Prospects interested in Palo Alto Networks virtualized next-generation firewalls (NGFWs) can achieve improved return on investment (ROI) through the following factors:

Reduced operational expenditures: Virtualized NGFWs reduce the need for physical hardware, lowering the costs associated with purchasing, maintaining, and managing hardware appliances. This also includes savings on power, cooling, and physical space requirements.

Independent Upgrade:

The VM-Series plugin can be upgraded independently of the PAN-OS version. This allows for flexibility in maintaining and enhancing the plugin without the need for a complete PAN-OS upgrade.

VM-Series firewalls provide advanced application-level security for web-server instances on AWS. These virtual firewalls leverage Palo Alto Networks’ next-generation firewall capabilities to offer features like application identification, threat prevention, and URL filtering, ensuring comprehensive security for web applications hosted on AWS.

To avoid split brain scenarios in an active-passive high availability (HA) pair deployment, the management interface can be used as the HA1 backup link. This ensures reliable communication between the HA pair and prevents both firewalls from assuming the active role simultaneously, which can happen if they lose connectivity with each other on the primary HA1 link.

To integrate a Palo Alto Networks VM-Series firewall with Azure Orchestration, an API Key is required. The API Key is used to authenticate and authorize the firewall to interact with Azure services, enabling automated management and orchestration of security policies and configurations.

User IP mappings:

Panorama can push user-to-IP mapping information to the NSX manager, enabling dynamic security policy enforcement based on user identity.

In AWS, VM-Series firewalls support only active-passive high availability (HA) configuration. This means that one firewall is active and processing traffic, while the other remains passive and takes over in the event of a failure. This design consideration ensures continuous availability and reliability of firewall services in the AWS environment.

Geneve (Generic Network Virtualization Encapsulation) is the protocol used for communication between VM-Series firewalls and a Gateway Load Balancer (GWLB) in AWS. Geneve provides a flexible encapsulation method and is specifically supported for integrating with AWS GWLB to ensure seamless traffic flow and security inspection.

For deploying VM-Series firewalls in high availability (HA), it is crucial to ensure that both firewalls in the HA pair have identical licenses and subscriptions to ensure feature parity and uninterrupted service during failover. Additionally, both firewalls must be deployed on the same type of hypervisor to ensure compatibility and proper synchronization of state and configurations between the active and passive units.

YAML File Structure:

The structure of a YAML file repository for managing configurations typically follows the order of Kubernetes/Deployment_Type/Environment. This hierarchy ensures that the configurations are organized logically, with Kubernetes-specific settings at the top level, followed by the type of deployment, and then the specific environment.
