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. 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 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';…
  2. GDPR outside view

    These are the privacy signals visitors and data protection authorities look for under GDPR.

    • 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

    • High

      No Cookie Policy found

      GDPR requires clear information about cookie usage

      What to do: Add a dedicated cookie policy explaining cookie usage and purposes

    • High

      No Cookie Consent Banner found

      GDPR requires explicit consent for non-essential cookies

      What to do: Implement a cookie consent banner that appears on first visit

    • High

      Third-party services without privacy policy

      Detected services: Google Analytics, Facebook, Twitter, LinkedIn, YouTube

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

Heureka Group holds a strong market position as a leading e-commerce service provider in Slovakia and Czechia, focusing on advertising and data services for online shops and brands. Their business model revolves around providing marketing tools, data insights, and partner programs that enable e-commerce growth. The company targets e-shops and brands seeking to optimize their online presence and sales performance. The presence of affiliate programs and partnerships with related domains like ShopRoku and ProduktRoku indicates a well-developed ecosystem. The active blog and webinar offerings suggest a strategy to educate and engage their customer base, supporting customer retention and acquisition. The company appears to be large in size, with consistent branding and a professional online footprint.

Security posture

The website demonstrates a solid security posture with HTTPS enforced and integration of consent management frameworks ensuring GDPR compliance. However, the absence of visible security headers such as Content Security Policy (CSP), HTTP Strict Transport Security (HSTS), and X-Frame-Options reduces the overall security robustness. No exposed sensitive data or vulnerable libraries were detected in the HTML content. The site lacks explicit incident response or security contact information, which is a gap in transparency and readiness. The use of third-party scripts like Visual Website Optimizer and Didomi is well-managed but requires ongoing monitoring to prevent supply chain risks. Overall, the security posture is good but can be improved by implementing recommended headers and publishing security policies.

Recommendations

  1. Implement and enforce security headers including CSP, HSTS, and X-Frame-Options to enhance protection against common web attacks.
  2. Publish a dedicated security policy page and provide clear incident response contact information to improve transparency and trust.
  3. Regularly audit and update third-party scripts and libraries to mitigate supply chain vulnerabilities.
  4. Enhance accessibility features to improve compliance and user experience for all visitors.
  5. Maintain and update privacy and cookie policies to reflect evolving regulations and best practices.

Technical notes

Notes

The website uses a modern technology stack including Google Tag Manager for analytics, Visual Website Optimizer for A/B testing, and Didomi for consent management, indicating a mature digital marketing infrastructure. The site is built with standard HTML5, CSS, and JavaScript, with no detected CMS from the source. Performance is moderate with asynchronous loading of scripts and preloading of CSS assets. Mobile optimization is good, with responsive design elements and accessible navigation. SEO is supported by proper meta tags and Open Graph data. There is no explicit hosting provider identified from the HTML content. The site could benefit from enhanced accessibility features and performance optimizations to improve user experience further.
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.
