Palo Alto NetworksNetwork Security

    PA-400 Series

    ML-Powered next-generation firewalls for branch offices and midsize businesses.

    The Palo Alto Networks PA-400 Series brings ML-Powered Next-Generation Firewall capabilities to distributed enterprise branch offices, retail locations, and midsize businesses. Built on PAN-OS with App-ID, a single-pass architecture, inline machine-learning threat prevention, and Cloud-Delivered Security Services, it delivers enterprise-grade security in a compact desktop form factor. Faltrox deploys, configures Zero Trust policy, and manages it as part of a secure network.

    Overview

    What PA-400 Series is

    The PA-400 Series is Palo Alto Networks’ entry-tier hardware firewall, extending the full ML-Powered NGFW to the branch, retail location, and midsize business. It runs the same PAN-OS software as the largest models, so a small site enforces the identical security policy and benefits from the same threat prevention as the enterprise core — just sized and priced for the edge.

    It identifies applications with App-ID, users with User-ID, and content with Content-ID in a single pass, applies inline machine learning to prevent threats in real time, decrypts and inspects TLS traffic, and subscribes to Cloud-Delivered Security Services (Advanced Threat Prevention, URL Filtering, WildFire, DNS Security). Automatic policy recommendations simplify Zero Trust, and management runs through Panorama or Strata Cloud Manager. Faltrox deploys the appliances, builds the policy, and operates them as managed branch defence.

    Subscribes to the full Cloud-Delivered Security Services suite.

    How it works

    The mechanism

    How the product moves from signal to protected state, step by step.

    1. 01

      Deploy

      A compact desktop appliance is placed at the branch edge and onboarded to Panorama or Strata Cloud Manager.

    2. 02

      Identify

      App-ID, User-ID, and Content-ID identify applications, users, and content in a single pass.

    3. 03

      Prevent

      Inline machine learning and Cloud-Delivered Security Services prevent known and zero-day threats in real time.

    4. 04

      Decrypt

      TLS decryption inspects encrypted traffic so threats cannot hide in encryption.

    5. 05

      Operate

      Faltrox builds the Zero Trust policy, maintains PAN-OS, and monitors the appliances as managed defence.

    Capabilities

    Key capabilities

    App-ID

    Identifies applications regardless of port, protocol, or evasion, as the basis of policy.

    ML-Powered Prevention

    Inline machine learning analyses and prevents threats in real time, not just by signature.

    Single-Pass Architecture

    Identification and inspection happen once per packet for performance and consistency.

    Cloud-Delivered Security Services

    Subscribes to Advanced Threat Prevention, URL Filtering, WildFire, and DNS Security.

    User-ID & Zero Trust

    Ties policy to user identity with automatic policy recommendations for least privilege.

    TLS/SSL Decryption

    Decrypts and inspects encrypted traffic so threats cannot hide in TLS.

    Compact Form Factor

    A desktop appliance sized and priced for the branch, retail, and midsize edge.

    Centralised Management

    Managed through Panorama or the cloud-based Strata Cloud Manager.

    Delivery

    You buy the outcome, not the console

    Managed by Faltrox

    Faltrox licenses, deploys, and tunes Palo Alto Networks PA-400 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

    01Does a branch firewall really run the same security as the enterprise core?

    Yes — the PA-400 Series runs the same PAN-OS software as the largest models, so it enforces the identical policy and threat prevention, just sized for the branch. That consistency is a core benefit: a small site is not a weaker link in the security architecture.

    02What is App-ID and why does it matter?

    App-ID identifies the actual application in traffic regardless of port, protocol, or evasion, so policy is written on applications and users rather than ports. It is the foundation of Zero Trust segmentation on the firewall.

    03Does it inspect encrypted traffic?

    Yes — it decrypts and inspects TLS/SSL traffic so threats cannot hide inside encryption, which is essential now that most traffic is encrypted. Faltrox configures decryption policy to balance visibility and privacy.

    04How is it managed across many branches?

    Through Panorama (on-premises/virtual) or Strata Cloud Manager (cloud), which manage the whole firewall estate from one place with shared policy — so many branch firewalls are operated consistently. Faltrox runs that management for you.

    05How does Faltrox operate it?

    We deploy the appliances, build the Zero Trust and threat policy, enable the Cloud-Delivered Security Services, maintain PAN-OS, and monitor them — delivering managed branch firewalling rather than hardware you configure yourself.
