Secure access to any resource on the internet with Tailscale. Based on WireGuard® technology, Tailscale is a networking solution that enables highly customizable, end-to-end encrypted, and Zero Trust-aligned connections between any resources across any infrastructure. Tailscale adds identity to the network layer, allowing you to manage access based on user identities, not just their IP addresses. This enables you to intuitively and flexibly define which users should have access to which services, leveraging existing accounts, groups, services, and subnet ranges. Tailscale transforms your existing network from an outdated centralized model to a modern, lightweight, and responsive mesh architecture, eliminating single points of failure and ensuring superior performance, scalability, and security for end-users, devices, and remote resources. Replace legacy VPNs, unify workloads across on-premise and cloud infrastructures, implement Zero Trust, and enable secure remote access—all while simplifying software-defined networking (SDN) and security operations. Deploy a zero-config VPN, securely access resources on any infrastructure, optimize network workflows for developers, and modernize enterprise networks with Tailscale. Tailscale is hardware-agnostic: you can choose hardware independently of networking decisions. Tailscale creates an overlay network on top of your existing infrastructure, allowing you to implement it gradually without replacing switches or making architectural changes. Tailscale supports over 100 technology integrations and dozens of identity providers, and is available on a wide range of platforms, including Apple macOS, iOS, and tvOS, Windows, Linux, and Android.
