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

Renault Česká republika operates as the official local website for Renault in the Czech Republic, offering a comprehensive range of new, used, and commercial vehicles. The site targets consumers interested in Renault's automotive products, including electric and hybrid models. The business is positioned as a major automotive brand with a strong market presence supported by the global Renault Group. The website provides detailed vehicle information, configuration options, and promotional content tailored to the Czech market. Technically, the website employs a modern React framework with optimized images and responsive design, ensuring excellent mobile usability and good SEO practices. Integration with Google Analytics and Tag Manager indicates a mature digital marketing and analytics setup. Cookie consent is managed via OneTrust, reflecting compliance with GDPR requirements. From a security perspective, the site uses HTTPS and cookie consent mechanisms but lacks explicit security headers and publicly available security policies or incident response contacts. The absence of WHOIS data limits domain registration trust analysis, but the professional presentation and official branding strongly indicate legitimacy. Overall, the site demonstrates a solid security posture with room for improvement in transparency and security header implementation. The overall risk is low, with recommendations to enhance security headers, publish security policies, and provide clear contact information for security incidents to further strengthen trust and compliance.

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

4 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

      Third-party services without privacy policy

      Detected services: Google Analytics, Facebook, LinkedIn, YouTube

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

  2. 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 X-Frame-Options header

      Prevents clickjacking attacks

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

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

Renault Česká republika is a key player in the automotive sector within the Czech Republic, leveraging the global Renault brand. Its business model focuses on direct vehicle sales, including new electric and hybrid cars, used vehicles, and commercial vehicles. The website supports customer engagement through vehicle configurators and detailed product information. The company likely generates revenue through vehicle sales and associated services. The digital presence is well-integrated with marketing and analytics tools, indicating a strategic approach to customer acquisition and retention. Partnerships with global Renault infrastructure and local dealerships are implied but not explicitly detailed in the provided data.

Security posture

The website demonstrates a moderate to good security maturity level. HTTPS is enforced, and cookie consent is implemented via a reputable third-party solution (OneTrust), supporting GDPR compliance. However, the lack of visible security headers such as Content Security Policy (CSP), HTTP Strict Transport Security (HSTS), and X-Frame-Options reduces the overall security posture. No explicit security policy or incident response information is publicly available, which could hinder effective communication during security events. No vulnerabilities or exposed sensitive data were detected in the analyzed content. The site would benefit from enhanced security transparency and technical hardening.

Recommendations

  1. Implement and publish comprehensive security headers including CSP, HSTS, and X-Frame-Options.
  2. Provide a publicly accessible security policy and incident response contact information.
  3. Enhance transparency by publishing vulnerability disclosure or security.txt files.
  4. Include clear company contact information such as official emails and phone numbers on the website.
  5. Regularly audit third-party scripts and tracking tools to ensure compliance and minimize privacy risks.

Technical notes

Notes

The website is built using React, leveraging modern web technologies such as WebP images and SVG icons for performance and scalability. It integrates with Google Tag Manager and Google Analytics for marketing and analytics purposes. The presence of OneTrust scripts indicates a mature approach to privacy compliance. The site is mobile-optimized with responsive design and good accessibility features. Performance is moderate, likely due to the rich media content and client-side rendering. No CMS or hosting provider details were explicitly identified. Opportunities exist to improve technical SEO and security header implementation to reduce technical debt and enhance resilience.
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.
