Scale Your Costly Perimeter Firewalls, Don’t Buy More
If internet traffic was not encrypted, you would get 100% throughput. However, with 85% of the internet in North America encrypted, you will need 10x firewalls to get the same throughput.
NSS Labs says typical NGFWs experience up to 90% performance degradation with decryption. Which means if a firewall does 18 Gbps of throughput pre-decryption, you will need 10 firewalls to match the originally “promised” performance of 18 Gbps…that is if we assume no load balancers are used.
