Network SecurityPA-400R Series
The world’s first ruggedized ML-Powered NGFW, for industrial and OT environments.
The Palo Alto Networks PA-400R Series is the world’s first ruggedized ML-Powered Next-Generation Firewall — built to secure industrial and harsh environments where standard appliances cannot survive. It brings the full PAN-OS NGFW, inline machine-learning threat prevention, and Cloud-Delivered Security Services to OT, utilities, transportation, and manufacturing. Faltrox deploys and manages it as the security edge for industrial networks.
Overview
What PA-400R Series is
Industrial and operational-technology environments — utilities, manufacturing, transportation, energy — face the same cyberthreats as IT but run in conditions (temperature extremes, vibration, dust) that destroy standard appliances, and they historically lacked purpose-built next-generation firewalls. The PA-400R Series is the world’s first ruggedized ML-Powered NGFW, closing that gap.
It secures industrial networks with the full PAN-OS NGFW — App-ID (including OT/ICS application awareness), inline machine-learning threat prevention, TLS decryption, and Cloud-Delivered Security Services — in a hardened, fanless chassis rated for harsh environments. That lets OT networks be segmented and protected to the same standard as IT, rather than left as a soft target. Faltrox deploys it into industrial environments, designs OT segmentation, and operates it as managed industrial defence.

How it works
The mechanism
How the product moves from signal to protected state, step by step.
- 01
Deploy
A ruggedised, fanless appliance is placed in the industrial environment where standard hardware could not survive.
- 02
Identify
App-ID recognises IT and OT/ICS applications and protocols to inform accurate industrial policy.
- 03
Segment
Zero Trust segmentation isolates OT zones and controls IT/OT crossover to contain threats.
- 04
Prevent
Inline machine learning and Cloud-Delivered Security Services prevent threats to industrial systems.
- 05
Operate
Faltrox designs the OT segmentation, maintains PAN-OS, and monitors the industrial edge as managed defence.

Works with
Part of the platform
Palo Alto Networks products this pairs with, and the Faltrox services that operate it.
Delivery
You buy the outcome, not the console
Managed by Faltrox
Faltrox licenses, deploys, and tunes Palo Alto Networks PA-400R Series for your environment, then runs it as part of a managed service, so you get the protection without staffing another security console.
FAQ
Common questions
01Why does OT need a ruggedized firewall?
Operational-technology environments run in conditions — temperature extremes, vibration, dust — that destroy standard appliances, so they historically lacked purpose-built next-generation firewalls and were left as soft targets. The PA-400R is the first ruggedized ML-Powered NGFW, letting OT be protected to the same standard as IT.
02Does it understand industrial protocols?
Yes — App-ID includes awareness of OT and ICS applications and protocols, so policy can be written accurately for industrial traffic rather than treating it as opaque. That is essential for meaningful segmentation and threat prevention in OT.
03Can it segment IT from OT?
Yes — Zero Trust segmentation isolates OT zones and tightly controls IT/OT crossover, which is one of the most important controls for containing threats that would otherwise move from a compromised IT network into industrial systems.
04Is it managed separately from our IT firewalls?
No — it is managed through the same Panorama or Strata Cloud Manager as your IT firewalls, so OT and IT security are operated consistently from one place. Faltrox runs that unified management.
05How does Faltrox operate it?
We deploy the ruggedised appliances into your industrial environment, design the OT segmentation and policy, maintain PAN-OS, and monitor the industrial edge — delivering managed OT/industrial network defence.
