Palo Alto Networks produced the world's first Next Generation Firewall in 2007. These next generation firewalls secure businesses with a prevention-focused architecture and integrated innovations that can be easily deployed and used.

The Next Generation Firewall is a third generation firewall technology that is built by combining a traditional firewall with other network device filtering functionalities. These firewalls detect known and unknown threats, even those included in encrypted traffic, by leveraging intelligence generated across customer deployments.

The National Institute of Standards and Technology (NIST) 800-10 has divided firewalls into three basic types:

• Packet Filters - check incoming and outgoing traffic by creating a checkpoint at a traffic router or switch.
• Stateful Inspection - combines packet inspection technology and TCP handshake verification for enhanced protection.
• Proxys (or Application Level Gateways or Firewalls) - operate at the application layer and works by establishing a connection to the traffic source and inspecting the incoming data packet.

There are two more types of firewalls that are currently available:

• Circuit-Level Gateways - verify the Transmission Control Protocol (TCP) handshake which is designed to check that the packet session is legitimate.
• Next-Gen Firewalls - include architectures such as deep-packet inspection, TCP handshake checks and surface level packet inspection.

Yes, Palo Alto Networks firewall is a Stateful firewall. Palo Alto Networks is the principal developer for the Stateful Inspection Firewall and the first Intrusion Prevention System. Stateful Firewall technology involves the inspection of traffic passing through the firewall by matching it against a session. Each session is later matched against a security policy.

Firewalls work like filters between computers and the Internet. They are designed to stop unauthorized access to or from a private network. All messages entering or leaving the intranet pass through a firewall to ensure that an unwanted message doesn’t get transferred.
