Zero Trust Network Access (ZTNA)

Zscaler Private Access provides Zero Trust Network Access (ZTNA) with a seamless, cloud-like user experience.

Secure, software-defined perimeter

Via a software-defined perimeter, ZPA enforces authentication prior to access, making apps invisible to the internet. ZPA ensures only authorised users have access to specific private applications by creating secure segments of one between individual devices and apps.

Secure cloud access

Secure cloud access

ZPA provides secure connectivity to private apps running across any hybrid or multi-cloud environment.

Merger & Acquisition (M&A) IT integration

Merger & Acquisition (M&A)

ZPA provides secure access without needing to converge networks / IP addresses, accelerating integration during M&A.

VPN alternative

VPN alternative

ZPA seamlessly connects remote users to internal apps without a VPN or placing users on the internal network.

How does ZPA work?

With ZPA, applications are never exposed to the internet, making them completely invisible to unauthorised users. ZPA enables applications to connect to users via inside-out connectivity versus extending the network to them. Users are never placed on the network.

Zero Trust Security Model

Zscaler Private Access benefits

With ZPA, users no longer have to think about which app they are accessing. It just works. Accessing apps across in both the data centre and public cloud (Azure, AWS and GCP) is simply fast, less complex and secure.

  • User Experience:
    Fast, direct access to apps, without a VPN.
  • Security:
    Users are never placed on-net, plus app segmentation for granular security.
  • Value:
    No hardware appliances (plus reduced bandwidth usage).
  • Simplicity:
    100% software and cloud based, consistent across all apps & devices.

Choose application segmentation, not network segmentation

With ZPA, enterprises no longer need to perform complex network segmentation. Admins have the granular control to decide who can access what, even down to the individual application and user level.

  • Create and define policy names.
  • Set different permissions levels for users & user groups.
  • Select the applications each policy is associated with.
  • Easily add new rules and policies for your users & applications.
