Zscaler's Large Deal Activity Surges: What's Driving This Momentum?

Zscaler, Inc. (ZS) is seeing strong momentum in large enterprise deals as organizations continue to modernize their cybersecurity infrastructure. Growing demand for Zero Trust security, AI-powered protection and platform consolidation is encouraging customers to sign larger, multi-year contracts. Zscaler delivered a record performance in the third quarter of fiscal 2026. The company closed its highest-ever number of annual contract value deals worth more than 1 million dollars for the fiscal third quarter. Annual recurring revenues increased 25% year over year to more than 3.5 billion dollars, while remaining performance obligations climbed about 30% to nearly 6.5 billion dollars. The expanding adoption of ZS' platform is a key driver behind these larger deals. More than 700 enterprise customers are now using Zscaler's Zero Trust Everywhere framework, up from more than 550 in the previous quarter. Customers are increasingly deploying multiple products, including Zero Trust Users, Zero Trust Cloud, Zero Trust Branch and AI Protect, instead of purchasing standalone security solutions. Z-Flex is also supporting deal growth. The flexible purchasing program generated more than 480 million dollars in total contract value during the quarter, up more than 60% sequentially. By allowing customers to activate additional products within existing agreements, Z-Flex is increasing upselling opportunities.
