Deployment of the NSX Distributed Firewall (DFW) must be configured in an NSX environment to ensure proper operation of a VM-Series firewall in order to secure east-west traffic. East-west traffic is the traffic that flows between applications or workloads within a network or a cloud environment. NSX environment is a private cloud environment that provides software-defined networking (SDN) and security for heterogeneous endpoints and workloads across multiple hypervisors, containers, bare metal servers, or clouds. NSX DFW is a feature that provides distributed stateful firewalling at the hypervisor level for every virtual machine (VM) in an NSX environment. Deployment of the NSX DFW must be configured in an NSX environment to ensure proper operation of a VM-Series firewall in order to secure east-west traffic by enabling features such as service insertion, policy redirection, service chaining, orchestration, monitoring, logging, and automation for VM-Series firewalls and Panorama on NSX environment. VMware Information Sources, User-ID agent on a Windows domain server, and device groups within VMware Services Manager do not need to be configured in an NSX environment to ensure proper operation of a VM-Series firewall in order to secure east-west traffic, as those are not required or relevant components for NSX integration.

The partition can be accomplished without editing the IP addresses or the default gateways of any of the guest VMs by creating a new virtual switch and using the VM-Series firewall to separate virtual switches using virtual wire mode. Then move the guests that require more security into the new virtual switch. A virtual switch is a software-based switch that connects virtual machines (VMs) in a VMware ESXi environment. A virtual wire is a deployment mode of the VM-Series firewall that allows it to act as a bump in the wire between two network segments, without requiring an IP address or routing configuration. By creating a new virtual switch and using the VM-Series firewall to separate virtual switches using virtual wire mode, the customer can isolate the group of VMs that require more security from the rest of the network, and apply security policies to the traffic passing through the firewall. The partition cannot be accomplished without editing the IP addresses or the default gateways of any of the guest VMs by editing the IP address of all of the affected VMs, creating a Layer 3 interface in the same subnet as the VMs and then configuring proxy Address Resolution Protocol (ARP), or sending the VLAN out of the virtual environment into a hardware Palo Alto Networks firewall in Layer 3 mode. Use the same IP address as the old default gateway, then delete it, as those methods would require changing the network configuration of the guest VMs or introducing additional complexity and latency.

DNS Security is the feature that provides real-time analysis using machine learning (ML) to defend against new and unknown threats. DNS Security leverages a cloud-based service that applies predictive analytics, advanced ML, and automation to block malicious domains and stop attacks in progress. Advanced URL Filtering (AURLF), Cortex Data Lake, and Panorama VM-Series plugin are not features that provide real-time analysis using ML, but they are related solutions that can enhance security and visibility.

CN-Series firewall is the software firewall that would help a prospect interested in securing an environment with Kubernetes. Kubernetes is a platform that provides orchestration, automation, and management of containerized applications. Kubernetes environment requires network security that can protect the inter-service communication from cyberattacks and enforce granular security policies based on application or workload characteristics. CN-Series firewall is a containerized firewall that integrates with Kubernetes and provides visibility and control over container traffic. CN-Series firewall can help a prospect interested in securing an environment with Kubernetes by inspecting and enforcing security policies on traffic between containers within a pod, across pods, or across namespaces in a Kubernetes cluster. KN-Series, ML-Series, VM-Series, and Cloud next-generation firewall are not software firewalls that would help a prospect interested in securing an environment with Kubernetes, but they are related solutions that can be deployed on different platforms or environments.

The two statements that apply to the VM-Series plugin are:

It can be upgraded independently of PAN-OS.

It enables management of cloud-specific interactions between VM-Series firewalls and supported public cloud platforms.

The VM-Series plugin is a software component that extends the functionality of the PAN-OS operating system to support cloud-specific features and APIs. The VM-Series plugin can be upgraded independently of PAN-OS to provide faster access to new cloud capabilities and integrations. The VM-Series plugin enables management of cloud-specific interactions between VM-Series firewalls and supported public cloud platforms, such as AWS, Azure, GCP, Alibaba Cloud, and Oracle Cloud. These interactions include bootstrapping, licensing, scaling, high availability, load balancing, and tagging. The VM-Series plugin cannot manage capabilities common to both VM-Series firewalls and hardware firewalls, as those are handled by PAN-OS. The VM-Series plugin cannot manage Panorama plugins, as those are separate software components that extend the functionality of the Panorama management server to support cloud-specific features and APIs.
