Yes, Zero Trust Network Access (ZTNA) can replace traditional VPNs in many cases. Unlike VPNs, which provide broad access to an entire network, ZTNA grants access only to specific applications or resources based on the user's identity, device health, and context. This reduces the attack surface and minimizes the risk of lateral movement if credentials are compromised. Additionally, ZTNA provides better scalability, performance, and security in cloud-centric environments compared to VPNs, making it an ideal replacement for organizations moving toward a Zero Trust security model.
