High-performance network environments, such as large enterprises, headquarters, and data centers, frequently experience significant bottlenecks when processing high volumes of proxy traffic through their Secure Web Gateway (SWG) solutions. This performance limitation restricts necessary network scalability. PAN-OS ^® 12.1 solves this critical challenge by introducing support for the PA-5450 firewall. This enhancement specifically leverages the PA-5450's multi-CPU chassis architecture to deliver powerful improvements in throughput and scalability for high-traffic proxy deployments. This update ensures that users in demanding environments benefit fully from the enhanced capabilities of the Secure Web Gateway solution.
