Private Access that Scales with Your App Catalog
Zscaler, Thursday, August 6th, 2026
Zscaler's ZPA Application Scaling raises the per-tenant application ceiling from about 6,000 to 100,000.
Zscaler Private Access Application Scaling lets organizations grow from roughly 6,000 to about 100,000 applications per tenant.
It achieves this by sending client devices a condensed parent-domain list instead of full application definitions.
Exact application identity and policy decisions are evaluated in the cloud when needed, with results cached locally.
The design removes a scaling constraint for enterprises with very large application catalogs.
