What are the differences between zero trust and traditional VPNs?

Zero trust differs from traditional VPNs in securing remote connections by providing a more granular and continuous verification process for user identities and devices. While traditional VPNs typically grant access once users have been authenticated, zero trust goes beyond this by continuously monitoring and verifying users, devices, and their access permissions throughout the session. Zero trust also focuses on implementing strict access controls based on user roles, device health, and other contextual factors, rather than relying solely on network perimeter defenses like VPNs. This approach helps enhance security by reducing the potential attack surface and ensuring that only authorized users and devices can access specific resources.
