Zero Trust Network Access (ZTNA) provides secure remote access based on zero trust security principles, and in particular, the principle of least-privileged access. Under zero trust, users and devices are, by default, not trusted. Instead, ZTNA allows each user access to specific applications on a case-by-case basis, authenticated through pre-defined, role-based controls and contextual data such as IP address, location, or even time—without exposing other network resources to risk. Least privileged access grants authentication based on credentials and context. Users get only the granular access they qualify for based on identity, device, and location. More secure than a VPN, ZTNA can help safeguard your IT network by providing only the specific permissions that the user has been explicitly granted, while it helps maintain flexible and responsive connections with your digital systems, branch locations, remote workers, and trusted partners.
