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

Kakao is a leading South Korean technology conglomerate specializing in a broad range of digital services including communication platforms, financial services, mobility, entertainment, and social impact initiatives. The company maintains a strong market position with a diversified portfolio of subsidiaries and services targeting both consumers and businesses. The website reflects a mature digital presence with comprehensive content, clear navigation, and consistent branding. Technically, the site leverages modern JavaScript frameworks (likely Vue.js/Nuxt.js), integrates official SDKs, and employs tracking technologies such as Google Tag Manager and Facebook Pixel. The site is mobile-optimized and demonstrates good performance and accessibility standards. From a security perspective, the website enforces HTTPS and avoids exposing sensitive data. However, it lacks explicit security headers and publicly available incident response or vulnerability disclosure information. Privacy policies are comprehensive and GDPR-compliant, though cookie consent mechanisms could be improved. Overall, the website presents a low-risk profile with strong business credibility and technical maturity. The absence of WHOIS data is noted but does not detract significantly from the legitimacy given the extensive corporate footprint and linked domains.

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 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

  3. 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.

    • High

      Weak Protocols Supported

      Server supports weak protocols: TLSv1.1

      What to do: Disable TLS 1.0, TLS 1.1, and all SSL versions

      • CWE-327
      • OWASP A04:2025
      • ASVS V12.1.1

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

Kakao operates as an essential entity in the technology sector with significant influence in media, finance, and e-commerce. Its business model revolves around providing integrated digital services that enhance daily life and business operations. Revenue streams likely include advertising, subscription services, financial transactions, and platform fees. The company targets a wide audience including individual consumers, small businesses, and enterprise clients. Growth indicators include active development of AI services, strategic partnerships, and expansion of social impact projects. The extensive partner and subsidiary ecosystem supports a robust market presence and diversified operations.

Security posture

Kakao's security posture is solid with mandatory HTTPS and no visible exposure of sensitive information. The use of official SDKs and scripts reduces risk from third-party components. However, the lack of security headers and absence of public incident response or vulnerability disclosure channels represent areas for improvement. Compliance with privacy regulations is evident, but cookie consent practices could be enhanced. The security culture appears mature but would benefit from greater transparency and formalized security communication channels.

Recommendations

  1. Implement comprehensive security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to enhance protection against common web attacks.
  2. Publish a dedicated vulnerability disclosure policy and incident response contact information to improve transparency and community trust.
  3. Introduce a clear cookie consent mechanism to align with GDPR and other privacy regulations.
  4. Regularly audit and update third-party scripts and SDKs to mitigate risks from external dependencies.
  5. Enhance security awareness and communication internally and externally to foster a stronger security culture.

Technical notes

Notes

The website is built on a modern JavaScript framework, likely Vue.js with Nuxt.js for server-side rendering, ensuring good SEO and performance. It uses official Kakao SDKs and integrates with Google Tag Manager and Facebook Pixel for analytics and marketing. The site is well-structured with responsive design and accessibility features. Performance appears optimized with preloading of critical assets. No CMS is explicitly detected, suggesting a custom or proprietary platform. Hosting provider details are not disclosed. Technical risks are minimal but could include dependency on third-party scripts and lack of certain security headers.
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.
