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.
Apple is a technology giant that designs and sells premium consumer electronics — most famously the iPhone — along with related software and services. It generates revenue primarily from hardware sales (roughly 80% of total) and a fast-growing services segment (around 20%) that includes the App Store, subscriptions, and licensing. Its key competitive advantage is a powerful ecosystem that locks users into its hardware, software, and services through seamless integration and high switching costs.
