What is Zero Trust Security?

Virtual Private Networks (VPN) - a technology with little development since the 1990’s - struggles to provide an acceptable balance of secure access and productive digital experiences.
Zero Trust Network Access (ZTNA), also called a Software-Defined Perimeter, addresses the shortcomings of VPN by creating 1-to-1 connections between the user’s device and the resources they need - just for the required duration - making everything else invisible and inaccessible.
