Furthermore, NGFW comes with features such as Intrusion Protection Systems (IPS) and Deep Packet Inspection (DPI). As a result, these firewalls provide wide-arching control and visibility over the data that enters and exits your network. What Is a Next-Generation Firewall (NGFW)?Īn NGFW is an advanced firewall that uses static and dynamic filtering strategies to filter packets based on applications. Let’s move on to next-generation firewalls next. Many traditional firewalls also come with Virtual Private Network (VPN) capabilities. In other words, it only exercises control over the flow of packets in one or both directions. If any of these match with any banned IP addresses, ports, or protocols, the firewall raises an alarm. Specifically, it examines the state of the packet, source/destination IP address, port number, and protocol. It inspects the traffic that enters or exits a network. What Is a Traditional Firewall?Ī traditional firewall has limited capabilities when compared to an NGFW. But before going any further, let’s understand what these two types of firewalls are. Read on as I answer these questions and more in this article. So, what are these changes? How do the traditional and NGFW stack up against each other? How can you choose one over the other for your organization? Particularly, they need to protect from ransomware and man-in-the-middle (MITM) attacks. You have many types of firewalls to choose from, but in this article, I’ll highlight the differences between a traditional firewall and a next-generation firewall (NGFW).īecause attacks are becoming more sophisticated, firewalls also need to evolve. They filter all traffic and block data that meets the patterns of an attack. Essentially, they’re a barrier between your network and the internet. Firewalls are the first line of defense for any organization.
