Business Model
What each company does and how it makes money
Zscaler is a cloud-native security platform that provides secure internet and private application access without traditional network hardware. It generates revenue primarily through subscription fees for its Zero Trust Exchange platform — with its core Zscaler Internet Access and Zscaler Private Access solutions driving most of its business. The company's key advantage is its massive, globally distributed cloud architecture that processes over 300 billion daily transactions, creating significant scale and data advantages that competitors cannot easily replicate.
Oracle is a global enterprise software and cloud computing company that provides database management systems, enterprise applications, and cloud infrastructure services. It generates revenue primarily through cloud services and license support (~70% of total revenue) and cloud license and on-premise license sales (~20%), with hardware and services making up the remainder. The company's key moat is its entrenched position in enterprise database software—particularly with its flagship Oracle Database—which creates significant switching costs and lock-in for large corporate customers.
