Tailscale IoT VPN: Zero‑Trust Networking

Secure Remote Access   An engineer needs to troubleshoot a programmable logic controller (PLC) at a remote pumping station. The device sits behind a 4G cellular modem, has no public IP address, and its local network blocks inbound traffic. The engineer cannot reach it. This problem repeats daily across factories, warehouses, solar farms, and toll […]
