The concept of Zero Trust is based on the assumption that any network is always hostile, and thus, any IT system, application, or user is constantly exposed to potential external and internal threats. This concept has gained popularity as a modern alternative to traditional perimeter-based security. An infrastructure designed around this model treats every user, application, or data source as untrusted and enforces continual verification by strict security, access control, and comprehensive auditing to ensure visibility and accountability of all user activities. Within Zero Trust, the concept of ZTNA (Zero Trust Network Access) plays a central role.

In the past, VPNs (Virtual Private Networks) were the most common solution to provide secure remote access. The COVID-19 pandemic forced the majority of corporate workforces to work from home for two years, leading to the current popularization of Work from Anywhere (WfA).

A fundamental difference between modern ZTNA and legacy VPN solutions is the separation of control and data planes, which can be set up in different locations, but still enable a single point of management and visibility across complex deployments. ZTNA solutions with their SaaS-based management tools provide significant advantages over traditional on-premises VPN solutions. These solutions are modern, more flexible and scalable alternatives to aging VPN infrastructures.
