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

HD현대오일뱅크 is a leading South Korean integrated energy company specializing in petroleum refining, petrochemical products, lubricants, and carbon black production. The company operates a large network of gas stations and charging stations nationwide. It holds a strong market position with advanced refining technology and a commitment to ESG principles. The website reflects a professional corporate presence with comprehensive business and sustainability information, targeting investors, customers, and job seekers. Technically, the website uses a traditional tech stack including jQuery 1.8.2, Swiper, TweenMax, and RequireJS, with Google Analytics for tracking. The site is moderately optimized for performance and accessibility, though some modernization opportunities exist. Security posture is good with HTTPS enforced and no visible sensitive data exposure, but lacks some security headers and explicit cookie consent mechanisms. The WHOIS data is transparent and consistent with the company's identity, registered with a reputable Korean registrar and showing no suspicious patterns. The domain is relatively new but aligns with corporate branding and restructuring. Overall, the site is trustworthy and professionally maintained. Recommendations include updating JavaScript libraries, implementing security headers, adding cookie consent for privacy compliance, and publishing security policies to enhance trust and compliance.

NIS2 Art. 21(2)

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

Business profile

HD현대오일뱅크 operates in the energy sector with a focus on refining and petrochemical production. It has a diversified business model including lubricant and carbon black production and retail fuel services. The company is part of the HD Hyundai group, with several subsidiaries linked via family sites. Market positioning is strong as a leader in refining profitability and technology in South Korea. The company targets a broad audience including consumers, investors, and potential employees. Growth indicators include ESG initiatives and expansion of clean energy projects. The partnership ecosystem is robust, linking multiple related companies under the HD Hyundai umbrella.

Security posture

The website demonstrates a mature security posture with HTTPS enforced and no exposed sensitive data. However, it lacks visible security headers such as Content-Security-Policy and X-Frame-Options, which are recommended for enhanced protection. The use of an outdated jQuery version (1.8.2) could pose security risks and should be updated. No incident response or security policy information is published, which could improve transparency and readiness. Privacy compliance is partial, with a privacy policy present but no cookie consent mechanism detected. Overall, the security posture is good but can be improved with modern best practices and compliance enhancements.

Recommendations

  1. Update JavaScript libraries, especially jQuery, to the latest secure versions.
  2. Implement and configure security headers like Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  3. Add a cookie consent banner or mechanism to comply with privacy regulations.
  4. Publish a clear security policy and incident response contact information on the website.
  5. Conduct regular security audits and penetration testing to identify and mitigate vulnerabilities.

Technical notes

Notes

The website uses a traditional front-end stack with jQuery 1.8.2, Swiper, TweenMax, and RequireJS for modular JavaScript loading. Google Analytics is integrated via gtag.js for user tracking. The site is hosted likely by Gabia, a Korean hosting provider, inferred from registrar and nameservers. Performance is moderate with room for improvement in mobile optimization and modern responsive design. Accessibility is good with ARIA and blind text elements for screen readers. SEO is supported by proper meta tags, Open Graph tags, and JSON-LD structured data. Technical debt is indicated by older library versions and lack of modern frameworks or CMS. Modernization opportunities include upgrading libraries, improving mobile responsiveness, and enhancing security headers.
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.
