Zscaler Private Access (ZPA) is a new approach to secure remote access that’s based on a software-defined perimeter (SDP) model. A fully cloud-delivered service, ZPA ensures that only authorized users have access to specific private applications by creating secure segments of one between a user and an app. More than a VPN alternative, ZPA eliminates the attack surface and enables you to support multicloud environments simply and securely.

Other organizations begin by securing internal apps in the data center and cloud while providing access for remote users without VPN technology. Learn more on our Plans and Pricing page.
