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

Santos is a large, global energy company primarily operating in Australia and nearby regions such as Papua New Guinea, Timor-Leste, and the United States. The company focuses on providing reliable and affordable energy with a strategic emphasis on sustainability and lower carbon energy solutions. Their business model includes upstream projects, producing assets, and midstream energy solutions, targeting investors, communities, and partners. The website reflects a professional and consistent brand with comprehensive investor and sustainability information. Technically, the website is built on WordPress with modern technologies including jQuery, Google Analytics, Google Tag Manager, and Vimeo for multimedia content. The site is mobile optimized, accessible, and SEO friendly, though performance is moderate. Security posture is good with HTTPS enforced and no visible sensitive data exposure, but lacks some security headers and explicit incident response information. The WHOIS data is unavailable or privacy protected, which slightly reduces trust but is not uncommon for large corporations. No direct contact emails or phone numbers were found on the homepage, but social media presence is strong. Privacy policy and terms of service are present and comprehensive, though no cookie consent mechanism was detected. Overall, the site is professional and trustworthy with minor improvements recommended in security headers, cookie consent, and transparency of registrant data to enhance compliance and trust.

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

6 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. GDPR outside view

    These are the privacy signals visitors and data protection authorities look for under GDPR.

    • 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

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

Santos holds a strong market position as a global energy provider with a focus on sustainability and community engagement. Their business model leverages upstream and midstream energy assets and solutions, targeting a broad audience including investors and local communities. The company demonstrates growth through investments in climate transition action plans and community partnerships. Their digital presence supports investor relations and corporate governance transparency. Partnerships with social media platforms and use of advanced analytics indicate a mature digital marketing strategy. The lack of visible direct contact information suggests a controlled communication approach, typical for large enterprises.

Security posture

The website demonstrates a mature security posture with HTTPS enforced and no exposed sensitive information in the HTML content. Use of Google Tag Manager and asynchronous loading of analytics scripts reduces performance impact and potential security risks. However, the absence of key security headers such as Content-Security-Policy and X-Frame-Options is a gap. No explicit security policies or incident response contacts are published, which could hinder rapid response to security incidents. The lack of a vulnerability disclosure or security.txt file limits transparency for security researchers. Overall, the security posture is good but could be improved with enhanced headers, explicit policies, and incident response information.

Recommendations

  1. Implement comprehensive security headers including Content-Security-Policy, X-Content-Type-Options, and X-Frame-Options to mitigate common web attacks.
  2. Add a cookie consent banner or mechanism to comply fully with GDPR and other privacy regulations.
  3. Publish a clear security policy and incident response contact information on the website to improve transparency and readiness.
  4. Consider adding a vulnerability disclosure policy or security.txt file to encourage responsible reporting of security issues.
  5. Enhance WHOIS transparency if possible or provide corporate registration details on the website to improve trustworthiness.

Technical notes

Notes

The website is built on a WordPress CMS platform using modern JavaScript libraries such as jQuery and integrates multimedia content via Vimeo. It employs Google Analytics and Google Tag Manager for tracking and marketing purposes, alongside Sentry for error monitoring. The site is mobile responsive and optimized for accessibility and SEO, with proper meta tags and structured data (JSON-LD) for organization and website schema. Performance is moderate, likely due to rich multimedia content and external script dependencies. There is no indication of outdated or vulnerable libraries in the HTML content. Hosting provider details are not explicitly identified. Overall, the technical infrastructure is solid with room for performance optimization.
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.
