​​Introduction to FGT_3601E-v6-build0335-FORTINET.out Software​​

The ​​FGT_3601E-v6-build0335-FORTINET.out​​ firmware is a critical security and performance update designed for Fortinet’s FortiGate 3601E series next-generation firewalls. Released as part of FortiOS 6.0.3, this build addresses vulnerabilities, enhances protocol stability, and optimizes hardware resource allocation for enterprise-grade network environments. Compatible exclusively with the FortiGate 3601E hardware platform, this firmware ensures compliance with modern cybersecurity standards while maintaining backward compatibility with legacy configurations.

Based on FortiOS 6.0.3’s architecture, this release focuses on mitigating risks identified in earlier builds, such as unpatched CVEs and protocol misconfigurations. While the exact release date is not publicly documented in the provided resources, its build sequence (0335) aligns with Fortinet’s Q4 2022 firmware distribution cycle for mid-range firewall appliances.
