Zones in a Palo Alto NGFW are central to network segmentation, allowing administrators to define how traffic flows between different parts of the network. Security policies are enforced based on the source and destination zones, enabling precise control and reducing the attack surface by restricting unnecessary communication between network segments. This approach enhances security by allowing granular policy enforcement tied to logical network segments rather than just interfaces or IP addresses, making it more difficult for threats to move laterally within the environment.

CN-Series is the containerized NGFW for Kubernetes environments, and VM-Series is the virtualized firewall for cloud and virtualization platforms. Both management platforms support centralized policy and device management for these Next-Generation Firewall products.

An ALG is designed to inspect and modify the payload of application-layer protocols (like SIP, FTP, etc.) to manage dynamic port allocations and session information.
Application Layer Gateways (ALGs) inspect the payload of certain protocols to dynamically manage sessions that use dynamic port assignments. By modifying payloads, the ALG ensures that NAT and security policies are correctly applied.

Host Information Profile (HIP) checks are used in GlobalProtect to collect and evaluate endpoint posture (OS, patch level, AV status) to enforce granular security policies for remote users.
The HIP feature collects information about the host and can be used in security policies to enforce posture-based access control. This ensures only compliant endpoints can access sensitive resources.
This enables fine-grained, context-aware access decisions beyond user identity alone.

SD-WAN solutions optimize application experience and provide secure, dynamic connectivity across distributed locations by leveraging real-time path metrics (latency, jitter, loss).
By implementing SD-WAN, traffic is routed intelligently based on real-time network performance metrics. Zone protection profiles ensure security while maximizing application performance.
Key advantage:
Secure connectivity and best user experience across campuses and branches.
