What is ZTNA?
Zero Trust Network Access is the technology that replaces traditional VPNs in a Zero Trust architecture by providing application-level access based on verified identity and device posture rather than broad network access. Where a VPN grants a remote user access to the entire corporate network once connected, ZTNA grants access only to the specific applications the user is authorized to use – and only after verifying their identity, device compliance, and context at the time of each request. This dramatically reduces the attack surface because a compromised user account or device can no longer be used to roam freely across the network. ZTNA is a critical building block for organizations enabling secure remote work and moving toward a full Zero Trust model.
