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 are known for robust security, offering application-based management and threat protection. They feature user-friendly setup, advanced threat prevention, and machine learning for attack prevention. Integration and scalability support various environments. Criticisms include high costs, slow support, complex licensing, and integration challenges with third-party services, with hardware upgrades needed for increased capacity. Despite these, they remain a leading choice for organizations prioritizing security and compliance.
