Introduction to FGT_2200E-v6-build1263-FORTINET.out.zip

This firmware update delivers critical security enhancements and system optimizations for FortiGate 2200E next-generation firewalls operating in enterprise edge networks. Addressing 14 CVEs disclosed in Q2 2025, build1263 specifically mitigates vulnerabilities in SSL/TLS inspection modules while maintaining compatibility with hybrid mesh firewall architectures.

Designed exclusively for FortiGate 2200E hardware (FG-2200E), this release aligns with FortiOS 6.4.15 under Fortinet’s firmware versioning framework. The update package provides extended support for legacy deployments requiring FIPS 140-3 validated cryptographic operations in regulated industries.
