Wise

Wise processes over £14 billion in cross-border payments each month, spanning 160+ countries and 40+ currencies. That kind of volume in international money movement means the attack surface is massive: credential stuffing on accounts holding 50+ currency balances, fraud vectors in real-time settlement, and the regulatory complexity of operating across dozens of jurisdictions simultaneously. Every transaction is a potential exploit point, and the stakes scale with the platform's reach. The company was founded in 2011 with a specific thesis: international banking's opacity - hidden fees, inflated exchange rates - is both a customer problem and a systemic vulnerability. Transparency isn't just a brand position here; it's an architectural decision that shapes how the platform handles data integrity, rate accuracy, and account security. The multi-currency account product lets users hold, spend, and send across borders, which means Wise is custodian of financial data across a uniquely broad threat landscape. For a security team, this is a fintech operating at infrastructure scale: real-time payment rails, cross-border regulatory compliance, and a user base that trusts the platform with funds in over 50 currencies. The mission to replace traditional international banking entirely means building systems that are faster and cheaper - but also resilient against the fraud, account compromise, and data exposure risks that come with moving serious money globally.
