Palo Alto Networks PA-3400 Series ML-Powered NGFWs—comprising the PA-3440, PA-3430, PA-3420, and PA-3410—target high-speed internet gateway deployments. The PA-3400 Series appliances secure all traffic.

The world’s first ML-Powered Next-Generation Firewall (NGFW) enables you to prevent unknown
threats, see, and secure everything—including the internet of things (IoT)—and reduce errors with
automatic policy recommendations.
The controlling element of the PA-3400 Series is PAN-OS, the same software that runs all Palo Alto
Networks NGFWs. PAN-OS natively classifies all traffic, inclusive of applications, threats, and content,
and then ties that traffic to the user regardless of location or device type. The application, content, and user—in other words, the elements that run your business—then serve as the basis of your security policies, resulting in improved security posture and reduced incident response time.
