Risk levelMedium

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

KakaoCloud is a Korean cloud service provider affiliated with the Kakao group, offering a broad range of cloud computing services including GPU instances, networking, storage, AI, and security solutions. The website demonstrates a mature digital presence with modern web technologies such as Next.js and React, hosted on AWS infrastructure with Megazone Corp. as the registrar and hosting partner. The site is well-designed, mobile-optimized, and provides clear navigation and business information targeting enterprises, startups, and public sector clients. However, explicit privacy and cookie policies are not found, and contact information is not clearly presented, which may impact user trust and compliance. Security posture is generally good with HTTPS and no exposed sensitive data, but lacks explicit security headers and published security policies. Overall, the domain registration data supports the legitimacy and consistency of the business claims.

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

5 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 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

KakaoCloud positions itself as a competitive cloud service provider in South Korea, leveraging Kakao's brand and technology to serve diverse sectors including gaming, startups, and government. The business model includes cloud service offerings, partner programs, and credit support initiatives to foster customer growth. The presence of major partners such as LG CNS, SK Telecom, and MegazoneCloud indicates a strong ecosystem. The company benefits from a domain age of over 10 years, reinforcing market stability. The website content and structure reflect a professional approach to customer engagement and service promotion.

Security posture

The website employs HTTPS and modern web frameworks, indicating a baseline secure environment. No sensitive data leakage or vulnerable libraries were detected in the HTML content. However, the absence of explicit security headers like Content-Security-Policy and lack of published security or incident response policies reduce the overall security maturity. No vulnerability disclosure or security.txt files were found, limiting transparency for security researchers. The site would benefit from enhanced security documentation and header implementation to improve defense-in-depth and compliance readiness.

Recommendations

  1. Publish comprehensive privacy and cookie policies with GDPR compliance details and consent mechanisms.
  2. Add explicit security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  3. Provide clear contact information including security incident response and abuse contacts.
  4. Implement and publish a vulnerability disclosure policy or security.txt file to encourage responsible reporting.
  5. Enhance transparency on data retention and user tracking practices to improve privacy compliance.

Technical notes

Notes

The website is built on a modern React/Next.js stack with Emotion for styling and Swiper.js for interactive components. Hosting is on AWS infrastructure with DNS managed by AWS name servers. Performance is optimized with preloading fonts and images, and the site is mobile responsive with good accessibility features. Google Tag Manager is used for analytics and marketing, indicating a mature digital marketing setup. The technical implementation is robust, but could be improved by adding CMS capabilities for easier content management and by enhancing security headers and policies.
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.
