CEX.IO LTD, founded in 2013, operates a regulated cryptocurrency platform that sits squarely at the intersection of fintech and financial infrastructure. The company holds 30+ licenses worldwide and processes serious volume - $7.5 billion in customer deposits since 2019 across 15 million+ registered users. It runs operations in 30+ U.S. states. That's a wide attack surface spanning custody, trading, staking, and savings products, all under jurisdictions with overlapping and evolving compliance requirements.
The threat model here is familiar to anyone in crypto: the company builds and maintains infrastructure for spot trading, instant buy/sell, staking, savings accounts, and a comprehensive wallet solution. Security and regulatory compliance are listed as core technical domains alongside blockchain and platform development. For a platform managing billions in deposits, that means securing hot and cold wallets, hardening APIs against abuse, maintaining transaction integrity across chains, and keeping pace with regulatory frameworks that shift by jurisdiction and quarter.
The team operates globally with a stated focus on removing technical barriers - building platforms accessible to both beginners and professionals. In practice, that means the security engineering challenge isn't just about defending a single perimeter; it's about protecting systems designed to onboard users who may have minimal crypto experience, which shapes how authentication, fraud detection, and key management need to work.
