Packet filtering, which ensures that incoming and outgoing packets are inspected before they are allowed to pass through.When we talk about ‘traditional’ firewall features, we’re essentially talking about the functions that preceded NGFWs – functions such as: The features of a traditional firewallĪ traditional firewall is designed to police the flow of traffic that goes in and out of a network, based on port, protocol, source address and destination address. It is, however, the most advanced form of firewall that is currently available – and therefore the most recent.
Next-generation firewalls (NGFWs) are, as you might expect, the more advanced of the two types, offering the most robust protection for business networks.īut what are the differences between traditional and NGFWs, and how do they benefit your business?īefore we get into the finer details, it’s important to clarify that next-generation firewalling is not a new concept, despite what its name suggests. The two most basic categories for enterprise-level firewalls are traditional and next-generation. They all share the same basic goal, but specific features, capabilities and levels of sophistication can vary enormously. The purpose of any business firewall is to protect the network against intruders and to safeguard systems and data.īut not all firewalls are created equal.
