3-year cost calculator
Pre-filled for SonicWall → pfSense. Adjust every figure with your own numbers.
Every figure here is an illustrative estimate, not a vendor quote. Defaults are editable starting points compiled from public information; real, binding pricing comes from the vendor or an authorized distributor. See our methodology.
Recommended for your requirements: Recommended class: 1U mid-range (2–20 Gbps) — size to 10 Gbps NGFW (threat-protection) throughput and 3 Gbps TLS inspection (decryption reduces effective throughput ~50–70%), 2 Gbps IPSec VPN, ~2M concurrent sessions. Require: IPS, application control, URL filtering, anti-malware/sandboxing, and IPSec + SSL VPN.
All figures are illustrative and fully editable — adjust the cost-per-firewall and migration inputs with your own numbers. Not guaranteed vendor pricing (defaults reviewed May 2026). For a binding quote, use the request form below to reach an authorized distributor or partner.
