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

MEMX is a U.S.-based financial technology company operating regulated securities exchanges for equities and options. The company also offers a customizable exchange technology platform delivered as a SaaS solution, enabling other market operators to launch exchanges quickly. Positioned as an innovative alternative exchange operator, MEMX emphasizes efficiency, transparency, and cost reduction in capital markets trading. The website reflects a professional and consistent brand with clear messaging targeted at market participants and exchange members. Technically, the website leverages modern JavaScript frameworks such as Vue.js, integrates analytics and marketing tools like Google Tag Manager and Mailchimp, and is hosted on infrastructure associated with GoDaddy. The site is mobile-optimized, accessible, and SEO-friendly, with good performance metrics. Security is well implemented with HTTPS and no exposed sensitive data, though some security headers are missing and DNSSEC is not enabled. From a security posture perspective, MEMX demonstrates strong fundamentals but lacks explicit public security policies, incident response contacts, and cookie consent mechanisms, which may impact privacy compliance, especially under GDPR. The WHOIS data confirms a long-established domain with consistent registration details, supporting the legitimacy of the business. Overall, MEMX presents a credible and professional online presence with solid technical infrastructure and a good security baseline. Enhancements in privacy compliance and security transparency would further strengthen trust and regulatory alignment.

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

6 findings rated critical or high. Fix these first.

  1. 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"

    • 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';…

  2. 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

  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 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

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

MEMX operates in the competitive U.S. securities exchange market, offering both equities and options trading platforms. Its business model includes direct exchange operations and providing exchange technology as a service, targeting financial institutions and market participants seeking efficient trading solutions. The company benefits from regulatory approvals and a growing member base, positioning it as a credible alternative to incumbent exchanges. Strategic partnerships with authentication and onboarding platforms enhance operational capabilities. The company’s focus on technology innovation and SaaS delivery supports scalability and market expansion. Revenue streams likely include transaction fees, membership fees, and technology licensing. The website content and WHOIS data indicate a medium-sized enterprise with a stable market presence and growth potential.

Security posture

MEMX’s website employs HTTPS with strong SSL configuration, ensuring secure data transmission. The absence of DNSSEC and some recommended security headers (e.g., Content-Security-Policy) suggests room for improvement in domain and web security hardening. No vulnerabilities or exposed sensitive data were detected in the HTML content. The site uses secure forms integrated with Mailchimp for newsletter subscriptions. However, the lack of a published security policy or incident response contact information limits transparency and may hinder rapid response to security incidents. Privacy compliance is partial due to missing cookie consent mechanisms. Overall, the security posture is solid but could be enhanced by adopting additional security best practices and improving privacy disclosures.

Recommendations

  1. Enable DNSSEC on the domain to protect against DNS spoofing and improve domain security.
  2. Implement comprehensive security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to mitigate common web vulnerabilities.
  3. Publish a clear security policy and incident response contact information to improve transparency and preparedness.
  4. Add a cookie consent banner or mechanism to comply with GDPR and other privacy regulations.
  5. Regularly audit third-party scripts and tracking tools to minimize privacy risks and ensure compliance.

Technical notes

Notes

The website is built using modern web technologies including Vue.js and is powered by Craft CMS, indicating a contemporary and maintainable infrastructure. Integration with Google Tag Manager and LinkedIn Insight enables marketing analytics, while Mailchimp handles email subscriptions. Hosting appears to be managed via GoDaddy, with CDN usage for assets improving performance. The site is mobile responsive and accessible, with good SEO practices evident in meta tags and structured data. Performance is moderate, with video backgrounds and rich media content that may impact load times but enhance user experience. Technical debt appears low, though enabling DNSSEC and additional security headers would further modernize the security posture.
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.
