WireGuard has replaced IPsec and OpenVPN in many production environments - but enterprise deployment requires careful planning. This article compares WireGuard against legacy VPN solutions on performance, key management, and auditability.

Includes configuration templates for Linux gateways, Windows clients, and monitoring via Prometheus exporters.
