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

Coinbase is a leading cryptocurrency exchange and financial services platform that enables individuals, businesses, and institutions to buy, sell, transfer, and store digital assets securely. The company offers a broad range of services including retail trading, advanced trading tools, institutional prime brokerage, developer APIs, and crypto wallet solutions. Coinbase positions itself as a trusted and secure platform with a strong market presence in the United States and globally. The website reflects a mature digital infrastructure with modern technologies and responsive design, supporting multiple languages and regions to cater to a diverse audience. Security practices are robust with HTTPS enforcement and secure form handling, though explicit security headers and incident response contacts could be improved. The absence of publicly available WHOIS data is unusual but likely due to registry privacy policies rather than malicious intent. Overall, Coinbase demonstrates a high level of professionalism, trustworthiness, and technical maturity.

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 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. 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. 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

Coinbase operates in the finance and technology sectors, focusing on cryptocurrency exchange and related services. Its business model revolves around transaction fees, institutional services, and value-added products like staking and crypto debit cards. The platform targets a wide audience from individual retail users to large institutions and developers. Coinbase's competitive advantage lies in its brand recognition, regulatory compliance, and comprehensive product suite. The company maintains a strong partnership ecosystem, including Ethereum Layer 2 solutions and developer toolkits, enhancing its market reach and innovation capabilities. Growth indicators include extensive language support and continuous product expansion. Strategic observations highlight Coinbase's emphasis on security, user experience, and regulatory adherence to maintain market leadership.

Security posture

Coinbase exhibits a mature security posture with mandatory HTTPS, secure data collection forms, and no visible exposure of sensitive information. The website lacks explicit security headers such as Content-Security-Policy, which could enhance protection against certain attacks. There is no public security.txt or incident response contact information, which are recommended best practices for vulnerability disclosure and incident management. Privacy compliance is strong with clear privacy and cookie policies, including consent mechanisms and GDPR adherence. No vulnerabilities or malware indicators were detected in the analyzed content. The overall security maturity is high but could benefit from enhanced transparency and additional security headers.

Recommendations

  1. Implement and publish a security.txt file to facilitate vulnerability reporting and improve transparency.
  2. Add comprehensive security headers such as Content-Security-Policy, X-Content-Type-Options, and X-Frame-Options to strengthen browser security.
  3. Provide clear incident response contact information on the website to improve trust and readiness.
  4. Regularly audit and update third-party libraries and dependencies to avoid vulnerabilities.
  5. Enhance privacy compliance disclosures with detailed data retention policies and user rights information.

Technical notes

Notes

The website uses a modern React-based front-end with ES modules and service workers for caching, indicating a progressive web application approach. Image assets leverage modern formats like AVIF and WebP for performance optimization. The site is mobile-optimized with responsive design and accessibility considerations. SEO is supported by proper meta tags, Open Graph, and JSON-LD structured data. No CMS or hosting provider details were explicitly detected. Performance appears fast with preloading of critical assets. Technical risks are minimal, but the absence of explicit security headers and WHOIS transparency are areas for improvement.
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.
