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

ROSSMANN.cz is the online presence of ROSSMANN, a large retail chain specializing in drugstore products in the Czech Republic. The website offers a broad assortment of quality goods at competitive prices, including current promotions, flyers, and customer contests. The site targets retail consumers in the Czech market and positions itself as a well-established player in the retail sector. Technically, the website employs modern JavaScript frameworks and libraries, including React components, Google Tag Manager, and Cookiebot for cookie consent management. The site is mobile-optimized and uses preloading techniques for fonts and images to enhance performance. Security-wise, HTTPS is enforced, and cookie consent is implemented, but no explicit security headers or privacy policy pages were detected in the provided content. The WHOIS data is missing, which reduces domain trustworthiness, but the website content and branding suggest a legitimate business. Overall, the site demonstrates good digital maturity with room for improvement in security and privacy 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

3 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 Strict-Transport-Security header

      Forces HTTPS connections

      What to do: Add "Strict-Transport-Security: max-age=31536000; includeSubDomains; preload"

      • CWE-319
      • OWASP A04:2025
      • ASVS V3.4.1
    • High

      Missing X-Frame-Options header

      Prevents clickjacking attacks

      What to do: Add "X-Frame-Options: DENY" or "X-Frame-Options: SAMEORIGIN"

    • 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';…

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

ROSSMANN operates as a major retail chain in the Czech Republic, focusing on drugstore and consumer goods. Its business model revolves around physical stores supported by an online platform that promotes sales and customer engagement through loyalty programs and marketing campaigns. The company leverages Google analytics and advertising tools to optimize marketing efforts and track user behavior extensively. The absence of WHOIS data and explicit contact information online suggests a need for improved transparency. The website's consistent branding and professional design support its market position as a trusted retailer. Strategic partnerships or subsidiaries were not identified in the provided data.

Security posture

The website enforces HTTPS and uses cookie consent mechanisms, indicating compliance with basic security and privacy standards. However, the lack of visible security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options is a gap that could expose the site to certain web-based attacks. No vulnerability disclosures, incident response contacts, or security policies were found, which limits the site's preparedness for security incidents. The missing WHOIS data also raises concerns about domain registration transparency. Overall, the security posture is moderate but could be significantly improved by implementing recommended headers, publishing security policies, and enhancing privacy disclosures.

Recommendations

  1. Implement comprehensive security headers (CSP, X-Frame-Options, X-Content-Type-Options) to enhance protection against common web attacks.
  2. Publish a clear and accessible privacy policy and terms of service pages to improve transparency and compliance.
  3. Provide explicit contact information including security incident response contacts and data protection officer details.
  4. Verify and update WHOIS domain registration information to improve domain trustworthiness and legitimacy.
  5. Regularly audit third-party scripts and tracking technologies to ensure compliance with privacy regulations and minimize user tracking.

Technical notes

Notes

The website uses a modern JavaScript-based front-end with React components and various UI libraries such as Select2 and Keen-slider. It leverages Google Tag Manager and Google Analytics for marketing and analytics purposes. Fonts and images are preloaded to optimize performance. The site is mobile responsive and designed with accessibility considerations, though explicit accessibility features were not fully verifiable from the provided content. No CMS or hosting provider information was detected. Performance is moderate, with potential for improvement through enhanced caching and security header implementation. The absence of visible forms in the provided snippet limits analysis of data collection practices.
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.
