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

GS1 Czech Republic operates as the sole licensed authority for assigning GTIN and barcode identification numbers within the Czech Republic, serving businesses that require standardized product identification for retail, healthcare, and e-commerce sectors. The website presents a professional and comprehensive digital presence, offering services such as training, data synchronization, and product management tools like GS1 Activate. The organization maintains strong branding consistency and trust indicators, including accredited partners and official GS1 affiliations. Technically, the website is built on WordPress with modern technologies including jQuery, Google Tag Manager, and CookieHub for cookie consent management. The site is optimized for performance, mobile responsiveness, and SEO, with structured data enhancing search engine understanding. Security measures include HTTPS, Google reCAPTCHA, and secure AJAX interactions, though explicit security headers and incident response policies are not publicly documented. The security posture is solid with no evident vulnerabilities or exposed sensitive data. Privacy compliance is well addressed with a comprehensive privacy policy, cookie consent mechanisms, and GDPR adherence. WHOIS data is unavailable, likely due to privacy protection, but the website content and affiliations strongly support legitimacy. Overall, the site demonstrates a mature digital infrastructure and trustworthy business model, with recommendations to enhance security headers, publish incident response information, and consider a security.txt file for vulnerability disclosures.

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. GDPR outside view

    These are the privacy signals visitors and data protection authorities look for under GDPR.

    • 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

  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.

    • High

      Weak Protocols Supported

      Server supports weak protocols: TLSv1.1

      What to do: Disable TLS 1.0, TLS 1.1, and all SSL versions

      • CWE-327
      • OWASP A04:2025
      • ASVS V12.1.1

  3. Network security

    Services reachable from the internet are the first thing attackers probe. Anything open that does not need to be should be closed.

    • High

      High-Risk Service Exposed: FTP

      Port 21 (FTP) is publicly accessible - FTP - Often unencrypted file transfer

      What to do: Consider restricting access to FTP or implementing strong authentication

      • NIS2 21(2)(e)
      • IR 2024/2690 6.7.2(f): Implementing Regulation (EU) 2024/2690, Annex point 6.7.2(f): Network security
      • NIST CM-7: NIST SP 800-53 Rev. 5 CM-7: Least Functionality
      • NIST SC-7: NIST SP 800-53 Rev. 5 SC-7: Boundary Protection

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

GS1 Czech Republic holds a unique market position as the exclusive GS1 registration authority in the Czech Republic, providing essential services for product identification and supply chain standardization. Their business model focuses on licensing GTIN numbers, offering training, consulting, and digital tools to facilitate compliance and data sharing. The target customers are businesses in retail, healthcare, logistics, and online marketplaces. The organization benefits from strong partnerships with global and regional GS1 entities and maintains a medium-sized operational scale. Growth indicators include active training schedules and digital tool adoption. The company leverages a trusted brand and maintains a professional online presence to support its market leadership.

Security posture

The website exhibits a good security maturity level with HTTPS enforced, integration of Google reCAPTCHA to prevent automated abuse, and a detailed cookie consent mechanism supporting GDPR compliance. No critical vulnerabilities or exposed sensitive information were detected in the HTML content. However, the absence of explicit security headers such as X-Frame-Options and X-Content-Type-Options suggests room for improvement. The lack of published security policies or incident response contacts limits transparency. Overall, the security posture is strong but could be enhanced by formalizing security documentation and adding recommended HTTP headers.

Recommendations

  1. Implement and enforce additional HTTP security headers including X-Frame-Options and X-Content-Type-Options to mitigate clickjacking and MIME sniffing risks.
  2. Publish a security policy and incident response plan on the website to improve transparency and readiness.
  3. Add a security.txt file to facilitate responsible vulnerability disclosure and communication.
  4. Regularly audit and update WordPress core, themes, and plugins to minimize exposure to known vulnerabilities.
  5. Provide contact information for a Data Protection Officer or privacy contact to enhance GDPR compliance and user trust.

It integrates Google Tag Manager and Google Analytics for tracking and marketing purposes, alongside CookieHub for cookie consent management. The site uses WP Rocket for performance optimization, including lazy loading of images and scripts. Structured data via JSON-LD and Open Graph tags are implemented for SEO enhancement. The site is mobile-optimized with responsive design and accessibility considerations. No major technical debt or outdated technologies were detected, indicating a well-maintained infrastructure with good performance and SEO 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.
