I like to install Palo Alto mainly on the data center side to have visibility into all VLANs. That gives full visibility into the core.
Palo Alto Networks NG Firewalls reduce malware and phishing attacks by 60 to 70 percent while providing robust security features such as application and URL filtering, threat prevention, and WildFire. They offer scalability and seamlessly integrate with third-party tools but face criticism for high pricing, complexity in setup, and limited technical support. While integration capabilities and scalability require enhancements, their scalable architecture separates management and data processes effectively, ensuring excellent application detection and granularity.
