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"

  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. Email security

    SPF, DKIM and DMARC stop others sending email that looks like it comes from your domain, a common route to phishing and invoice fraud.

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 operates as a large-scale cryptocurrency exchange with a diversified business model that includes fiat-to-crypto purchases, spot and derivatives trading, and automated trading bots. Its competitive advantages include a broad selection of trading pairs, extensive payment options, and a user-friendly interface. The company targets retail and professional traders worldwide, supported by a comprehensive affiliate program and strategic partnerships with third-party payment processors. Growth indicators include continuous feature expansion, active community engagement, and recognition by reputable financial media. KuCoin's operational transparency is reinforced by detailed legal and compliance documents, although domain registration privacy limits external verification. The partnership ecosystem with payment providers like Banxa and Simplex enhances its fiat gateway capabilities, critical for user acquisition and retention.

Security posture

KuCoin exhibits a strong security posture with enforced HTTPS, multiple security headers, and mandatory two-factor authentication for critical operations. The platform uses Google Authenticator and email verification to secure user accounts and transactions. However, explicit public documentation on security policies, incident response, and vulnerability disclosure programs is limited or not found, which could be improved to enhance transparency and user trust. No obvious vulnerabilities or exposed sensitive data were detected in the website content. The absence of WHOIS transparency is common in the crypto industry for privacy reasons but should be balanced with clear security governance disclosures. Overall, KuCoin maintains a secure environment suitable for handling sensitive financial transactions but could benefit from publishing more detailed security governance information.

Recommendations

  1. Publish a dedicated security policy and incident response plan on the website to improve transparency.
  2. Establish and publicize a vulnerability disclosure or bug bounty program to encourage responsible reporting.
  3. Provide clear contact information for a Data Protection Officer or privacy contact to comply with data protection regulations.
  4. Enhance user education on security best practices and platform-specific risks.
  5. Regularly update WHOIS information or provide verified domain ownership statements to reduce suspicion.

Technical notes

Notes

The website is built on a modern React framework with extensive use of third-party libraries such as React Router, Redux, Emotion for styling, and Lottie for animations. It uses SystemJS for module loading and integrates advanced charting libraries for trading visualization. The site is optimized for performance with preloading of fonts and assets, and it supports multiple languages with hreflang tags for SEO. Accessibility and mobile responsiveness are well addressed. No CMS is explicitly detected, suggesting a custom or proprietary platform. Hosting details are not disclosed. The technical implementation reflects a mature and scalable infrastructure suitable for a high-traffic financial services platform.
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.
