Choosing the Right Firewall Size for Your Organisation

Firewalls are rated by throughput and capacity. Picking the right size keeps your network fast without overspending.

What to measure

Consider your internet bandwidth, number of users, and which security features you'll enable — deep inspection and IPS reduce real throughput, so look at the firewall's 'threat protection' rating, not just its raw figure.

Plan for growth

Size for two to three years ahead, including more users, higher bandwidth and more enabled features. A firewall running near its limit drops performance and protection.
