About Zscaler
Zscaler, Inc. is an American cloud cybersecurity company founded in 2007 by Jay Chaudhry and K. Kailash. Operating the world's largest inline security cloud across 150+ global data centers, Zscaler processes over 400 billion daily transactions, securing distributed workforces and enterprise cloud workloads without relying on traditional hub-and-spoke corporate networks.
Zscaler created the Zero Trust Exchange platform, replacing legacy corporate VPNs and perimeter security appliances. By connecting authenticated users directly to authorized applications—rather than connecting them to the underlying corporate network—Zscaler eliminates lateral threat movement and vastly reduces enterprise attack surfaces.
