Palo Alto Enterprise Product Summary
FG-80F IPS is 2.6 Gbps per official Fortinet datasheet. XGS 136 firewall is 11.5 Gbps, IPS 4 Gbps, threat protection 1 Gbps per Sophos datasheet. All values “up to”.
The G-Series Advantage
FG-70G with FortiSP5 delivers 2.5 Gbps IPS — significantly better than the transitional FG-70F (1.4 Gbps). The FG-80F has the highest IPS in the F-series at this tier (2.6 Gbps). The FG-70F is a transitional model best avoided.
Palo Alto PA-460 vs Sophos XGS 136
PA-460: 12.6 Gbps firewall, 1.9 Gbps IPS. XGS 136: 11.5 Gbps firewall, 4 Gbps IPS (leading on IPS). FortiGate FG-80F: 2.6 Gbps IPS, 6.5 Gbps VPN — best VPN throughput in class.
Verdict
FG-70G for 25-50 users. FG-80F for 50-80 users needing 10 GE ports with higher IPS (2.6 Gbps). XGS 136 leads on raw IPS but Sophos threat protection is lower.
