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

C-journal is a Korean business media platform targeting CEOs and global business leaders, providing management insights and business news. The website positions itself as a leading Korean business media outlet, focusing on delivering valuable content to its target audience. The business is registered under the name 비즈니스포스트 with clear contact information and a physical address in Seoul, Korea. However, the domain WHOIS data shows a future creation date (2025), which is unusual and may indicate a data error or pre-registration status. Technically, the website uses a moderate technology stack including jQuery 1.12.4, vis-network, and Google Tag Manager for analytics. Hosting appears to be on Amazon AWS infrastructure. The site is mobile optimized with good SEO and basic accessibility features. Security headers are present but could be enhanced with stricter policies and updated libraries to improve security posture. Security-wise, the site enforces HTTPS and has a Content-Security-Policy header, but the Referrer-Policy is set to 'unsafe-url', which is not recommended. No critical vulnerabilities or exposed sensitive data were detected. Privacy and cookie policies are not explicitly found, which is a compliance gap. Overall, the site demonstrates a good security posture but has room for improvement in privacy compliance and security header implementation. The overall risk assessment is moderate with recommendations to update security headers, improve privacy disclosures, and verify domain registration details. The site is trustworthy and professional but should address the noted anomalies and compliance gaps to enhance credibility and security.

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. 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 Privacy Policy found

      GDPR requires a clear and accessible privacy policy

      What to do: Add a comprehensive privacy policy page and link to it prominently

    • 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

C-journal operates as a specialized media outlet focusing on business and management content for CEOs and business leaders in Korea and globally. Its competitive advantage lies in its niche focus and professional content delivery. The business model is primarily content publishing with potential revenue streams from advertising and partnerships. The company appears small but well-positioned in the Korean media sector. The use of AWS hosting and Google Tag Manager indicates a modern digital infrastructure. No explicit partnerships or subsidiaries were identified. Growth indicators are not visible from the data, but the professional presentation suggests a stable operation.

Security posture

The website exhibits a moderate to good security maturity level with HTTPS enforced and several security headers implemented. The Content-Security-Policy is restrictive but allows 'unsafe-eval' and 'unsafe-inline', which could be tightened. The Referrer-Policy is set to 'unsafe-url', which is not ideal. The use of an outdated jQuery version (1.12.4) poses potential vulnerabilities. No incident response or security contact information is found, indicating a gap in security readiness. Privacy compliance is weak due to missing policies. Overall, the security posture is adequate for a media site but requires improvements in library updates, header policies, and privacy disclosures.

Recommendations

  1. Update jQuery and other JavaScript libraries to the latest secure versions to mitigate known vulnerabilities.
  2. Implement and publish comprehensive privacy and cookie policies to improve GDPR and privacy compliance.
  3. Enhance security headers by adding Strict-Transport-Security, X-Content-Type-Options, and X-Frame-Options headers.
  4. Review and tighten Content-Security-Policy to remove 'unsafe-eval' and 'unsafe-inline' if possible.
  5. Establish a dedicated security contact or incident response channel to improve security readiness and transparency.

Technical notes

Notes

The website uses a combination of jQuery 1.12.4, vis-network for network visualization, and Google Tag Manager for analytics and tracking. Hosting is on Amazon AWS infrastructure as indicated by the nameservers. The site is mobile responsive with good SEO meta tags and Open Graph data for social sharing. Accessibility features are basic but present. Performance is moderate, with no explicit speed optimizations detected. The site does not appear to use a CMS. The technical stack is modern but could benefit from updating legacy libraries and improving security configurations.
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.
