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

GMX is a decentralized perpetual exchange platform enabling leveraged trading of major cryptocurrencies such as BTC, ETH, and AVAX on the Arbitrum and Avalanche blockchains. The platform targets cryptocurrency traders seeking decentralized finance solutions with up to 100x leverage and liquidity provision opportunities. GMX has established a significant market presence with over $322 billion in total trading volume and a user base exceeding 720,000. The business model revolves around decentralized trading, liquidity provision, and governance via utility tokens GMX, GLV, and GM. Technically, the website employs a modern React-based frontend with Web3 integration, hosted on NS1 DNS infrastructure, and optimized for performance and mobile use. However, the site lacks some compliance elements such as privacy and cookie policies, and security headers are not detected, which could be improved to enhance security posture and regulatory compliance. Overall, GMX demonstrates a mature and professional digital presence with strong trust indicators but should address privacy and security policy gaps to strengthen its risk profile.

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.

Priority findings

6 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 Privacy Policy found

      GDPR requires a clear and accessible privacy policy

      What to do: Add a comprehensive privacy policy page and link to it prominently

    • 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

    • High

      Third-party services without privacy policy

      Detected services: Twitter

      What to do: Document all third-party data sharing in your privacy policy

  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

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

GMX operates in the competitive decentralized finance sector, focusing on perpetual futures trading with high leverage. Its competitive advantages include multi-chain deployment (Arbitrum and Avalanche), a large and active user base, and a governance model that empowers token holders. Revenue streams derive from trading fees distributed to token holders and liquidity providers. The platform appeals primarily to experienced crypto traders and DeFi participants. GMX maintains an active ecosystem with governance, voting, and open-source protocol development on GitHub. Strategic observations include the need to enhance compliance transparency and security best practices to maintain trust and regulatory alignment as the DeFi space evolves.

Security posture

The security posture of GMX is moderate to good. The platform uses HTTPS and has domain transfer protections in place. However, DNSSEC is not enabled, and no security headers were detected in the provided data, which are important for mitigating common web attacks. The absence of published security policies, incident response contacts, and vulnerability disclosure mechanisms indicates gaps in formal security governance and transparency. No vulnerabilities or exposed sensitive data were found in the analysis. To improve, GMX should implement DNSSEC, add security headers, publish privacy and security policies, and establish clear incident response and vulnerability disclosure channels.

Recommendations

  1. Enable DNSSEC on the domain to improve DNS security.
  2. Implement and publish a comprehensive privacy policy and cookie consent mechanism to enhance compliance.
  3. Add essential security headers such as Content-Security-Policy, Strict-Transport-Security, and X-Frame-Options.
  4. Establish and publicize an incident response process and vulnerability disclosure policy, including security contact emails.
  5. Regularly audit and update third-party libraries and dependencies to avoid vulnerabilities.

Technical notes

Notes

GMX's technical infrastructure is modern and well-implemented, leveraging React and Web3 technologies for a responsive and interactive user experience. The site is hosted with reputable DNS providers and optimized for performance and mobile devices. However, the lack of DNSSEC and security headers represents technical debt in security hardening. The absence of CMS suggests a custom or static site approach, which can be beneficial for security if properly maintained. The platform's multi-chain support (Arbitrum and Avalanche) indicates advanced blockchain integration capabilities. Opportunities exist to improve accessibility and SEO further by adding ARIA attributes and structured data markup.
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.
