In the context of Palo Alto Appliances, what does the term "Virtual System" refer to?

The term "Virtual System" in the context of Palo Alto Appliances refers to a logical system that enables multiple virtual firewalls to operate on a single physical device. This approach is crucial for organizations that need to segment different environments or applications without deploying additional hardware. By creating virtual systems, a single physical firewall can manage multiple network segments, each with its own distinct security policies, user access controls, and routing capabilities. This virtualization not only optimizes hardware usage but also simplifies management and reduces costs associated with maintaining multiple physical devices.

The benefits include the ability to host different customers or departments independently, providing customized threat protection and performance tuning according to the specific needs of each segment. This flexibility serves environments such as multi-tenant data centers or large enterprise networks, making it a powerful feature of Palo Alto's solutions.
