Are next-generation firewalls legacy technology?

Network World

A few years ago, next-generation firewalls (NGFWs) came out of nowhere to become a network security staple. These devices combined traditional L3/L4 packet filtering with deep packet inspection, IPS, and other network security services along with knowledge about users and applications. This broad functionality packaging changed the network security paradigm—everyone needed, or at least wanted a NGFW at the perimeter or within the internal network.

Fight firewall sprawl with AlgoSec, Tufin, Skybox suites

Network World

New and innovative security tools seem to be emerging all the time, but the frontline defense for just about every network in operation today remains the trusty firewall. They aren’t perfect, but if configured correctly and working as intended, firewalls can do a solid job of blocking threats from entering a network, while restricting unauthorized traffic from leaving. For admins trying to configure firewall rules, the task can quickly become unmanageable.
