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

Alumina Limited is an energy sector company specializing in alumina production. The website content is minimal and primarily serves to inform visitors that Alumina Limited was acquired by Alcoa Corporation as of August 1, 2024, directing users to Alcoa.com for further information. The digital presence is limited, with no detailed corporate information, contact details, or policies available on the homepage. Technically, the website uses basic HTML and CSS with no detected advanced frameworks or analytics. Security posture is weak due to lack of visible security headers, privacy policies, and WHOIS data. The domain WHOIS information is missing, which raises concerns about domain legitimacy and registration status. Overall, the website is accessible but lacks depth and comprehensive corporate digital infrastructure.

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

8 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 Privacy Policy found

      GDPR requires a clear and accessible privacy policy

      What to do: Add a comprehensive privacy policy page and link to it prominently

    • 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

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 business operates in the energy sector with a focus on alumina production. The acquisition by Alcoa Corporation positions Alumina Limited as a subsidiary, likely integrated into a larger corporate structure. The website's minimal content and lack of contact or policy information suggest a low emphasis on direct customer engagement or digital marketing. The primary audience appears to be investors and industry stakeholders seeking corporate updates. The absence of detailed business data and certifications limits insight into operational scale or competitive advantages. The partnership with Alcoa Corporation is the key strategic relationship identified.

Security posture

The website exhibits a low security maturity level. There are no detected security headers or SSL configuration details in the provided data. The absence of privacy and cookie policies indicates non-compliance with common data protection regulations such as GDPR. No incident response or vulnerability disclosure information is present. The missing WHOIS data further undermines trust and raises potential risks related to domain ownership transparency. The security score is low, and the site would benefit from implementing HTTPS, security headers, and clear privacy documentation to improve its security posture and compliance.

Recommendations

  1. Implement HTTPS with a valid SSL certificate to secure communications.
  2. Publish comprehensive privacy and cookie policies to comply with data protection regulations.
  3. Add contact information and incident response details to improve transparency and trust.
  4. Enhance website content with detailed corporate information and navigation to improve user experience.
  5. Obtain and publish WHOIS data or ensure domain registration information is accurate and accessible.

Technical notes

Notes

The website is built with basic HTML and CSS without detectable use of modern frameworks or CMS platforms. There is no evidence of JavaScript libraries, analytics tools, or tracking technologies in the provided HTML snippet. Performance and mobile optimization appear basic but functional. SEO optimization is minimal, with only canonical and Open Graph meta tags present. The lack of security headers and absence of HTTPS information suggest technical debt in security implementation. The site would benefit from modernization including responsive design improvements, enhanced SEO, and integration of security best practices.
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.
