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

Okcoin is a globally recognized cryptocurrency exchange platform that facilitates the buying, selling, and trading of digital assets such as Bitcoin, Ethereum, and Dogecoin. The platform also offers crypto rewards through its earning programs, targeting a broad audience of crypto traders and investors worldwide. The website presents a professional and consistent brand image, supported by comprehensive privacy and cookie policies, and employs modern web technologies including React, jQuery, and secure WebSocket connections. Security measures such as HTTPS enforcement, ThreatMetrix fraud detection, and OneTrust cookie consent are implemented, reflecting a mature security posture. However, the absence of publicly disclosed security policies, incident response plans, and vulnerability disclosure programs indicates areas for improvement in transparency and security culture. The WHOIS data is unavailable, which limits the ability to fully verify domain registration legitimacy, but the overall website quality and trust indicators suggest a credible business. Strategic recommendations include publishing explicit security and incident response information, enhancing accessibility, and establishing a vulnerability disclosure channel.

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

4 findings rated critical or high. Fix these first.

  1. 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.

    • Critical

      Unable to retrieve SSL certificate

      Could not establish secure connection to retrieve certificate information

      What to do: Check if the server is accessible and SSL/TLS is properly configured

  2. 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 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';…

  3. 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

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

Okcoin operates in the finance and technology sectors as a large-scale cryptocurrency exchange. Its business model revolves around providing a secure and user-friendly platform for digital asset trading and crypto rewards. The company targets global crypto users, leveraging partnerships with payment processors and employing advanced fraud detection technologies. The website's content and design quality support its market position as a leading digital asset exchange. While the domain registration details are not publicly available, the company's digital presence and compliance with privacy regulations indicate operational maturity. Growth indicators include multi-language support and regional site versions. The absence of detailed business registration information and physical addresses suggests a focus on digital-first operations.

Security posture

The website demonstrates a solid security posture with HTTPS enforced, modern security headers, and integration of third-party fraud detection services like ThreatMetrix. Cookie consent is managed via OneTrust, supporting GDPR compliance. No critical vulnerabilities or exposed sensitive data were detected in the analysis. However, the lack of a published security policy, incident response plan, and vulnerability disclosure program limits transparency and may impact user trust. The site uses secure WebSocket connections and up-to-date libraries, but continuous monitoring and timely updates are recommended. Overall, the security maturity is good but could benefit from enhanced communication of security practices and readiness.

Recommendations

  1. Publish a detailed security policy and incident response plan on the website.
  2. Implement and publicize a vulnerability disclosure program or security.txt file.
  3. Enhance website accessibility to meet higher compliance standards.
  4. Disclose data protection officer contact information to improve GDPR transparency.
  5. Regularly audit and update third-party libraries to mitigate potential vulnerabilities.

Overall, the technical infrastructure supports a scalable and secure digital asset exchange 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.
