TailscalevsZeroTier

Tailscale addresses secure private networking. Its device-to-device WireGuard connections remove much of the usual VPN configuration work. Tailnets are particularly appealing for remote teams that need private access to internal tools. ACL design becomes important as more people, devices and services join. A quick personal setup should not be mistaken for a finished company-wide access policy.

ZeroTier addresses software-defined virtual networking. ZeroTier is compelling when geographically scattered machines need to behave like members of one private network. Its virtual-network approach is flexible across varied devices. Network membership and route configuration can be confusing when the environment grows. Administrators still need to understand how traffic travels.
