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

CryptoCompare is a well-established online platform providing comprehensive cryptocurrency market data, including live prices, charts, portfolio tracking, news, and community forums. It serves a target audience of cryptocurrency traders, investors, and enthusiasts, positioning itself as a key data aggregator and community hub in the crypto finance sector. The website integrates with CoinDesk data, enhancing its market credibility and data quality. Technically, the site employs modern web technologies such as AngularJS, Google Tag Manager, reCAPTCHA, and secure WebSocket connections, ensuring a robust and interactive user experience. Mobile optimization and SEO practices are well implemented, contributing to good performance and accessibility, although accessibility features could be improved. Security-wise, the site enforces HTTPS, uses OAuth2 authentication via Auth0, and incorporates bot prevention mechanisms, reflecting a strong security posture. However, the absence of visible privacy, cookie, and terms of service policies, as well as lack of WHOIS registrant data, slightly diminish trust and privacy compliance. Overall, CryptoCompare presents a professional and secure platform with moderate risk, primarily due to incomplete public privacy disclosures and WHOIS opacity.

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. 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 Protocols Supported

      Server supports weak protocols: TLSv1.1

      What to do: Disable TLS 1.0, TLS 1.1, and all SSL versions

      • CWE-327
      • OWASP A04:2025
      • ASVS V12.1.1
    • 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

CryptoCompare operates in the competitive cryptocurrency data and analytics market, leveraging partnerships with CoinDesk and integrating affiliate marketing for gambling and crypto trading platforms. Its business model centers on providing free market data and community features while monetizing through advertising and affiliate programs. The platform targets adult users interested in crypto markets and gambling, with clear age restrictions and responsible gambling disclaimers. The company demonstrates consistent branding and good content quality, supporting a large user base. However, the lack of explicit company contact information and privacy policies may impact user trust and regulatory compliance. The platform's ecosystem includes multiple external domains for data, authentication, and marketing, indicating a complex but well-integrated operational structure.

Security posture

CryptoCompare exhibits a mature security posture with enforced HTTPS, secure authentication via Auth0, and bot mitigation using Google reCAPTCHA. The use of secure WebSocket connections and modern JavaScript frameworks further enhances security. Despite these strengths, the absence of publicly accessible security policies, incident response contacts, and vulnerability disclosure mechanisms represents a compliance gap. No obvious vulnerabilities or exposed sensitive data were detected in the analyzed content. The site would benefit from publishing a security.txt file and detailed privacy and cookie policies to improve transparency and regulatory adherence, especially under GDPR and similar frameworks.

Recommendations

  1. Publish comprehensive privacy and cookie policies prominently linked on the website to improve privacy compliance and user trust.
  2. Implement and disclose a formal security policy and incident response plan, including contact channels for security issues.
  3. Add a security.txt file to facilitate responsible vulnerability disclosure and improve security transparency.
  4. Enhance accessibility features to meet recognized standards and improve usability for all users.
  5. Regularly audit third-party scripts and dependencies to mitigate risks from vulnerable libraries and ensure up-to-date security.

Technical notes

Notes

The website is built on AngularJS with integration of Google Tag Manager and reCAPTCHA for analytics and security. It uses Typekit fonts for branding consistency and secure WebSocket connections for real-time data streaming. The site is mobile-optimized with responsive design and includes OAuth2 authentication via Auth0. Performance is moderate with room for improvement in accessibility and SEO. Hosting provider details are not explicit, and no CMS is detected. The technical infrastructure supports a dynamic and interactive user experience but should be regularly updated to mitigate risks associated with AngularJS's aging framework.
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.
