Expert Analysis
The headline difference between the FPR1140 and FPR1150 is twofold: the 1150 delivers roughly 60–75% more inspected throughput, and it adds two 10G SFP+ interfaces that the 1140 simply does not have. For any deployment where the WAN, DMZ or inter-VLAN trunk could conceivably push beyond 1 Gbps — increasingly common even at mid-market sites with gigabit fibre — the 1150 is the only one of the pair that can carry that traffic at line rate on a single interface.
The 1140 is still a credible appliance for UK branch and smaller HQ deployments: 3.3 Gbps of FTD throughput with full NGIPS and 1.2 Gbps of TLS decryption comfortably covers a 100–250-user site running Microsoft 365, SaaS and typical north-south inspection. Its 400 VPN peers and 400K concurrent sessions are the practical ceiling, however, and active/standby is the only HA option — fine for branch resilience, less ideal where you want both nodes carrying load.
The 1150 lifts every meaningful number: 5.3 Gbps FTD, 6.1 Gbps NGIPS, 600K sessions, 800 VPN peers, 2.4 Gbps IPSec, and active/active HA in addition to active/standby. The 10G uplinks and doubled VPN peer count make it the better fit for a regional HQ aggregating branch IPSec tunnels or for a site where SSL inspection on Office 365 and web traffic is mandatory under an internal data-protection or NCSC-aligned policy.
Recommendation: pick the 1140 if you are sizing for a sub-300-user UK site with a 1 Gbps WAN, modest VPN concentration and no realistic 10G requirement on the horizon. Step up to the 1150 if you need 10G interfaces, expect to terminate more than ~400 VPN users, want active/active HA, or want headroom for TLS inspection growth over a 5-year refresh cycle — the relatively small price delta for the capability uplift is usually justified.
