Next-gen firewall FAQs

What is the difference between UTM and next-generation firewall NGFW?

A next-generation firewall adds new functions to the traditional firewall tasks of blocking inbound connection requests. These include packet inspection, application layer data examination, threat intelligence, and intrusion detection measures. UTM stands for Unified Threat Management and this is a system that combines the activities of different security tools operating on a network. A firewall will be part of a UTM but it won’t include as many threat protection functions as a next-gen firewall.

Does NGFW have IPS?

IPS stands for “intrusion prevention system.” An IPS is an intrusion detection system (IDS) with added responses to shut down malicious activities. A firewall has IDS capabilities. You wouldn’t expect a firewall to detect a threat and then just let its traffic through and so you can be sure that the firewall will have playbooks to block intrusion. This makes a next-gen firewall an IPS system.

What layer does a NGFW use?

A next-generation firewall is an Application Layer tool, which is Layer 7. This is because a NGFW examines traffic across packets, so it is more than a Network Layer tool that would only be concerned with individual packets. It is also more than a Session Layer tool because it examines the contents of the packets. It is also higher than the Data Layer because the system deals with intent and function rather than just data, so it operates at the top layer of the OSI stack.
