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

Cafe24 Corp. is a South Korean technology company specializing in providing a comprehensive global e-commerce platform. Their services include commerce platform solutions, global market expansion support, store and design services, marketing, hosting, and entrepreneurship education. The company positions itself as a leader in the Korean e-commerce ecosystem with a strong partner network and a focus on enabling global online business success. The website content is professionally presented in Korean with multilingual support, targeting online merchants and businesses seeking e-commerce solutions. Technically, the website uses modern JavaScript libraries such as jQuery 3.6.0 and Google Tag Manager for analytics and marketing. The site is mobile-optimized with good SEO practices and a moderate performance profile. However, some accessibility features are basic, and no CMS or specific frameworks are detected. Hosting appears to be managed internally or through Cafe24's own infrastructure. From a security perspective, the site enforces HTTPS and uses standard tracking scripts without visible vulnerabilities or exposed sensitive data. However, the absence of security headers and cookie consent mechanisms indicates room for improvement in security best practices and privacy compliance. The WHOIS data is missing or unavailable, which raises some concerns about domain registration transparency, though the website content and branding suggest a legitimate business. Overall, Cafe24's website is a well-structured, professional platform supporting a large e-commerce business. Strategic recommendations include enhancing security headers, implementing GDPR-compliant cookie consent, publishing security policies, and clarifying domain registration information to improve trust and compliance.

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. Network security

    Services reachable from the internet are the first thing attackers probe. Anything open that does not need to be should be closed.

    • Critical

      Critical Service Exposed: MySQL

      Port 3306 (MySQL) is publicly accessible - MySQL - Database server

      What to do: Immediately restrict access to MySQL using firewall or VPN

      • NIS2 21(2)(e)
      • IR 2024/2690 6.7.2(f): Implementing Regulation (EU) 2024/2690, Annex point 6.7.2(f): Network security
      • NIST CM-7: NIST SP 800-53 Rev. 5 CM-7: Least Functionality
      • NIST SC-7: NIST SP 800-53 Rev. 5 SC-7: Boundary Protection

  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

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 · found on this site
  • 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

Cafe24 operates as a major e-commerce platform provider in South Korea, targeting online merchants and global businesses. Their competitive advantage lies in offering an integrated suite of services including hosting, marketing, design, and education, enabling clients to build and scale online stores globally. The company maintains a robust partnership ecosystem with major marketplaces, payment gateways, and logistics providers. Revenue streams likely include platform subscriptions, transaction fees, and value-added services. Growth indicators include active media presence, continuous service expansion, and strategic partnerships. The company’s operations reflect a mature business model focused on technology-driven e-commerce enablement.

Security posture

The security posture of Cafe24's website is moderate to good. HTTPS is enforced, and no critical vulnerabilities or exposed sensitive data were detected in the analyzed content. However, the lack of security headers such as Content-Security-Policy, X-Frame-Options, and X-XSS-Protection reduces the overall security hardening. Privacy compliance is partial, with a privacy policy present but no cookie consent mechanism or explicit GDPR compliance indicators. Incident response and security policy information are not publicly available, which may impact transparency. The use of third-party scripts is standard but should be regularly audited. Overall, the site demonstrates a baseline security maturity but would benefit from enhanced security controls and compliance measures.

Recommendations

  1. Implement comprehensive security headers including Content-Security-Policy, X-Frame-Options, and X-XSS-Protection to mitigate common web attacks.
  2. Deploy a cookie consent banner and update privacy policies to ensure full GDPR and global privacy regulation compliance.
  3. Publish a clear security policy and incident response contact information to improve transparency and trust.
  4. Regularly audit and update third-party scripts and libraries to avoid vulnerabilities.
  5. Clarify domain registration details and ensure WHOIS information is accurate and publicly available to enhance legitimacy and trust.

Technical notes

Notes

The website uses a traditional jQuery-based front-end with additional plugins like TouchSlider for UI interactions. Google Tag Manager and Google Analytics are integrated for tracking and marketing analytics. The site is served over HTTPS with good SSL configuration. The HTML structure is valid and includes meta tags for SEO and social media sharing (Open Graph). Mobile optimization is good with responsive design elements. Accessibility features are basic, with skip navigation links present. No modern JavaScript frameworks (React, Angular, Vue) or CMS platforms were detected, indicating a possibly custom or legacy front-end. Hosting appears to be managed by Cafe24 or related infrastructure. Performance is moderate with room for optimization. Overall, the technical stack is stable but could benefit from modernization and enhanced accessibility.
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.
