Common Securitization Solutions is a fintech company that builds and operates the backbone of the U.S. mortgage-backed securities market. Founded in 2013, its core product, the Common Securitization Platform (CSP), is a unified, cloud-native system that standardizes issuance and administration for government-sponsored enterprises. The platform currently processes trillions in securities, handling a critical 71% of the entire U.S. mortgage-backed securities market. The threat model is inherently systemic: a compromise or failure here doesn't just impact a single firm; it could cascade across the housing finance ecosystem.
The security challenge is embedded in a high-availability, cloud-native architecture that must meet the exacting reliability and compliance standards of the financial services sector. The technical domains center on securing complex cloud infrastructure, fintech systems, and the specific protocols governing securitization technology. This isn't a perimeter defense problem; it's about building and monitoring a platform where integrity and availability are existential, operating under intense regulatory scrutiny.
