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

6 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

    • 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

  2. SSL/TLS

    TLS encrypts the connection and proves the site is really yours. Weak or expiring certificates trigger browser warnings and put traffic at risk.

    • Critical

      Unable to retrieve SSL certificate

      Could not establish secure connection to retrieve certificate information

      What to do: Check if the server is accessible and SSL/TLS is properly configured

  3. 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';…

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

DATART holds a strong market position as a major electronics retailer in the Czech Republic, leveraging both e-commerce and physical retail channels. Their business model focuses on fast product availability and delivery, appealing to a broad consumer base. The partnership with Euronics Group suggests strategic alliances enhancing market reach. The website's extensive product taxonomy and marketing integrations indicate a sophisticated digital marketing strategy. However, the lack of visible detailed company contact information and security policies on the homepage may be areas for improvement to enhance customer trust and compliance transparency.

Security posture

The website demonstrates a solid baseline security posture with HTTPS enabled and no visible exposure of sensitive data. The implementation of a cookie consent mechanism aligns with GDPR requirements. However, the absence of explicit security headers such as Content-Security-Policy and lack of published security or incident response policies represent gaps in security maturity. No vulnerabilities or suspicious elements were detected in the HTML content. The missing WHOIS data reduces the ability to fully verify domain legitimacy, which is a minor risk factor. Overall, the security posture is good but could be enhanced by publishing security policies and improving HTTP security headers.

Recommendations

  1. Implement and publish a comprehensive privacy policy and terms of service accessible from the homepage.
  2. Add explicit HTTP security headers including Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security.
  3. Provide clear contact information including security incident response contacts and data protection officer details.
  4. Improve WHOIS data transparency or ensure domain registration information is publicly accessible to enhance trust.
  5. Regularly audit and update third-party scripts and tracking tools to minimize security risks.

Technical notes

Notes

The website uses a modern technology stack including Google Tag Manager, Bing Ads, and SpeedCurve LUX for analytics and performance monitoring. It employs service workers (though unregistering them on load) and AMP client scripts, indicating efforts towards performance optimization. The site is mobile-optimized with responsive design and accessibility features such as ARIA attributes in search forms. SEO is supported by proper meta tags, canonical links, and structured navigation. Hosting provider and CMS are not explicitly identified from the HTML content. Performance is moderate with preloading of fonts and scripts. Technical risks are minimal but could be reduced by enhancing security headers and ensuring all third-party scripts are up to date.
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.
