Anytime, anywhere user access is a priority

Zero trust has been around for more than 10 years. But, as users work from anywhere, and apps move from inside the data center to outside the network perimeter, network and security teams have had to shift their focus. It’s no longer about securing a network. It’s about protecting users, devices, and business resources.

Verify Identity

Instead of trusting an IP address, establish the identity of the user and device using an identity provider (IDP) first

Set Contextual Policies

Define access policies based on user, device posture, location, and apps, and rely on a cloud service to enforce them

Improve Visibility and Adapt

Use logs to determine which users are accessing which apps, and auto-adapt based on any changes in context

ZTNA as defined by Gartner

ZTNA provides controlled access to resources, reducing the surface area for attack. The isolation afforded by ZTNA improves connectivity, removing the need to directly expose applications to the internet. The internet becomes an untrusted transport and access to applications occurs through an intermediary. The intermediary can be a cloud service controlled by a third-party provider or a self-hosted service.
