Palo Alto Networks Firewalls

The Palo Alto Networks next-generation firewall may be used in several capacities, including as an origination and termination point for
securely connecting a private data center to AWS via AWS Direct Connect. This is a natural extension of network perimeter protection. VMSeries also can be used to control inter-VPC traffic. Using a “hub and spoke” design as an example, a transit Virtual Private Cloud (VPC) acts as
the hub, and provides common functions such as domain name services, directory services, and firewall capabilities. Traffic between the
spoke VPCs must traverse the hub, where the VM-Series ensures only expected application flows are permitted. Unknown traffic patterns,
which may be indicative of malicious activity or threats, are blocked.
