ExpressVPN vs OPNsense

ExpressVPN is a premium consumer VPN known for fast speeds, a large global server network, and a very easy setup, with an audited no-logs policy. It is a mainstream, polished choice.

OPNsense is an open-source firewall and routing platform built on FreeBSD, offering a stateful firewall for IPv4/IPv6, multi-WAN load balancing and failover, and hardware failover via the CARP protocol. It bundles multiple VPN options (IPsec, OpenVPN, WireGuard, Tinc), an intrusion prevention system powered by Suricata, and NetFlow-based traffic reporting, all managed through a web GUI. The core platform is free under a permissive BSD/MIT license and can run on anything from a fanless mini-PC to a rack appliance, including official OVA images for virtualization. A paid Business Edition adds a Web Application Firewall, extended threat-intelligence blocklists, centralized fleet management (OPNcentral), and training/e-book resources for organizations that need vendor-backed support.
