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

OKX is a globally recognized cryptocurrency exchange founded in 2017, offering a comprehensive suite of crypto trading and financial services including spot, futures, options trading, P2P trading, and Web3 wallet integration. The platform targets a broad audience of crypto traders and investors worldwide, positioning itself as a leading player in the digital asset exchange market. The website demonstrates a high level of digital maturity with modern technologies such as React, real-time WebSocket connections, and advanced analytics tools, ensuring a fast, responsive, and user-friendly experience across devices. Security posture is strong with HTTPS enforcement, fraud detection scripts, and cookie consent mechanisms, although explicit security policies and incident response details are not publicly disclosed. The absence of WHOIS data suggests privacy protection typical in the crypto industry, which while common, requires cautious trust evaluation. Overall, OKX presents a professional, trustworthy, and technically robust platform with strong branding and compliance indicators.

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

3 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 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

  2. 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 SSL Key Length

      SSL certificate uses 256-bit key, which is considered weak

      What to do: Use at least 2048-bit RSA or 256-bit ECC key

      • CWE-326
      • OWASP A04:2025
      • Mozilla TLS: Mozilla Server Side TLS 6.0 intermediate: rsa_key_size 2048

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

OKX operates in the finance and technology sectors as a large enterprise cryptocurrency exchange. Its business model revolves around providing crypto trading, earning, and institutional solutions globally. The company leverages partnerships with high-profile brands like McLaren and Manchester City to enhance market credibility. Revenue streams likely include trading fees, lending interest, and institutional services. The platform supports over 180 regions and integrates advanced trading tools and APIs, appealing to both retail and institutional clients. Growth indicators include extensive product offerings, a global user base, and active community engagement through social media and referral programs. Strategic observations highlight a focus on innovation, compliance with regional regulations, and expansion into Web3 services.

Security posture

The security maturity of OKX is high, with enforced HTTPS, use of fraud detection technologies like ThreatMetrix, and comprehensive cookie consent management. The website avoids exposing sensitive data and employs secure input fields. However, the lack of publicly available detailed security policies, incident response plans, and certifications represents a compliance gap. No vulnerabilities or outdated libraries were detected in the analyzed content. The platform would benefit from publishing explicit security frameworks and incident response contacts to enhance transparency and user trust. Overall, the security posture supports business continuity and user protection but could improve in documented governance and communication.

Recommendations

  1. Publish detailed security policies and incident response procedures publicly to improve transparency and user trust.
  2. Ensure all recommended security headers (CSP, X-Frame-Options, X-Content-Type-Options) are explicitly implemented and documented.
  3. Regularly audit and disclose compliance with relevant data protection regulations such as GDPR and NIS2.
  4. Enhance communication channels for security incident reporting, including dedicated security@ or abuse@ email addresses.
  5. Maintain and publicize certifications and third-party audits to strengthen credibility and compliance posture.

Technical notes

Notes

OKX's technical infrastructure is modern and robust, leveraging React for frontend development, real-time WebSocket connections for trading data, and advanced analytics platforms like Amplitude and Google Tag Manager. The website is optimized for performance and mobile responsiveness, with a clean, professional design and clear navigation. Use of CDN-hosted multimedia content and lazy loading techniques further enhance user experience. No CMS was detected, indicating a custom-built platform likely tailored for scalability and security. Technical risks are minimal based on available data, but continuous monitoring and modernization are advised to maintain competitive advantage and operational stability.
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.
