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

6 findings rated critical or high. Fix these first.

  1. SSL/TLS

    TLS encrypts the connection and proves the site is really yours. Weak or expiring certificates trigger browser warnings and put traffic at risk.

    • Critical

      Unable to retrieve SSL certificate

      Could not establish secure connection to retrieve certificate information

      What to do: Check if the server is accessible and SSL/TLS is properly configured

  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 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

    • 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

The website serves as a key digital channel for the Chosun Ilbo's Japanese edition, leveraging its market position as a leading Korean media outlet. Its business model is primarily advertising-driven, utilizing advanced header bidding and multiple ad networks to maximize revenue. The target audience includes Japanese readers interested in Korean news and culture. The site maintains consistent branding and content quality, supporting its large enterprise status. Partnerships with sister sites in Korean, English, and Chinese editions enhance its reach. The presence of comprehensive privacy and terms policies reflects a mature compliance posture. The company is headquartered in Seoul with transparent contact information, reinforcing trust.

Security posture

The site enforces HTTPS and uses clientTransferProhibited status to prevent unauthorized domain transfers, indicating good domain security practices. It employs a consent management platform aligned with IAB TCF v2 for GDPR compliance, showing attention to privacy regulations. However, the use of an outdated jQuery version (1.9.1) presents a potential security risk, and the absence of DNSSEC reduces DNS security. Missing security headers like Content-Security-Policy and X-Frame-Options could expose the site to certain web attacks. No exposed sensitive data or obvious vulnerabilities were detected in the HTML content. Overall, the security posture is solid but could be enhanced by updating libraries and adding recommended headers.

Recommendations

  1. Upgrade jQuery and other legacy JavaScript libraries to current secure versions to mitigate known vulnerabilities.
  2. Enable DNSSEC on the domain to improve DNS integrity and prevent spoofing.
  3. Implement additional HTTP security headers such as Content-Security-Policy, X-Content-Type-Options, and X-Frame-Options to strengthen defense against common web attacks.
  4. Conduct regular security audits of third-party scripts and ad networks to ensure no malicious code is introduced.
  5. Maintain and regularly update the consent management platform to comply with evolving privacy regulations and enhance user trust.

Technical notes

Notes

The website uses a custom CMS with a technology stack including Google Tag Manager, Google Adsense, DoubleClick for Publishers, BidStrap header bidding, Amazon Ads, and several third-party marketing and analytics tools. Fonts are loaded from Google Fonts, and jQuery 1.9.1 is used, which is outdated. The site is moderately performant with good mobile optimization and basic accessibility features. SEO is well addressed with proper meta tags and Open Graph data. Hosting provider details are not explicitly identified. The site uses asynchronous loading for scripts to improve performance. There is room for modernization, especially updating legacy libraries and enhancing security headers to reduce technical debt and improve resilience.
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.
