It helps protect against compromised accounts and the lateral movement of threats, especially in remote work and cloud service scenarios.<\/p>\n<h2>How does ZTNA differ from traditional network access?<\/h2>\n<p>Traditional models trusted users once they were inside the network perimeter. ZTNA treats all access attempts as potentially untrusted, whether they come from inside or outside the corporate network.<\/p>\n<h2>What does identity verification mean in ZTNA?<\/h2>\n<p aria-level=\"3\">Identity verification is the process of confirming a person or device is who they claim to be before access is allowed.
