to attract and retain customers. The website content and structure indicate a mature digital presence with good user experience and mobile optimization. The absence of WHOIS data and privacy policies suggests areas for compliance improvement. The company appears to be a significant player in the Czech market with a large customer base and extensive product offerings.

Security posture

The website enforces HTTPS and uses modern frontend frameworks, which is positive for security. However, the lack of visible security headers such as Content-Security-Policy and absence of published security policies or incident response contacts indicate room for improvement. No vulnerabilities or exposed sensitive data were detected in the HTML content. The use of third-party analytics and marketing tools introduces moderate tracking, which should be balanced with privacy compliance measures. Overall, the security posture is adequate but could be enhanced by implementing best practices and transparency.

Recommendations

  1. Publish comprehensive privacy and cookie policies clearly accessible from the website footer.
  2. Implement and configure security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  3. Provide explicit incident response and vulnerability disclosure contacts or pages.
  4. Improve WHOIS transparency or provide domain registration details publicly to enhance trust.
  5. Regularly audit third-party scripts and tracking to ensure GDPR compliance and minimize user tracking.

Technical notes

Notes

The website uses Vue.js as its primary frontend framework, indicating a modern and dynamic user interface. It integrates Google Tag Manager and Google Analytics for marketing and analytics purposes. The site is mobile optimized and uses responsive images and layouts. Performance appears moderate with some skeleton loading placeholders visible in product carousels, suggesting asynchronous content loading. No CMS or hosting provider details were identified from the HTML. The technical implementation is solid but could benefit from enhanced accessibility features and security header configurations.
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.
