01Zscaler's land-and-expand model drove $321 million of the $500 million revenue increase in the nine months ended April 30, 2026 from upselling additional subscriptions to existing customers, demonstrating that once deployed, customers deepen usage rather than churn, creating durable expansion revenue.

02Zscaler operates as an inline proxy sitting between every user and the internet, meaning all enterprise traffic must traverse its cloud — a deployment model that embeds the platform into network architecture and makes rip-and-replace operationally disruptive.

03Approximately 40% of the Forbes Global 2000 are already Zscaler customers, giving the company a footprint in the largest, most security-conscious enterprises that competitors must displace rather than greenfield-sell into.
