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

Bullish Global operates a regulated and audited cryptocurrency exchange platform offering institutional and advanced traders access to spot, derivatives, margin trading, and custody services. The company holds tier-1 licenses, is regulated by the Gibraltar Financial Services Commission, and is audited annually by Deloitte & Touche LLP. Bullish is recognized as a top-five global spot trading venue for Bitcoin, emphasizing its strong market position and liquidity. The platform targets institutional clients and professional investors, providing a unified trading account and API access for advanced trading features. Technically, Bullish employs a modern web infrastructure built on Next.js and React, hosted behind Cloudflare, with integrated analytics via Piwik PRO and Google Tag Manager. The website is fast, mobile-optimized, and accessible, reflecting a mature digital presence. Security practices include HTTPS enforcement, multi-layer custody safeguards, offline key management, and strict segregation of customer assets, supporting a high-security posture. The security posture is robust, with no detected vulnerabilities or exposed sensitive data. The company maintains full reserve backing of customer assets and enforces rigorous KYC/AML compliance. Privacy policies and cookie consent mechanisms are comprehensive and GDPR compliant. However, minor improvements such as enabling DNSSEC and publishing a security.txt file could enhance security transparency.

Strategic recommendations include enhancing DNS security, formalizing incident response contacts, and increasing transparency around data protection officer details to further strengthen trust and compliance.

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

1 finding rated critical or high. Fix these first.

  1. 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

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

Bullish Global is positioned as a leading institutional cryptocurrency exchange with a focus on regulated, transparent, and secure trading services. Its competitive advantages include tier-1 licensing, full reserve asset backing, and integration with institutional trading systems. The business model centers on providing a unified trading account for spot, margin, and derivatives trading, supported by a deep liquidity pool and low fees. Revenue streams likely derive from trading fees, margin interest, and custody services. The target customer segment is institutional investors and professional traders, with geographic focus including Gibraltar, Germany, Hong Kong, and other global markets. The company maintains a strong partnership ecosystem, including auditors like Deloitte and integration partners such as Trever. Growth indicators include active marketing campaigns, a professional trading competition, and API offerings. Strategic observations highlight the importance of regulatory compliance and security as key differentiators in the competitive crypto exchange market.

Security posture

Bullish demonstrates a mature security posture with multiple layers of protection for customer assets, including hardware, software, and operational safeguards. The platform operates as a full reserve exchange, ensuring a 1:1 ratio of customer assets and daily reconciliations. Cryptographic security and offline private key isolation are employed to prevent unauthorized transactions. The company enforces mandatory KYC/KYB and AML procedures, with ongoing transaction monitoring to detect suspicious activity. Annual audits by Deloitte reinforce financial transparency and trust. No direct incident response contacts were found, suggesting an area for improvement. The presence of a bug bounty program indicates proactive vulnerability management. Overall, Bullish aligns well with industry best practices but could enhance security transparency by publishing incident response contacts and a security.txt file.

Recommendations

  1. Enable DNSSEC on the domain to improve DNS security and prevent spoofing.
  2. Publish a security.txt file at the root domain to provide clear vulnerability disclosure contacts.
  3. Provide explicit incident response contact emails such as security@bullish.com or abuse@bullish.com.
  4. Disclose Data Protection Officer contact information to enhance GDPR compliance transparency.
  5. Regularly audit and update third-party scripts and analytics tools to mitigate supply chain risks.

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.
