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

Daum is a major South Korean web portal and media platform offering a wide range of services including news aggregation, search, live news streaming, and entertainment content. The website is well-established with a large audience and integrates content from reputable news sources and broadcasters. Technically, the site uses modern web technologies, including JavaScript, CSS, and integrates advertising networks such as Google Adsense and Kakao DAN. The site is mobile-optimized and provides a good user experience with clear navigation and relevant content. Security posture is solid with HTTPS enforced and no visible vulnerabilities, though security headers could be improved. Privacy compliance is limited due to the absence of visible privacy and cookie policies. WHOIS data is unavailable, likely due to privacy protection or query limitations, but the site’s legitimacy is supported by its content and partnerships. Overall, Daum is a credible and professional media portal with room for improvement in privacy transparency and security header implementation.

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. 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';…

  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

    • 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

Daum operates as a large media portal in South Korea, targeting a general audience with news, entertainment, sports, and live streaming services. Its business model revolves around content aggregation and advertising revenue, leveraging partnerships with major news organizations and broadcasters. The platform’s extensive content offerings and integration with KakaoTV for live streams position it strongly in the Korean media market. The absence of detailed WHOIS data is typical for large enterprises using privacy protection. Daum’s market position is strong, serving millions of users with diverse content and advertising solutions. The company likely benefits from a robust partnership ecosystem and a mature digital infrastructure supporting its operations.

Security posture

The website enforces HTTPS and uses deferred loading of scripts, which enhances security and performance. However, no explicit security headers such as Content-Security-Policy or X-Frame-Options were detected, which could improve protection against common web attacks. No exposed sensitive data or vulnerable libraries were found in the HTML snapshot. The lack of visible privacy and cookie policies indicates a gap in compliance with privacy regulations such as GDPR. Incident response and security contact information are not publicly available, which could hinder timely reporting of security issues. Overall, the security posture is good but could be enhanced by implementing recommended security headers and improving privacy transparency.

Recommendations

  1. Implement and publish comprehensive privacy and cookie policies to improve compliance and user trust.
  2. Add security headers like Content-Security-Policy, X-Frame-Options, and X-XSS-Protection to strengthen security posture.
  3. Provide clear contact information for security incidents and data protection inquiries.
  4. Regularly audit third-party scripts and advertising integrations to minimize security risks.
  5. Enhance accessibility features and SEO optimizations to improve user experience and search visibility.

Notes

The website uses a modern tech stack with HTML5, CSS, and JavaScript, including deferred script loading for performance optimization. It integrates Google Adsense and Kakao advertising networks and supports live streaming via KakaoTV. The site is responsive and optimized for mobile devices. No CMS was explicitly detected. Hosting provider details are not available from the HTML snapshot. Performance is moderate with room for improvement in accessibility and SEO.

Overall, the technical infrastructure is solid and supports a large-scale media portal effectively.
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.
