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

HD현대케미칼 is a South Korean petrochemical company specializing in the production and supply of various energy and chemical products such as LPG, naphtha, aviation fuel, diesel, and aromatic hydrocarbons. The company is part of the larger HD Hyundai conglomerate, with multiple related subsidiaries and partner companies linked through family site connections. The website presents a professional corporate image with clear business information and product descriptions targeted at industrial clients, investors, and potential employees. Technically, the site uses a traditional web stack with jQuery and RequireJS, hosted via Gabia, and employs HTTPS for secure communications. However, there is room for improvement in modern security practices, including the implementation of security headers and privacy compliance mechanisms. The WHOIS data is transparent and consistent with the company's identity, supporting the legitimacy of the domain and business. Overall, the website is well-structured and trustworthy but could enhance its privacy and security posture to align with best practices.

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 operates in the energy sector with a focus on petrochemical products essential for various industrial applications. Its market position is significant within South Korea, supported by its affiliation with HD Hyundai, a major conglomerate. The business model revolves around manufacturing and supplying chemical feedstocks and fuels, targeting industrial customers and investors. The website's family site links indicate a broad partnership ecosystem within the HD Hyundai group, enhancing business credibility and operational reach. Growth indicators include recent domain registration and active content updates. The company maintains a professional digital presence but lacks advanced marketing or analytics tools, suggesting a focus on corporate communication rather than direct consumer engagement.

Security posture

The website demonstrates a moderate security posture with HTTPS enabled and domain registration protections in place. However, the absence of visible security headers and lack of published security policies or incident response contacts indicate areas for improvement. No vulnerabilities or exposed sensitive data were detected in the provided content. The use of older JavaScript libraries like jQuery 1.8.2 may pose potential risks if not regularly updated. The site does not implement cookie consent mechanisms, which may affect GDPR compliance. Overall, the security maturity is adequate for a corporate informational site but should be enhanced to meet modern standards and regulatory requirements.

Recommendations

  1. Implement comprehensive security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to mitigate common web attacks.
  2. Add a cookie policy and consent mechanism to comply with GDPR and other privacy regulations.
  3. Publish a clear security policy and provide incident response contact information to improve transparency and trust.
  4. Update JavaScript libraries and dependencies regularly to avoid known vulnerabilities.
  5. Consider adding a vulnerability disclosure program or security.txt file to encourage responsible reporting of security issues.

Technical notes

Notes

The website uses a traditional front-end stack with HTML5, CSS, and JavaScript libraries including jQuery 1.8.2, TweenMax, and RequireJS. The site is hosted by Gabia, a reputable Korean hosting provider, as indicated by the registrar and nameservers. Performance is moderate with video content on the main page, which may impact load times. Mobile optimization is basic but functional. SEO is supported by proper meta tags and Open Graph properties. No CMS or modern frameworks were detected, suggesting a custom or legacy-built site. Accessibility features are minimal but present, such as skip links and language selection. The site could benefit from modernization to improve performance, accessibility, and maintainability.
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.
