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

SK Square CO., LTD. is a South Korean investment company specializing in the semiconductor and ICT platform sectors. The company manages a portfolio of high-potential growth companies, including subsidiaries such as SK하이닉스, SK쉴더스, 11번가, 티맵모빌리티, and others. The website provides comprehensive investor relations, ESG, and sustainability information, targeting investors and stakeholders interested in technology investments. The business model focuses on active portfolio management and value creation in the semiconductor and ICT industries. Technically, the website employs modern web technologies including jQuery, Bootstrap 4.6, Swiper.js for carousels, GSAP for animations, and integrates Google Analytics and Google Tag Manager for tracking. The site is mobile-optimized, accessible, and SEO-friendly with proper meta tags and Open Graph data. Performance is moderate with good user experience and navigation clarity. From a security perspective, the site enforces HTTPS and uses secure cookies but lacks visible security headers and a cookie consent mechanism. No exposed sensitive data or vulnerable libraries were detected. The WHOIS data is missing or inaccessible, which raises some concerns about domain registration transparency, though the website content and branding strongly indicate legitimacy. Overall, the website is professional and trustworthy with room for improvement in privacy compliance and security best practices. Strategic recommendations include implementing security headers, adding cookie consent banners, publishing security policies, and verifying domain registration details for enhanced trust.

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

5 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 Cookie Policy found

      GDPR requires clear information about cookie usage

      What to do: Add a dedicated cookie policy explaining cookie usage and purposes

    • High

      No Cookie Consent Banner found

      GDPR requires explicit consent for non-essential cookies

      What to do: Implement a cookie consent banner that appears on first visit

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

SK Square holds a strong market position as a leading investment company in South Korea's semiconductor and ICT sectors. Its competitive advantage lies in its diversified portfolio of subsidiaries and strategic investments in high-growth technology companies. The business model revolves around active portfolio management, value enhancement, and ESG-driven sustainability initiatives. Revenue streams likely include investment returns and dividends from subsidiaries. The target customer segments include institutional investors, shareholders, and strategic partners. Growth indicators are positive with recent investments in AI and semiconductor companies. The partnership ecosystem is extensive, linking multiple subsidiaries and related technology firms. The company's operations reflect a mature and strategic approach to technology investment and innovation.

Security posture

The website demonstrates a moderate to good security maturity level. HTTPS is enforced, and secure cookie attributes are set, indicating attention to transport security and session protection. However, the absence of key security headers such as Content-Security-Policy, X-Content-Type-Options, and Strict-Transport-Security reduces the overall security posture. No vulnerabilities or exposed sensitive data were found in the HTML content. Compliance gaps include lack of visible cookie consent mechanisms and absence of published incident response or security policies. Data protection practices appear basic with no explicit DPO contact or vulnerability disclosure program. Incident response readiness and security culture indicators are not evident from the website content. Overall, the security posture is adequate but could be strengthened with additional controls and transparency.

Recommendations

  1. Implement comprehensive security headers including Content-Security-Policy, X-Content-Type-Options, X-Frame-Options, and Strict-Transport-Security to enhance protection against common web attacks.
  2. Deploy a cookie consent banner or mechanism to comply with privacy regulations and improve user transparency regarding data collection.
  3. Publish a dedicated security policy and incident response information page to demonstrate commitment to security and provide clear contact channels.
  4. Consider establishing a vulnerability disclosure program and hosting a security.txt file to facilitate responsible reporting of security issues.
  5. Enhance visibility of contact information for privacy and security concerns, including a designated Data Protection Officer contact if applicable.

Technical notes

Notes

The website is built using a modern and robust technology stack including jQuery 3.6.0, Bootstrap 4.6 for responsive design, Swiper.js for interactive carousels, GSAP for animations, and WOW.js for scroll animations. FontAwesome is used for icons, and Google Analytics and Tag Manager are integrated for analytics and marketing purposes. The site is mobile-optimized with good accessibility features and SEO meta tags including Open Graph data. Performance is moderate, with asynchronous loading of analytics scripts and efficient use of CSS and JS assets. No CMS was detected, suggesting a custom or proprietary platform. Hosting provider details are not disclosed. The technical implementation is solid with opportunities to improve security headers and privacy compliance mechanisms.
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.
