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

Esso Card is a UK-based provider specializing in fuel cards for businesses, fleets, and hauliers across the UK and Europe. The company positions itself as a leading provider offering fuel savings and convenient online application processes. The website is professionally designed using WordPress with modern technologies such as jQuery, Bootstrap, and Font Awesome, and is optimized for SEO with Yoast plugin integration. However, the lack of WHOIS data raises concerns about domain registration legitimacy. Security posture is moderate with HTTPS likely enabled but missing explicit security headers and policies. Privacy and cookie policies are not evident, which may impact compliance and user trust. Overall, the site is business-focused, safe, and functional but would benefit from enhanced transparency and security measures.

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

7 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';…

  2. Email security

    SPF, DKIM and DMARC stop others sending email that looks like it comes from your domain, a common route to phishing and invoice fraud.

    • High

      No SPF record found

      SPF helps prevent email spoofing

      What to do: Add SPF record: "v=spf1 include:_spf.yourmailprovider.com ~all"

  3. 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

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

The company targets small to medium-sized businesses, fleets, and hauliers in the energy and transportation sectors, offering fuel cards as their primary service. Their business model revolves around providing cost-saving fuel solutions with an online application process. The presence of partner domains like wexdrive.com suggests integration with fuel management platforms. The website content and branding are consistent and professional, indicating a stable market position in the UK and European fuel card market. However, the absence of detailed company registration and contact information limits full business credibility assessment.

Security posture

The website demonstrates a basic to moderate security maturity level. HTTPS is presumably enabled, but no security headers such as Content Security Policy, HSTS, or X-Frame-Options were detected in the provided content. There is no visible privacy policy, cookie consent mechanism, or incident response contact information, which are critical for GDPR compliance and user trust. No vulnerabilities or exposed sensitive data were identified in the HTML content. The lack of WHOIS data and domain registration details introduces a risk factor. Overall, the security posture requires improvements in transparency, policy publication, and technical security controls.

Recommendations

  1. Implement and publish comprehensive privacy and cookie policies with GDPR compliance details.
  2. Add security headers including CSP, HSTS, and X-Frame-Options to enhance protection against common web attacks.
  3. Publish clear contact information including company emails and phone numbers for customer and incident response.
  4. Verify and update WHOIS domain registration information to improve trust and legitimacy.
  5. Establish a vulnerability disclosure policy and incident response contact channels to demonstrate security readiness.

Technical notes

Notes

The website is built on WordPress CMS with a modern tech stack including jQuery, Bootstrap grid system, Font Awesome icons, and Yoast SEO plugin for optimization. The site loads multiple CSS and JS resources asynchronously and uses Google Tag Manager for analytics and marketing tracking. Mobile optimization and SEO appear good, but accessibility features are basic. Performance is moderate with potential for improvement by optimizing resource loading and caching. Hosting provider details are not evident from the content. Technical debt is low but security-related technical enhancements are recommended.
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.
