Palo Alto Networks offers a full line of next-generation security appliances that range from the PA-200, designed for enterprise remote offices, to the PA-7050, which is a modular chassis designed for high-speed datacenters. Our platform architecture is based on our single-pass software engine and uses function-specific processing for networking, security, threat prevention, and management to deliver predictable performance. The same firewall functionality that is delivered in the hardware appliances is also available in the VM-Series virtual firewall, allowing you to secure your virtualized and cloud-based computing environments using the same policies applied to your perimeter or remote office firewalls.
