Introduction to FGT_401F-v7.0.11.M-build0489-FORTINET.out
This critical firmware update for Fortinet’s enterprise-class FortiGate 401F Next-Generation Firewall addresses 7 documented vulnerabilities while optimizing network performance for hyperscale data centers. As part of FortiOS 7.0.11.M branch (build 0489), it provides security hardening specifically designed for financial institutions and cloud service providers requiring PCI-DSS compliance.
The 401F model utilizes this update to enhance SSL/TLS 1.3 inspection capabilities and SD-WAN traffic prioritization algorithms. Engineered for environments requiring 40Gbps threat prevention throughput, the firmware leverages Fortinet’s NP7 security processing ASIC while maintaining backward compatibility with existing FortiAnalyzer configurations.
