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

Hyundai OCI Co., Ltd. operates as a leading manufacturer in the energy sector, specializing in the production of carbon black and BTX chemical products. The company positions itself as a technologically advanced and competitive player in the carbon black industry, targeting business customers and investors. The website reflects a professional corporate presence with clear branding and comprehensive business information, supported by a family of related companies under the HD Hyundai Group umbrella. Technically, the website employs standard web technologies including HTML5, CSS, JavaScript, and jQuery, hosted likely by Gabia, a reputable Korean hosting provider. While the site is accessible and well-structured, mobile optimization and accessibility are basic, and no CMS or advanced frameworks are detected. Security posture is moderate with HTTPS implied but lacking visible security headers or published security policies. Privacy compliance is partial, with a privacy policy present but no cookie consent mechanism. Overall, the domain registration is transparent and consistent with the business identity, enhancing trustworthiness.

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. Email security

    SPF, DKIM and DMARC stop others sending email that looks like it comes from your domain, a common route to phishing and invoice fraud.

    • Critical

      No email authentication configured

      Domain is vulnerable to email spoofing

      What to do: Implement SPF, DKIM, and DMARC immediately

  2. 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';…

  3. 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

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 company is part of the large HD Hyundai Group, with multiple related subsidiaries and partner companies linked on the website. Hyundai OCI focuses on chemical manufacturing, particularly carbon black used in rubber tires and BTX products used in various chemical applications. The business model centers on manufacturing and supplying these products to industrial clients. The website's recruitment postings and corporate information indicate a large enterprise with ongoing growth and investment in technology. The presence of multiple family sites and partner domains suggests a strong ecosystem and strategic partnerships within the energy and chemical sectors. The company maintains a professional online presence but could improve transparency in security and privacy practices to align with global standards.

Security posture

The website demonstrates a moderate security posture with HTTPS usage implied by canonical URLs but lacks explicit security headers such as Content Security Policy, HSTS, or X-Frame-Options. No security or incident response policies are published, and no dedicated contact channels for security incidents are found. The JavaScript libraries used are somewhat outdated (jQuery 1.8.2), which may pose vulnerabilities if not regularly updated. No forms are present on the main page, reducing attack surface, but external recruitment links lead to third-party sites. Privacy compliance is partial with a privacy policy but no cookie consent mechanism. Overall, the site is functional and secure enough for corporate informational purposes but would benefit from enhanced security best practices and compliance measures.

Recommendations

  1. Implement and enforce security headers such as CSP, HSTS, and X-Frame-Options to improve protection against common web attacks.
  2. Add a cookie consent banner and detailed cookie policy to comply with privacy regulations like GDPR.
  3. Publish a formal security policy and incident response contact information to enhance transparency and trust.
  4. Update JavaScript libraries and dependencies regularly to mitigate vulnerabilities.
  5. Improve mobile responsiveness and accessibility features to enhance user experience and compliance.

Technical notes

Notes

The website uses a traditional web stack with HTML5, CSS, and JavaScript, including jQuery 1.8.2 and TweenMax for animations. RequireJS is used for module loading. The site does not appear to use a CMS or modern frontend frameworks. Hosting is likely provided by Gabia, a Korean registrar and hosting provider. Performance is moderate with no explicit performance optimization scripts detected. SEO is supported by proper meta tags and Open Graph data. Accessibility and mobile optimization are basic but functional. The site structure is clear with well-organized navigation and family site links. There is room for modernization and technical improvements to enhance performance, security, and user experience.
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.
