VPNs tunnel private traffic over untrusted networks — site-to-site connects whole offices; remote access gives a virtual NIC to roaming users. IPsec (IKE + ESP) is classic at the gateway; SSL VPNs and WireGuard are common for endpoints. Split tunneling sends only corporate prefixes through VPN — saves bandwidth but can leak data if misconfigured.
