VPN alternatives, such as Remote Desktop Protocol and virtual desktops, software-defined wide-area networks (SD-WAN), and secure access service edge (SASE) solutions, have emerged to address the weaknesses of traditional virtual private networks (VPNs). However, many of these alternatives share similar challenges with VPNs, including security vulnerabilities, performance bottlenecks, and management complexities. Zero Trust Network Access (ZTNA) is a modern security framework that eliminates the weaknesses of legacy secure perimeter approaches like VPN by unifying access control for all users and resources no matter their location. ZTNA assumes that any network, device, credential, user, or resource could already be compromised, explicitly verifies every attempt to access a protected resource, and only grants the degree of access users need in each session. By replacing VPN's hub-and-spoke topology with direct tunnels, Twingate's solution creates software-defined perimeters around protected assets, granular access control rules are enforced on user devices before making any connections, and encrypted tunnels passing directly between user devices and protected resources improve performance dramatically. Twingate also offers a phased deployment approach, compatibility with CI/CD pipelines, and simple administrative tools to make replacing your VPN system easy and risk-free.
