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. 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. 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

Esso's website reflects a mature business model focused on retail fuel sales, loyalty incentives via PC Optimum™, and commercial fuel services including cardlock programs. The brand benefits from ExxonMobil's global presence and leverages partnerships and sponsorships to enhance market visibility. The digital platform supports customer engagement through mobile apps and social media channels, indicating a strategic approach to customer retention and brand loyalty. The presence of multiple localized domains and alternate language versions suggests a broad geographic and demographic reach. The company maintains a strong ecosystem of partners and subsidiaries, reinforcing its competitive advantage in the Canadian energy sector.

Security posture

The website exhibits a strong security posture with HTTPS enforced and comprehensive Content-Security-Policy headers restricting resource loading to trusted domains. The use of OneTrust for cookie consent and compliance indicates attention to privacy regulations such as GDPR. No exposed sensitive data or vulnerable libraries were detected in the HTML content. However, the absence of a publicly accessible security policy or incident response page limits transparency. No security.txt or vulnerability disclosure mechanisms were found, which could be improved to enhance trust and facilitate responsible vulnerability reporting. Overall, the site is secure but could benefit from increased security communication and formalized incident response disclosures.

Recommendations

  1. Publish a dedicated security policy page outlining security practices and compliance.
  2. Implement and publicize a vulnerability disclosure program or security.txt file.
  3. Provide clear contact information for data protection officer or security incidents.
  4. Regularly review and audit third-party scripts to minimize supply chain risks.
  5. Consider enabling DNSSEC to enhance domain name system security.

Technical notes

Notes

The website is built on the Sitecore CMS platform and hosted primarily on AWS infrastructure, utilizing Cloudflare CDN services for performance and security. It employs a modern tech stack including JavaScript frameworks, YouTube iframe API, and integrates marketing and analytics tools such as Google Tag Manager, AppDynamics, and OneTrust for consent management. The site demonstrates excellent mobile optimization, accessibility, and SEO practices. Performance is optimized with preloading fonts and asynchronous script loading. The extensive Content-Security-Policy mitigates cross-site scripting risks. Technical debt appears minimal, and the infrastructure supports scalability and reliability for a large enterprise brand.
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.
