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

3 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 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. 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 SSL Key Length

      SSL certificate uses 256-bit key, which is considered weak

      What to do: Use at least 2048-bit RSA or 256-bit ECC key

      • CWE-326
      • OWASP A04:2025
      • Mozilla TLS: Mozilla Server Side TLS 6.0 intermediate: rsa_key_size 2048

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

SCG's diversified business model spans multiple sectors including cement production, chemicals, packaging, and clean energy. The company targets investors, partners, and customers interested in sustainable industrial solutions. Their market position is strong in Thailand and ASEAN, supported by subsidiaries like CPAC and SCG Chemicals. The website highlights their commitment to ESG and innovation, signaling strategic focus on green technologies and circular economy. Investor relations transparency and corporate governance disclosures enhance credibility. The presence of regional partner sites and foundations indicates a broad ecosystem. SCG's business intelligence suggests a well-established conglomerate with growth driven by sustainability and innovation.

Security posture

The website enforces HTTPS with strong SSL configuration and includes key security headers such as Content-Security-Policy and X-Frame-Options. Cookie consent is managed via OneTrust, indicating compliance with privacy regulations. No exposed sensitive data or vulnerable libraries were detected in the HTML content. However, the absence of a public security.txt or vulnerability disclosure page limits transparency in incident response readiness. No direct security contact emails were found. Overall, the security posture is robust for a corporate site, but could be improved by publishing explicit security policies and incident response contacts.

Recommendations

  1. Publish a security.txt file or vulnerability disclosure policy to encourage responsible reporting.
  2. Add explicit incident response contact information for security issues.
  3. Regularly audit and update third-party scripts and dependencies to mitigate vulnerabilities.
  4. Enhance transparency around security frameworks and certifications on the website.
  5. Continue monitoring and improving privacy compliance as regulations evolve.

Notes

The website is built on a modern React/Next.js framework, leveraging Swiper.js for sliders and Bootstrap for responsive design. It uses OneTrust for cookie consent and Google Tag Manager for analytics and tracking. The site is mobile-optimized with lazy loading images and preloading assets for performance. Structured content data suggests a custom CMS backend. Performance is moderate with good SEO and accessibility features. No CMS like WordPress or Drupal detected. Hosting provider details are not explicit. Overall, the technical infrastructure supports a professional and scalable corporate website.
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.
