Palo Alto Enterprise Product Summary
PA-1420 firewall throughput: 9.9 Gbps (per Corporate Armor/Palo Alto datasheet). 120G vs 200F data from netwisetech.ae comprehensive analysis and official Fortinet datasheets. All values “up to”.
FG-120G vs FG-200F
Very close. The 120G (FortiSP5) wins on NGFW (4.2 vs 3.5 Gbps) and new sessions (180K vs 135K). The 200F wins on concurrent sessions (3M vs 2M) and storage (480 GB vs 256 GB). Choose 120G for internet-facing gateways. Choose 200F for campus environments with more endpoints. The 120G is approximately 15% cheaper.
Palo Alto PA-1420
9.9 Gbps firewall throughput — significantly lower than both FortiGate models (27-28 Gbps). The PA-1420 matches 120G/200F on IPS/threat prevention throughput. At approximately $15,000+, the PA-1420 costs 3-4x more than equivalent FortiGate deployments.
Verdict
FG-120G for new deployments (better chip, cheaper). FG-200F for high-session environments. PA-1420 is premium-tier.
