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

ExxonMobil operates a comprehensive and professionally designed website focused on retail and commercial fuel products, including gasoline, diesel, and related rewards programs. The company is a global leader in the energy sector, targeting both general consumers and commercial clients with a broad portfolio of services. The website demonstrates a mature digital infrastructure leveraging modern technologies such as AWS hosting, Sitecore CMS, and advanced analytics and marketing tools. Security posture is strong with HTTPS enforcement, robust content security policies, and cookie consent mechanisms. However, explicit security policies and incident response information are not prominently published, representing an area for improvement. Overall, the website reflects a high level of professionalism, trustworthiness, and compliance with privacy regulations.

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. 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 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

ExxonMobil maintains a dominant market position in the energy sector with a diversified business model encompassing fuel retail, commercial fuel delivery, and loyalty programs. The website supports multiple global brands and subsidiaries, including Mobil and Esso, indicating a broad partnership ecosystem. The company targets a wide audience from individual consumers to large commercial fleets. The digital presence is optimized for performance and mobile use, supporting growth and customer engagement. Strategic partnerships and extensive use of marketing and analytics tools suggest a data-driven approach to customer acquisition and retention.

Security posture

The website exhibits a strong security posture with HTTPS, comprehensive Content Security Policy headers, and cookie consent management aligned with GDPR requirements. No critical vulnerabilities or exposed sensitive data were detected in the HTML content. However, the absence of a published security policy or incident response contact details limits transparency. The WHOIS data is incomplete, likely due to privacy protection, which is common for large enterprises but should be monitored. Recommendations include publishing a security.txt file and enhancing public security documentation to improve trust and incident handling readiness.

Recommendations

  1. Publish a dedicated security policy page outlining security frameworks and practices.
  2. Add a security.txt file to facilitate responsible vulnerability disclosure.
  3. Provide clear contact information for the Data Protection Officer or security team.
  4. Maintain and update WHOIS information transparency where possible to enhance trust.
  5. Continue monitoring third-party scripts and analytics for privacy compliance and performance impact.

Technical notes

Notes

The website is built on a modern technology stack including Sitecore CMS, AWS hosting, and integrates multiple third-party services for analytics, marketing, and user engagement. Performance is optimized with CSS and JS minification, preloading fonts, and CDN usage. Mobile optimization and accessibility features are well implemented. The extensive Content Security Policy restricts resource loading to trusted domains, enhancing security. The use of Google Tag Manager and OneTrust for consent management indicates a mature approach to privacy and data governance. Opportunities exist to further document technical security controls and incident response capabilities.
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.
