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.

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.

Reduced time to deploy: Virtual NGFWs can be quickly deployed in various environments, such as public clouds or virtualized data centers, compared to the time-consuming process of installing physical hardware. This agility allows organizations to respond faster to security needs and market demands.

In a CN-Series (Cloud Native) environment, protecting communications between Docker containers is crucial. CN-Series firewalls are designed to provide advanced firewalling capabilities within containerized environments:

Firewalling: The CN-Series firewall provides Layer 7 visibility, allowing for application-layer security policies and protections. It ensures that all inter-container traffic is inspected, filtered, and secured according to the defined security policies. This includes blocking malicious traffic, preventing unauthorized access, and providing micro-segmentation within the Kubernetes clusters.

OpenShift:

The CN-Series firewall supports deployment in Red Hat OpenShift environments. OpenShift is a Kubernetes-based container platform that provides a comprehensive solution for container orchestration.
