Thirty years ago, the corporate network was relatively simple. Security consisted of protecting applications inside the network and building a secure perimeter around them.
But then things changed. Applications began moving to the cloud, a network the enterprise does not control. Users expect to seamlessly work off-network and from any device, anywhere. Remote access VPNs worked well in the network-centric world, but in the age of cloud and mobility, where there are virtual perimeters around the user, device, and application, they lack applicability.
Today, private application access is shifting away from network-centric approaches to a user and apps centric one. This has led to the increased popularity of “zero trust” and the adoption of zero trust network access (ZTNA) services. Also known as software-defined perimeters (SDPs), ZTNA enables secure access to private applications by establishing connectivity from user-to-application based on a dynamic identity- and context-aware basis.
ZTNA is different to VPN in these 3 main ways:

See how Aster Group UK replaced its remote access VPN and enabled seamless, secure application access for both internal and third-party users with ZTNA.
