What is ZTNA?

Zero Trust Network Access (ZTNA) is a security model that provides secure remote access to applications and services based on explicitly verified identity and context. It shifts away from the traditional VPN-based approach by granting access on a need-to-know basis, continuously verifying trust, and minimizing the attack surface. ZTNA is commonly used to secure access for remote workers, contractors, and third-party users to internal applications and data, enhancing security and reducing the risk of lateral movement within the network.
