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

KuCoin operates as a major global cryptocurrency exchange platform offering a wide range of services including spot trading, futures, margin trading, lending, staking, and API access. The platform targets cryptocurrency traders and investors worldwide and positions itself as a leader in Web 3.0 adoption. The website is professionally designed, mobile-optimized, and supports multiple languages, reflecting a mature digital infrastructure. The technical stack is modern, leveraging React and associated libraries, with integrations for analytics and error tracking. Security features such as HTTPS, 2FA via Google Authenticator, and email verification are implemented, indicating a strong security posture. However, the absence of WHOIS data reduces transparency and slightly impacts trustworthiness. Overall, KuCoin presents a robust, secure, and user-friendly platform with comprehensive compliance and legal documentation.

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

7 findings rated critical or high. Fix these first.

  1. 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

    • High

      Third-party services without privacy policy

      Detected services: Google Analytics

      What to do: Document all third-party data sharing in your privacy policy

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

KuCoin's market position as a leading cryptocurrency exchange is supported by its extensive user base of over 40 million users and licensing under ASIC AFSL No. 297499. The business model revolves around facilitating crypto asset trading and related financial services, generating revenue through trading fees, lending interest, and affiliate programs. The company maintains a broad partnership ecosystem and localized presence, as seen with kucoin.th. Growth indicators include continuous feature expansion such as AI-powered trading bots and futures products. The platform's comprehensive legal and compliance framework supports its global operations, although domain registration opacity warrants monitoring.

Security posture

KuCoin demonstrates a mature security posture with enforced HTTPS, multiple security headers, and multi-factor authentication mechanisms. The platform employs Google Authenticator for 2FA and email verification for sensitive operations like withdrawals and API creation. While no explicit vulnerabilities were detected in the analyzed content, the lack of a public vulnerability disclosure policy and security.txt file suggests room for improvement in transparency and incident response readiness. Compliance with GDPR and other privacy regulations is evident through detailed privacy and cookie policies. Overall, KuCoin balances user security with usability effectively but should enhance public security communication.

Recommendations

  1. Implement and publish a formal vulnerability disclosure and bug bounty program to encourage responsible reporting.
  2. Enhance visibility and accessibility of incident response contacts and procedures on the website.
  3. Publish a security.txt file to align with emerging security best practices and improve transparency.
  4. Regularly audit and update third-party libraries to mitigate risks from vulnerable dependencies.
  5. Maintain clear and accessible data retention and privacy compliance documentation to strengthen user trust.

Technical notes

Notes

The website is built on a modern React-based tech stack with extensive use of JavaScript libraries and UI frameworks such as Kufox MUI and Emotion for styling. It leverages SystemJS for module loading and integrates advanced charting libraries for trading visualization. Performance is optimized with preloading of fonts and assets, and the site is mobile-responsive with good accessibility features. Analytics and error tracking are implemented via Google Analytics, Tag Manager, and Sentry. No CMS or hosting provider details were explicitly detected. The technical infrastructure supports a high-quality user experience but requires ongoing maintenance to manage technical debt and security risks.
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.
