About the Company

PayPal is the world's largest online payment system

PayPal is the world’s largest online money transfer, billing and payments system. It owns the PayPal, Venmo, iZettle, Xoom, Braintree, and Paydiant brands. By leveraging technology to make financial services and commerce more convenient, affordable, and secure, the PayPal platform is empowering more than 325 million consumers and merchants in more than 200 markets to join and thrive in the global economy.


Scaling a fraud prevention solution with 32% annual data growth

PayPal’s fraud rate, while well below the industry average, still gives them over 1 billion dollars a year of expsosure. They need to process and analyze more data, faster while minimizing end-user friction. On the back-end, their fraud management platform merges data from customer enrollments, payments, invoicing preferences, and profile data.

Real-time decisioning
Needed to quickly process and analyze data to identify emerging fraud patterns in under 200 milliseconds.
Requirement to grow from 3.5 transactions per second to 7 million transactions a second.
Data scale challenges included hundreds of petabytes.

With its high-performance NoSQL database, Aerospike is built explicitly to run on flash and Persistent Memory (PMem), not DRAM, while consistently delivering speed at scale. Here’s what Aerospike was able to do for PayPal:
