Why Firewalls Won’t Matter In A Few Years:
1. Firewalls operating at 10G or more are not cost effective. Vertical scaling of performance costs more than the services are worth.
2. At 100G, a firewall has less than 6.7 nanoseconds to “add value” before they impact service delivery
3. You can’t use firewalls to secure East/West data flows in the network.
4. Application Security is the answer to this problem. Security is about secure software engineering.
