These devices would look at packets, network addresses, and ports to determine if data should be allowed through or blocked. Traditional firewalls acted as a sentinel that monitors traffic moving into, and sometimes out of, the network. ![]() The Difference Between Traditional Firewalls and Next-Generation Firewalls They can be found anywhere from an on-premise network edge to its internal boundaries, and can also be employed on a public or private cloud environment.

Next-generation firewalls, also known as second generation firewalls, protect organizations through advanced security features. In this post, we will explain what a next-generation firewall is and how to select one that delivers high-quality security and a great user experience. ![]() A next-generation firewall (NGFW) is the only type of firewall that provides the capabilities to protect modern businesses against emerging cyberthreats.īut not every NGFW is designed the same way.
