The short version

  • Only OPNsense has a free tier, so it costs nothing to try first.
  • Each has a real cost: Norton 360 device limit of 3 devices on Standard plan; higher tiers needed for family with multiple devices; OPNsense throughput depends entirely on hardware you selected yourself, and intrusion prevention at multi-gigabit rates will saturate a machine that handled plain firewalling fine, with no vendor sizing commitment to fall back on.
  • They diverge on capability: Norton 360 covers Real-time threat protection, OPNsense covers Stateful firewall on pf.
  • Prices and features above were last checked on 30 August 2026.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Norton 360

  • Device limit of 3 devices on Standard plan; higher tiers needed for family with multiple devices
  • Parental controls unavailable on Standard plan, requiring purchase of separate Norton Family app
  • No HIPAA compliance or BAA support for regulated industries
  • Exploit Prevention works only on Windows devices, not available for macOS
  • Limited account recovery options if master password is forgotten

OPNsense

  • Throughput depends entirely on hardware you selected yourself, and intrusion prevention at multi-gigabit rates will saturate a machine that handled plain firewalling fine, with no vendor sizing commitment to fall back on.
  • The weekly update cadence is good for security but means more change events than a team used to annual appliance firmware, and occasional regressions reach production installations.
  • FreeBSD underneath limits driver support compared with Linux, so recent network cards and some virtualisation drivers can be unsupported or slow.
  • The plugin ecosystem is uneven in quality; some plugins are maintained by a single contributor and can lag a major release, breaking a function you depended on.
  • Community support is a forum, so an outage at two in the morning on the free edition is your problem alone unless you bought the business subscription in advance.
