Tailscale

Tailscale is a zero-config VPN that creates a secure mesh network between your devices, servers, and cloud instances. Built on the WireGuard protocol, it simplifies networking by using your existing identity provider (like Google or Microsoft) to authenticate users. Unlike traditional hub-and-spoke VPNs, Tailscale connects devices directly to one another whenever possible, reducing latency and improving speed. It is particularly popular among developers and IT teams for its 'MagicDNS' feature and ease of setup. Tailscale allows for granular access control lists (ACLs), making it easy to define who can access what on the network without managing complex firewall rules.
