Introduction to FGT_3300E-v6-build6013-FORTINET.out.zip Software

The ​​FGT_3300E-v6-build6013-FORTINET.out.zip​​ firmware package delivers critical security updates and performance enhancements for Fortinet’s enterprise-grade FortiGate 3300E firewall series. As part of FortiOS v6.4.15 maintenance releases (网页8), this build specifically addresses 5 CVEs disclosed in Q1 2025 while optimizing hardware acceleration capabilities for distributed network environments. Designed for mid-sized data centers and campus networks, this release maintains backward compatibility with SD-WAN architectures and zero-trust security frameworks (网页6).

Compatibility is restricted to ​​FortiGate 3300E​​ hardware appliances, with build 6013 targeting organizations requiring CVE-2025-3287 mitigation (网页9). Although the exact release date isn’t documented publicly, version tracking indicates deployment readiness since March 2025 through Fortinet’s phased distribution model.
