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

Mironet.cz is a well-established Czech online retail company specializing in a wide range of products including mobile phones, tablets, computers, components, networking equipment, gaming, accessories, electronics, toys, hobby, household, and garden items. The website demonstrates a professional e-commerce platform with a broad product catalog and multiple customer engagement features such as PC configurator and pickup points. Technically, the site uses modern JavaScript libraries including Swiper.js for carousels, Google Tag Manager, Microsoft Clarity, and Bing UET for analytics and tracking, with HTTPS and security headers properly configured. However, the absence of a cookie consent mechanism and lack of publicly available WHOIS data present compliance and trust challenges. Overall, the site maintains a good security posture but could improve privacy compliance and 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.

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

Mironet.cz operates in the competitive Czech e-commerce market with a focus on technology and consumer electronics. Its business model is retail-oriented, targeting general consumers seeking a variety of electronic and household products. The company leverages multiple marketing and analytics tools to optimize customer engagement and sales. The presence of social login options and detailed contact information supports customer trust and service. The lack of WHOIS data is a notable gap but does not negate the company's apparent market presence. The company appears to be large in size with consistent branding and a professional online presence.

Security posture

The website employs HTTPS with a good SSL configuration and security headers such as Content-Security-Policy to upgrade insecure requests. Login forms support multiple authentication methods including social logins, enhancing security and user convenience. No exposed sensitive data or vulnerable libraries were detected in the HTML content. However, the absence of a published security policy, incident response contacts, and vulnerability disclosure mechanisms limits transparency and preparedness. Privacy compliance is partial, with no visible cookie consent banner, which may expose the company to regulatory risks under GDPR. Overall, the security posture is solid but could be enhanced by formalizing policies and improving privacy controls.

Recommendations

  1. Implement a comprehensive cookie consent banner to ensure GDPR compliance and user transparency.
  2. Publish a clear security policy and incident response contact information on the website.
  3. Consider adding a vulnerability disclosure policy and security.txt file to encourage responsible reporting.
  4. Enhance accessibility features to improve compliance and user experience for all visitors.
  5. Verify and publish domain WHOIS information to improve trust and legitimacy perception.

Technical notes

Notes

The website uses a modern JavaScript-based front end with libraries such as Swiper.js for interactive carousels and Google Tag Manager for analytics management. It integrates multiple tracking services including Microsoft Clarity and Bing UET, indicating a mature approach to user behavior analysis. The site is mobile-optimized with responsive design and uses SVG icons for scalability. Performance appears moderate with some lazy loading of images. No CMS or hosting provider details were detected from the HTML content. The site could benefit from enhanced accessibility features and improved privacy mechanisms. Overall, the technical infrastructure supports a robust e-commerce experience but has room for modernization in privacy and accessibility.
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.
