Real-World Scenarios: When to Choose Which
The question that matters: “In what situation will I regret choosing A over B after 3 months?”
Tailscale meshes devices using WireGuard via DERP relays, enabling SSH access to on-prem servers from anywhere without opening firewall ports or maintaining a VPN gateway.
Tailscale ACLs define which devices and users can reach which services using tag-based policy, replacing complex AWS security group rules with human-readable access policy files checked into git.
Tailscale subnet routers expose CIDR ranges of on-prem networks to the tailnet, giving WireGuard-encrypted access to devices that cannot run the Tailscale client directly.
