Zero Trust Network Access (ZTNA) is an IT security solution that provides secure remote access to an organization’s applications, data, and services based on clearly defined access control policies. ZTNA differs from virtual private networks (VPNs) in that they grant access only to specific services or applications, where VPNs grant access to an entire network. As an increasing number of users access resources from home or elsewhere, ZTNA solutions can help eliminate gaps in other secure remote access technologies and methods.
