NethSecurity vs pfSense

NethSecurity is an OpenWrt-based unified threat management solution for small and medium-sized businesses. It combines firewall, multi-WAN, content filtering, deep packet inspection, intrusion prevention, and VPN capabilities, including IPsec, OpenVPN, and WireGuard. Multi-WAN can balance connections, while traffic shaping applies minimum and maximum bandwidth settings. Threat Shield blocks known malicious IP addresses using named blocklists and confidence scores. NethSecurity is an open-source project and is currently available only for x86-64 systems; minimum requirements are 1 vCPU/core, 1 GB RAM, 1 GB disk, and two Ethernet cards. Its optional Controller runs on NethServer 8 and manages multiple installations remotely. Without a subscription, it can register up to three community firewalls; with a valid subscription, there is no unit limit, but only subscribed firewalls can be registered. Nightly automatic cloud backup is subscription-only. A 30-day trial activates the Business plan, but commercial support cannot be requested during the trial. Professional support response time is one business day during specified Italian business hours, excluding Italian holidays.

pfSense is a free, open-source FreeBSD distribution for firewall and router functions, managed through a web interface. Its source code is distributed under the Apache 2.0 license, and a package system lets users add functionality. Documented network features include firewalling, routing, VLANs, multiple WAN connections, high availability, traffic shaping, and captive portal. VPN options include IPsec, OpenVPN, and WireGuard; OpenVPN documentation lists authentication through local users, LDAP, or RADIUS servers. Deployment options include hardware, virtual machines, and public cloud. The software is available in the AWS and Azure marketplaces, including their US GovCloud regions. Netgate publishes security advisories, accepts vulnerability reports through its Security Team, and sells global support for self-installed software and virtual deployments. The Community Edition is a free download; listed Plus support plans offer either a limited number of tickets or unlimited tickets. One installation constraint: the USB memstick installer overwrites the entire hard drive and does not support dual booting with another OS.
