Exxon Mobil Corporation · Energy · United States

Medium risk. 4 critical or high findings in GDPR outside view and SSL/TLS.

Security score

55/100

Risk levelMedium

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

Exxon Mobil Corporation operates as a leading global integrated energy company, providing a broad portfolio of energy, chemical, and lubricant products. The company is positioned as a major player in the energy sector with a strong focus on sustainability and innovation, including carbon capture and lower-emission technologies. The website reflects a mature enterprise with comprehensive content targeting investors, customers, and the general public. Technically, the site uses modern frameworks and is hosted on a reputable CDN, but lacks a valid SSL certificate, which is a critical security flaw. Security headers are well configured, but without HTTPS, the security posture is weak. Privacy compliance is well addressed with clear policies and cookie consent mechanisms. Overall, the site is professional and trustworthy but requires urgent remediation of SSL/TLS issues to ensure secure user interactions.

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

      No HTTPS encryption

      GDPR requires appropriate security measures for personal data

      What to do: Implement SSL/TLS certificate for HTTPS

    • High

      No Cookie Policy found

      GDPR requires clear information about cookie usage

      What to do: Add a dedicated cookie policy explaining cookie usage and purposes

    • 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.

    • Critical

      No HTTPS Encryption

      Website does not use HTTPS encryption, making all data transmission vulnerable to interception

      What to do: Implement SSL/TLS certificate and redirect all HTTP traffic to HTTPS

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 maintains a strong market position with a diversified business model spanning upstream, downstream, and chemical sectors. Its global brand portfolio includes Mobil, Esso, XTO, and Proxxima, reflecting extensive geographic and sectoral reach. The website supports investor relations, sustainability initiatives, and career opportunities, indicating a mature and transparent corporate governance structure. Partnerships and subsidiaries are well integrated, with multiple localized domains supporting regional operations. The business model emphasizes innovation in energy solutions and sustainability, aligning with global energy transition trends.

Security posture

While the website employs several security best practices such as strict content security policies, X-Frame-Options, and XSS protection headers, the absence of a valid SSL/TLS certificate severely undermines the security posture. No TLS protocols are enabled, and critical features like OCSP stapling and session resumption are missing. There is no visible vulnerability disclosure or incident response information, which could impact trust and compliance. The site should prioritize obtaining and deploying a valid SSL certificate and enabling modern TLS protocols to protect data in transit and improve overall security.

Recommendations

  1. Deploy a valid SSL/TLS certificate immediately to enable HTTPS across the site.
  2. Enable TLS 1.2 or TLS 1.3 protocols and disable insecure protocols.
  3. Implement OCSP stapling and session resumption to enhance security and performance.
  4. Publish a vulnerability disclosure policy and provide incident response contact information.
  5. Continue maintaining and updating privacy and cookie consent mechanisms to ensure compliance.
Technical notes

Notes

The website is built on ASP.NET technology and leverages Akamai CDN for hosting and content delivery. It integrates Google Tag Manager for analytics and OneTrust for cookie consent management. The site is mobile responsive and accessible, with good SEO practices including meta tags and Open Graph data. Performance metrics were not available, but the use of a CDN and lazy loading images suggests optimization efforts. The absence of SSL/TLS is a critical technical risk. The site structure is well organized with clear navigation and comprehensive content sections.
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.
