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.
