Common Securitization Solutions administers mortgage-backed securities through the Common Securitization Platform (CSP), a cloud-native infrastructure created as a joint venture between Fannie Mae and Freddie Mac. The CSP powers the issuance and administration of 71% of all mortgage-backed securities in the U.S. market, processing trillions of dollars in securities annually.
The platform operates critical financial market infrastructure that connects the secondary mortgage market to investors worldwide. In 2023, the company implemented an Active/Active distributed architecture across AWS regions designed for platform resiliency and zero-data-loss operation. The technical foundation emphasises cloud-native development, large-scale securities processing, and distributed system reliability.
Established in 2013, Common Securitization Solutions operates as essential infrastructure for the U.S. housing market, standardising securitisation processes across the two largest government-sponsored enterprises and supporting the mortgage investments held by millions of American households and global investors.
