Introduction to FGT_3300E-v7.2.3.F-build1262-FORTINET.out Software
The FGT_3300E-v7.2.3.F-build1262-FORTINET.out firmware is a critical security and performance update for FortiGate 3300E series next-generation firewalls, designed for enterprise data centers requiring hyperscale threat prevention and high-throughput network security. Released under FortiOS 7.2.3.F, this build addresses 21 CVEs while introducing hardware-accelerated threat detection powered by Fortinet’s fifth-generation NP7 ASIC technology.
Specifically engineered for the FortiGate 3300E platform, this firmware delivers 200Gbps+ threat inspection throughput and supports hyperscale SSL-VPN deployments. The release aligns with Fortinet’s Q2 2025 security advisory cycle, focusing on mitigating risks from historical vulnerabilities like FG-IR-24-015 (SSL-VPN out-of-bounds write) and FG-IR-23-097 (SSL-VPN heap overflow).
