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

7 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

      Missing X-Frame-Options header

      Prevents clickjacking attacks

      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

The website represents a loyalty program for the Lewiatan retail chain, a significant player in the Polish grocery market. The program incentivizes customers to shop at Lewiatan stores by offering points and vouchers, supported by a mobile app and physical cards. The business leverages digital marketing tools and social media to engage customers. The domain age and WHOIS data align with the business timeline, indicating legitimacy. The company maintains a clear brand presence and provides multiple contact channels. The partnership ecosystem includes related Lewiatan domains and promotional sites. The business model is focused on customer loyalty and retention, with potential revenue streams from increased sales and marketing partnerships.

Security posture

The website demonstrates a moderate security maturity level. HTTPS is properly implemented, and Google reCAPTCHA is used to protect forms. Cookie consent is managed via Cookiebot, supporting GDPR compliance. However, DNSSEC is not enabled, which is a missed opportunity to secure DNS queries. No advanced security headers were detected in the HTML content, suggesting room for improvement. There is no publicly visible security policy or incident response contact information, which could hinder transparency and trust. No exposed sensitive data or vulnerable libraries were identified. Overall, the security posture is adequate but could benefit from enhancements to align with best practices and regulatory requirements.

Recommendations

  1. Enable DNSSEC on the domain to enhance DNS security and prevent spoofing.
  2. Implement additional HTTP security headers such as Content-Security-Policy, X-Content-Type-Options, and X-Frame-Options to mitigate common web attacks.
  3. Publish a clear security policy and provide incident response contact information to improve transparency and user trust.
  4. Regularly audit and update third-party libraries to avoid vulnerabilities from outdated components.
  5. Enhance accessibility features and mobile optimization to improve user experience and compliance.

Technical notes

Notes

The website uses a mature but somewhat dated technology stack including jQuery 3.6.0, Bootstrap 3.4.1, and Vue.js 2.6.10. It integrates several third-party libraries for UI components, data tables, and animations. Cookiebot is used for cookie consent management, and Google Tag Manager is deployed for analytics and marketing tracking. The site is hosted by home.pl, a known Polish hosting provider. Performance is moderate, with some potential for optimization given the number of external scripts and libraries. Mobile optimization is good, with responsive design elements and mobile app promotion. SEO is supported by proper meta tags and structured navigation. No CMS was explicitly detected. Overall, the technical infrastructure is stable but could be modernized to improve performance and maintainability.
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.
