NPU Processing in Fortigate

The NPU process is responsible for offloading certain networking tasks from the main CPU to dedicated hardware, such as packet forwarding, VPN encryption/decryption, and traffic shaping. This offloading helps improve performance and reduce the load on the main CPU.

NPU (Network Processing Unit) offload is a feature of Fortinet firewalls that allows certain network processing tasks to be handled by specialized hardware rather than the main CPU. This can improve the performance and efficiency of the firewall by allowing it to handle more traffic and perform complex tasks more quickly. Examples of tasks that can be offloaded to an NPU include packet filtering, VPN encryption/decryption, and network address translation (NAT).
