Intel to make Fortinet's next-gen firewall chip on Intel 4

Intel Corporation and Fortinet announced a strategic collaboration on July, 21, 2026, to develop the next-generation Fortinet Security Processor 6 (SP6), the custom silicon that will power Fortinet's FortiGate firewall appliances. The partnership marks a significant milestone for Intel's foundry business, as Fortinet is the first external customer publicly named to use Intel's advanced Intel 4 manufacturing process.

Under the agreement, Intel will contribute its expertise in chip design, advanced packaging, and manufacturing to the SP6 program. This expands a longstanding relationship between the two companies, combining Fortinet's two decades of experience designing purpose-built security processors with Intel's semiconductor production capabilities. The collaboration aims to deliver a highly integrated security processor capable of supporting increasingly sophisticated security services and performance demands.

The SP6 will be manufactured on the Intel 4 node, a process utilizing extreme ultraviolet (EUV) lithography that Intel had previously reserved for its own products. This makes Fortinet the first publicly disclosed customer for this manufacturing technology. While the...
