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

Shell Česká republika operates a comprehensive digital presence focused on fuel retail, electric vehicle charging, and loyalty programs under the Shell brand. The website targets both general consumers and corporate clients, offering services such as fuel stations, Shell ClubSmart loyalty benefits, car wash, and Shell Café. The site reflects a strong market position as a leading energy provider in the Czech Republic, supported by consistent branding and professional content. Technically, the website is built on Adobe Experience Manager, leveraging modern web technologies including ES modules, CSS variables, and responsive design. The site is mobile-optimized and accessible, with good SEO practices and performance. Privacy and cookie policies are clearly presented with consent mechanisms, indicating compliance with GDPR. Security posture is solid with HTTPS enforced and secure login portals, though explicit security headers and vulnerability disclosure mechanisms are absent. No WHOIS data was retrievable, which limits domain trust analysis but the website content and official social media presence strongly support legitimacy. Overall, the website is professional, secure, and compliant, with recommendations to enhance security headers and publish vulnerability disclosure information to further strengthen trust and security posture.

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

2 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 SSL Key Length

      SSL certificate uses 256-bit key, which is considered weak

      What to do: Use at least 2048-bit RSA or 256-bit ECC key

      • CWE-326
      • OWASP A04:2025
      • Mozilla TLS: Mozilla Server Side TLS 6.0 intermediate: rsa_key_size 2048

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

Shell Česká republika is positioned as a major player in the Czech energy and transportation sectors, providing fuel, lubricants, and electric vehicle charging services. The business model combines retail fuel sales with value-added services like loyalty programs and corporate fuel cards. The company leverages partnerships and a global brand (Shell plc) to maintain competitive advantages. The website supports customer engagement through digital tools and social media, indicating a mature digital marketing strategy. Growth indicators include promotion of electric mobility and digital loyalty benefits. The absence of WHOIS data is unusual but does not detract from the strong brand presence and market position.

Security posture

The website demonstrates a mature security posture with HTTPS enforced and secure login mechanisms. Privacy and cookie policies with consent mechanisms indicate GDPR compliance. However, the absence of explicit security headers such as Content-Security-Policy and lack of a published security.txt or vulnerability disclosure page represent gaps. No exposed vulnerabilities or sensitive data were detected. Incident response contact information is not explicitly provided, which could hinder rapid response to security incidents. Overall, the security maturity is good but could be improved by adopting additional best practices and transparency measures.

Recommendations

  1. Implement and enforce security headers including Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security.
  2. Publish a security.txt file to facilitate vulnerability reporting and improve transparency.
  3. Provide explicit incident response contact information on the website.
  4. Enhance WHOIS data availability or transparency to improve domain trustworthiness.
  5. Continue to monitor and update privacy and cookie consent mechanisms to maintain GDPR compliance.

Technical notes

Notes

The website is built on Adobe Experience Manager, a robust enterprise CMS platform, using modern front-end technologies such as ES modules and CSS variables. The site is responsive and optimized for mobile devices, with good accessibility features. Performance is moderate, with potential for improvement in load times. The use of SVG logos and icons ensures scalability and crisp visuals. Integration with Adobe Launch and Evidon indicates advanced marketing and privacy management capabilities. No legacy or vulnerable libraries were detected. Technical risks are minimal but could be reduced by improving security header implementation.
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.
