Introduction to FGT_601E-v6-build6325-FORTINET.out Software
This firmware package delivers FortiOS 6.0.15 for FortiGate 601E series next-generation firewalls, addressing 19 security vulnerabilities while optimizing enterprise network operations. Released in Q4 2024, the update combines critical protocol hardening with SD-WAN performance enhancements specifically engineered for distributed branch deployments.
Designed for 601E hardware platforms (FG-601E, FGR-601E), this build introduces adaptive threat intelligence sharing between FortiGate devices and FortiAnalyzer log servers. The firmware supports models with 128GB SSD storage and dual WAN configurations, maintaining backward compatibility with FortiOS 6.0.12+ installations.
