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

7 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

Ternium holds a strong market position as a regional leader in steel manufacturing, targeting industrial clients across Latin America and the USA. The business model focuses on manufacturing and supplying steel products tailored to customer needs, supported by digital platforms like Ternium Activo for client services. The company maintains a robust partnership and subsidiary network across multiple countries, enhancing its regional footprint. The presence of investor relations and sustainability reporting indicates transparency and corporate governance maturity. Growth is supported by investments in environmental projects and innovation initiatives such as Industry 4.0.

Security posture

The website employs HTTPS with good SSL configuration and integrates security monitoring via Microsoft Application Insights. No critical vulnerabilities or exposed sensitive data were detected in the HTML content. However, the absence of explicit security headers (e.g., CSP, HSTS) and lack of publicly available security policies or incident response contacts represent areas for improvement. No vulnerability disclosure or security.txt files were found, which could enhance transparency and trust. Overall, the security posture is solid but could benefit from additional best practices and public documentation.

Recommendations

  1. Implement and enforce security headers such as Content Security Policy (CSP), HTTP Strict Transport Security (HSTS), and X-Frame-Options to enhance protection against common web attacks.
  2. Publish a dedicated security policy and incident response information on the website to improve transparency and preparedness.
  3. Establish a vulnerability disclosure program or publish a security.txt file to facilitate responsible reporting of security issues.
  4. Provide clear security contact channels (e.g., security@ or abuse@ email addresses) to enable direct communication for security concerns.
  5. Continue investing in privacy compliance and regularly update cookie and data protection policies to maintain GDPR and other regulatory adherence.

Technical notes

Notes

The website is built with modern web standards including HTML5, CSS3, and SVG graphics, and leverages popular analytics and monitoring tools such as Google Tag Manager and Microsoft Application Insights. The site is well-structured with good SEO metadata and multilingual support. Performance is moderate with multimedia content such as videos and images optimized for user experience. Mobile optimization and accessibility are rated good, supporting a broad user base. No CMS or hosting provider details were explicitly detected. Technical risks are minimal, but adding security headers and improving incident response visibility would strengthen the overall technical posture.
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.
