![]() ![]() NGFWs, on the other hand, operate at the application layer of the protocol stack. ![]() However, their lack of visibility into the content of network packets leaves them blind to many modern threats. By inspecting the IP addresses and port numbers of inbound and outbound packets, they limit the types of traffic that enter and leave the protected network. Traditional firewalls operate primarily at the TCP and IP levels of the protocol stack. However, they do so at different levels of the TCP/IP network protocol stack. Traditional firewalls and NGFWs are both designed to identify and block malicious or unwanted traffic from crossing network boundaries. ![]() This internal security is essential when account takeover, supply chain, and similar attacks grant hackers a foothold within an organization’s network. By dividing the corporate network into zones and forcing cross-zone traffic to pass through an NGFW, an organization provides itself with multiple opportunities to detect and remediate threats before they reach their intended goals. An NGFW’s array of integrated network security controls makes it a robust first line of defense against these threats.Īdditionally, NGFWs can be used as part of a network segmentation strategy. However, traditional firewalls lack the in-depth network traffic visibility to identify and prevent these attacks. Today’s threat landscape consists of modern Gen V cyberattacks which are sophisticated and organized, automated attack campaigns that target multiple attack vectors using advanced tactics and techniques to gain access to corporate environments.īlocking these attacks at the network perimeter is essential to minimizing the potential risk to the organization. ![]()
