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

BigMat.cz is a well-established European network of independent building material merchants, operating primarily in the Czech Republic with a large footprint of 81 stores locally and over 1000 stores across 7 European countries. The company targets both DIY enthusiasts and professional builders, offering a wide range of construction materials and related services including delivery and an e-commerce platform. The website is professionally designed, with good SEO and structured data implementation, supporting a positive user experience and clear navigation. Technically, the site uses modern JavaScript libraries and Google Tag Manager for analytics and marketing, with a cookie consent mechanism in place. However, explicit privacy policies and terms of service documents are not found, and security headers or incident response information are missing, indicating areas for improvement in compliance and security posture. Overall, the domain registration data aligns well with the business claims, supporting legitimacy and trustworthiness.

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

5 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 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

      Detected services: Google Analytics, Facebook, YouTube

      What to do: Document all third-party data sharing in your privacy policy

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

Business profile

BigMat.cz holds a strong market position as a major retailer in the building materials sector in the Czech Republic and Europe. Its business model revolves around a network of independent merchants, leveraging local presence and a centralized e-commerce platform. The company benefits from partnerships with numerous suppliers and brands, as evidenced by the extensive list of suppliers displayed on the site. The target customer segments include both individual consumers and professional contractors. The website's content and structure indicate ongoing efforts to expand product offerings and improve customer engagement through promotions and informational content. The presence of Google site verification and Facebook domain verification further supports the company's digital credibility.

Security posture

The website demonstrates a moderate security posture with HTTPS usage and cookie consent mechanisms implemented. Google Tag Manager is used with consent updates, indicating awareness of privacy compliance. However, the absence of visible security headers such as Content Security Policy, HSTS, and X-Frame-Options reduces the overall security robustness. No incident response or vulnerability disclosure information is provided, which could hinder timely handling of security issues. There are no indications of exposed sensitive data or vulnerable libraries in the analyzed content. The site would benefit from publishing a security policy, incident response contacts, and implementing additional security headers to enhance protection.

Recommendations

  1. Publish a comprehensive privacy policy and terms of service documents to improve legal compliance.
  2. Implement and publish a security policy and incident response contact information to enhance transparency and readiness.
  3. Add security headers such as Content Security Policy, HSTS, X-Frame-Options, and X-XSS-Protection to strengthen security posture.
  4. Improve accessibility features to meet higher standards and support all users.
  5. Regularly audit and update third-party libraries and scripts to avoid vulnerabilities.

Technical notes

Notes

The website is built on the ineShop CMS platform, utilizing modern JavaScript libraries including jQuery, Splide.js for sliders, and Fancybox for image display. Google Tag Manager and Google Analytics 4 are integrated for marketing and analytics purposes. The site uses asynchronous script loading and lazy loading for images, contributing to moderate performance. SEO is supported by meta tags, Open Graph tags, and JSON-LD structured data for organization and website schema. Mobile optimization is good, with responsive design elements. However, no explicit hosting provider information is found. The site could improve by adding more accessibility features and optimizing security headers.
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.
