The best choice depends on your organization's size, technical requirements, and budget.

Choose pfSense if zero licensing cost for Community Edition — all core features included free is your priority and cost-conscious organizations and technically skilled teams that want a powerful, customizable firewall without licensing costs, and home lab or SMB environments. Choose WatchGuard Firebox if all-in-one security suite simplifies procurement and licensing for SMBs matters most and small and mid-sized businesses and managed service providers (MSPs) that need all-in-one network security with simplified deployment and centralized cloud management.

pfSense starts at Community Edition: Free / pfSense Plus: Included with Netgate appliances or ~$129-$399/yr for virtual deployments / TAC support plans available (open-source (free) or appliance-bundled with optional support subscriptions). WatchGuard Firebox starts at Hardware from ~$600 (Firebox T25) to ~$25,000 (Firebox M5800) / Total Security Suite or Basic Security Suite annual subscriptions required (appliance purchase + annual security suite subscription). As always, the sticker price only tells part of the story. Factor in add-ons, implementation costs, and what's actually included at each tier.

It depends on how deeply WatchGuard Firebox is embedded in your stack. Most teams run both in parallel for a few weeks before cutting over. Check whether pfSense supports importing your existing configs or policies. That's usually the biggest time sink.
