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. 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
    • 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 UK holds a significant position in the UK energy and transportation sectors, offering a diversified business model that includes fuel retail, engine oils, electric vehicle charging infrastructure, and loyalty programs. The company targets both general consumers and business customers, emphasizing convenience and rewards. Its partnership ecosystem includes digital platforms for app-based rewards and EV charging subscriptions. The website content and structure indicate a mature digital presence with strategic use of analytics and marketing tools. Growth indicators include enhanced loyalty rewards and EV charging subscription services, reflecting adaptation to evolving energy markets and customer preferences.

Security posture

The website demonstrates a mature security posture with enforced HTTPS, comprehensive security headers, and privacy compliance aligned with GDPR. Tracking and analytics scripts are managed with user consent mechanisms. No exposed sensitive data or vulnerable libraries were identified in the HTML content. However, the absence of explicit incident response or security policy pages suggests room for improvement in transparency and readiness communication. Overall, the security culture appears strong, but enhancing visibility of security contacts and incident response procedures would benefit trust and compliance.

Recommendations

  1. Enhance visibility and accessibility of security policy and incident response contact information on the website.
  2. Regularly audit and update third-party scripts to mitigate potential vulnerabilities and privacy risks.
  3. Implement and clearly communicate a vulnerability disclosure program or security.txt file to encourage responsible reporting.
  4. Ensure all forms include anti-CSRF tokens and secure input validation to prevent injection attacks.
  5. Maintain ongoing compliance monitoring for GDPR and other relevant data protection regulations.

Technical notes

Notes

The website is built on Adobe Experience Manager CMS, utilizing modern JavaScript modules, SVG graphics, and CSS variables for styling. Performance monitoring is implemented via Boomerang, and user tracking is managed through Kochava with consent mechanisms. The site is mobile-optimized and accessible, with good SEO practices including meta tags and Open Graph data. Hosting details are not explicitly disclosed, but the presence of Akamai CDN and Azure-hosted chatbot components indicate a robust infrastructure. Technical risks are minimal, with no visible outdated or vulnerable libraries. Opportunities exist to improve incident response readiness and security transparency.
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.
