360 Treasury Systems AG

360T runs one of the planet's largest web-based OTC trading platforms - connecting over 2,900 buy-side firms to more than 200 liquidity providers for FX, derivatives, and increasingly, digital assets. Founded in 2000 and headquartered in Frankfurt with offices in New York and Singapore, the company has spent two decades building the plumbing that moves institutional money across borders. The attack surface here isn't theoretical: you're protecting real-time execution workflows where a compromised session or manipulated price feed can mean eight-figure losses in seconds. The tech stack spans products like EMS, Bridge, SuperSonic Trader, and the Active Trading Suite - web-based systems that handle sensitive order flow, counterparty data, and settlement logic across banking, corporate treasury, and institutional investment verticals. The newer 3DX platform extends this into crypto-asset trading under MiCAR regulation, adding blockchain-adjacent threat models to the mix. Expect to work across traditional appsec, API security, infrastructure hardening, and regulatory compliance - particularly where latency-sensitive trading meets stringent European financial oversight. This isn't a fintech startup guessing at security posture. It's a mature, regulated trading venue where security teams must balance real-time performance demands against the reality that financial infrastructure is a persistent target for nation-state actors, fraud operations, and sophisticated credential attacks. The team operates across three continents, serving banks, brokers, and institutional desks that depend on platform integrity for every transaction.
