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

CME Group Inc. operates as a leading global derivatives marketplace, offering a diverse range of futures and options products for risk management across multiple asset classes including agriculture, energy, equity indices, FX, interest rates, and metals. The company serves a broad audience of traders, investors, and financial institutions, providing comprehensive market data, clearing services, and technology solutions. The website reflects a mature, enterprise-level organization with consistent branding and high-quality content tailored to its professional audience. Technically, the website leverages modern technologies such as React, jQuery, and Adobe Experience Manager, hosted via Akamai CDN, and integrates various marketing and analytics tools including Google Tag Manager, Evergage, and OneTrust for cookie consent. The site is well-optimized for mobile and accessibility, with good SEO practices evident in meta tags and structured data. From a security perspective, while the site employs important security headers and cookie protections, the SSL/TLS configuration appears incomplete or misreported in the provided data, lacking valid certificates and modern protocol support. This represents a significant security concern that should be addressed promptly to ensure secure communications and user trust. Overall, CME Group's website is professional, content-rich, and business credible, but requires immediate attention to its SSL/TLS implementation to align with best security practices and maintain its high trustworthiness in the financial sector.

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.

    • Critical

      No HTTPS encryption

      GDPR requires appropriate security measures for personal data

      What to do: Implement SSL/TLS certificate for HTTPS

    • 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.

    • Critical

      No HTTPS Encryption

      Website does not use HTTPS encryption, making all data transmission vulnerable to interception

      What to do: Implement SSL/TLS certificate and redirect all HTTP traffic to HTTPS

  3. 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"

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

CME Group holds a dominant market position as the world's largest and most diverse derivatives marketplace. Its business model centers on providing futures and options trading, market data licensing, clearing services, and technology infrastructure. The company targets institutional and retail traders, risk managers, and financial professionals globally. Its extensive product portfolio across multiple asset classes and strong brand recognition provide competitive advantages. The website's integration with numerous partner domains and comprehensive educational resources indicates a robust partnership ecosystem and commitment to customer engagement. The mature domain age and strong domain protection further reinforce its established market presence.

Security posture

The website demonstrates a moderate security maturity level with the presence of key security headers such as HSTS and Content-Security-Policy, and secure cookie attributes. However, the absence of a valid SSL/TLS certificate and lack of support for modern TLS protocols (TLS 1.2 and 1.3) are critical vulnerabilities that expose the site to potential interception and downgrade attacks. The lack of OCSP stapling and session resumption further reduces security and performance. No exposed sensitive data or vulnerable libraries were detected in the HTML content. Incident response mechanisms are partially evident with a dedicated security concern reporting page. Overall, the security posture requires urgent improvements in SSL/TLS configuration and continuous monitoring to meet industry standards and regulatory compliance.

Recommendations

  1. Immediately install and configure a valid SSL/TLS certificate to enable HTTPS across the site.
  2. Enable support for modern TLS protocols (TLS 1.2 and TLS 1.3) and disable deprecated versions.
  3. Implement OCSP stapling and session resumption to improve security and performance.
  4. Regularly audit and update security headers and cookie settings to maintain best practices.
  5. Enhance incident response readiness by publishing clear security policies and contact information.
  6. Conduct periodic vulnerability assessments and penetration testing to identify and remediate risks.
  7. Maintain transparency with users regarding data protection and privacy compliance.
Technical notes

Notes

The website is built on a robust technical infrastructure using Apache server, React framework, and Adobe Experience Manager CMS, delivered via Akamai CDN for global performance. It incorporates modern JavaScript libraries and asynchronous loading for optimized user experience. The site includes comprehensive SEO meta tags, Open Graph, and Twitter card metadata for social media integration. Accessibility and mobile optimization are well addressed. However, performance metrics were not available, and SSL/TLS configuration appears incomplete or misreported, which is a critical technical risk. The site uses multiple marketing and analytics tools, including Google Tag Manager and OneTrust, indicating a mature digital marketing strategy. Overall, the technical stack is modern and scalable but requires immediate attention to security protocol implementation.
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.
