No critical vulnerabilities or suspicious indicators were found. Overall, the website reflects a mature digital presence consistent with a large multinational energy retailer.

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 Norway holds a strong market position in the energy retail sector, providing essential services to motorists and travelers. The business model focuses on retail fuel sales complemented by value-added services like EV charging and convenience offerings. The website supports brand consistency with ExxonMobil and integrates advanced marketing tools to engage customers. The presence of multiple external domains related to ExxonMobil and marketing partners indicates a robust partnership ecosystem. Growth indicators include digital tools for station location and customer engagement. The company targets a broad consumer base in Norway, emphasizing accessibility and service quality.

Security posture

The website demonstrates a high level of security maturity with HTTPS and strict Content Security Policy headers. No exposed sensitive data or vulnerable libraries were detected in the analyzed content. The use of cookie consent and privacy policies aligns with GDPR requirements. However, the absence of a public security policy, incident response contacts, or vulnerability disclosure mechanisms suggests areas for improvement in transparency and incident readiness. The integration of multiple third-party scripts necessitates ongoing security audits to mitigate supply chain risks. Overall, the security posture is strong but could benefit from enhanced policy disclosures.

Recommendations

  1. Publish a dedicated security policy page outlining security practices and commitments.
  2. Implement a vulnerability disclosure program or security.txt file to encourage responsible reporting.
  3. Provide clear incident response contact information for security issues.
  4. Regularly review and update third-party scripts and dependencies to prevent vulnerabilities.
  5. Enhance transparency around data retention policies and user privacy controls.

Technical notes

Notes

The website is built on a modern technology stack including Sitecore CMS and hosted on AWS, ensuring scalability and reliability. It uses Bootstrap for responsive design and integrates multiple mapping services (Bing, Yandex, Baidu) for location features. Performance is moderate with asynchronous loading of scripts and CSS. Accessibility features such as skip links and ARIA roles are present, supporting usability for diverse users. SEO is supported by comprehensive meta tags and Open Graph data. The technical implementation reflects a well-maintained enterprise-grade website with opportunities to optimize load times and reduce third-party script dependencies.
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.
