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

DATART, operated by HP Tronic s.r.o., is a leading electronics retailer in the Czech Republic offering a wide range of consumer electronics products through its online platform and physical stores. The website provides extensive product categories including TVs, audio equipment, mobile phones, smart home devices, and more, targeting general consumers in the Czech market. The business model focuses on e-commerce complemented by delivery and installation services, positioning DATART as a trusted electronics specialist in the region. Technically, the website employs modern web technologies including Google Tag Manager, Bing Ads, and performance monitoring tools like SpeedCurve LUX. It is well optimized for mobile devices and accessibility, with a professional design and clear navigation structure. Security-wise, the site enforces HTTPS and includes a cookie consent mechanism, but lacks explicit security headers and published privacy or terms of service pages, which are areas for improvement. The absence of WHOIS data limits domain trust analysis, but the website's professional presentation and business indicators suggest legitimacy. Overall, DATART demonstrates a mature digital presence with room to enhance privacy and security transparency.

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

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

DATART operates in the retail sector specializing in consumer electronics, serving the Czech Republic market. Its competitive advantage lies in a comprehensive product catalog, strong brand presence, and value-added services such as free installation of large appliances. The business model is primarily e-commerce with physical store support, targeting a broad consumer base. Partnerships, such as with Euronics Group, enhance market reach and credibility. The website's extensive categorization and product segmentation indicate a well-developed marketing strategy aimed at diverse customer segments. Growth indicators include active marketing campaigns and integration of modern analytics and advertising tools. Strategic observations suggest focusing on enhancing privacy compliance and security policies to strengthen customer trust and regulatory adherence.

Security posture

The website maintains a good security baseline with HTTPS enforced and no visible exposure of sensitive data in the HTML content. The presence of a cookie consent mechanism aligns with GDPR requirements, though no explicit privacy policy or terms of service pages were found, indicating compliance gaps. Security headers such as Content-Security-Policy and X-Frame-Options are not detected, representing an opportunity to harden security posture. No vulnerability disclosures or incident response contacts are published, which could impact incident handling readiness. Overall, the security maturity is moderate, with strengths in encryption and tracking transparency but weaknesses in policy publication and header implementation. Addressing these gaps would improve compliance with GDPR and NIS2 directives and enhance customer confidence.

Recommendations

  1. Publish a comprehensive privacy policy and terms of service pages prominently linked on the website.
  2. Implement and configure security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  3. Provide clear contact information for security incidents, including an incident response or abuse email address.
  4. Consider publishing a security.txt file to facilitate vulnerability disclosure and improve transparency.
  5. Regularly audit third-party scripts and tracking tools to ensure no vulnerable libraries are included.

Technical notes

Notes

The website uses a modern JavaScript-based frontend with asynchronous loading of analytics and advertising scripts. It leverages Google Tag Manager for flexible marketing and tracking integration, Bing Ads for advertising, and SpeedCurve LUX for performance monitoring. The site is optimized for mobile devices and accessibility, with semantic HTML elements and ARIA attributes for navigation aids. Service workers are present but unregistered on load, possibly to avoid caching issues. The site lacks explicit CMS identification and hosting provider details. Performance is moderate, with potential improvements in loading speed by optimizing third-party scripts. SEO is supported by proper meta tags, canonical links, and structured navigation. Overall, the technical infrastructure supports a robust e-commerce platform but could benefit from enhanced security configurations and privacy transparency.
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.
