What kind of traffic does the NSX-T Firewall inspect?

The NSX-T Firewall is designed to provide security for both North-South and East-West traffic, making the choice of saying that it inspects both types of traffic the correct answer.

North-South traffic refers to the data flow between the internal data center and the external world, including communications going in and out of the network. On the other hand, East-West traffic is concerned with communications that occur within the data center itself, between virtual machines or workloads located in the same or different segments of the network.

By inspecting both North-South and East-West traffic, NSX-T ensures comprehensive security measures are in place, allowing organizations to enforce security policies on all data traffic, regardless of its direction. This holistic approach is critical, as internal threats can occur as frequently as external threats. Thus, effectively managing both types of traffic allows for better overall network security and compliance with organizational policies.
