Palo Alto Certified Network Security Administrator Exam 2026

This course provides a comprehensive and practical foundation in modern network security, focusing on next-generation firewall technologies and real-world enterprise deployments. It is designed to help learners understand how application-aware security works beyond traditional port-based firewalls, enabling precise traffic control using application identification and user context.

You will explore the core architecture of modern firewalls, including control plane and data plane separation, single-pass processing, and parallel inspection for high-performance security enforcement. The course explains how firewall policies are evaluated, how least-privilege access is implemented, and how to design clean, maintainable security and NAT rules using reusable objects and groups. You will also gain a solid understanding of routing integration, high availability concepts, and centralized device management for scalable operations.

A major focus is placed on advanced security services such as App-ID for application visibility, Content-ID for deep threat inspection, URL filtering for safe web access, and decryption for inspecting encrypted traffic. You will learn how these technologies work together to prevent malware, block command-and-control traffic, stop data exfiltration, and enforce acceptable use policies. Best practices for deploying these features safely and efficiently are covered, including performance considerations and compliance-friendly configurations.

The course also addresses secure remote access using modern VPN solutions, detailing how gateways, portals, authentication methods, and split-tunneling options are used to provide consistent security for remote and mobile users. Practical guidance is included for initial device setup, licensing, updates, backups, and operational hardening to ensure a stable and secure baseline configuration.

By the end of this course, learners will be able to design, configure, and manage a robust firewall security posture for enterprise environments. It is ideal for network engineers, security administrators, and IT professionals who want to build strong fundamentals in next-generation firewall technologies and apply industry best practices for real-world security operations.
