Introduction to FGT_2200E-v6-build1637-FORTINET.out
This firmware package delivers FortiOS 6.4.3 for FortiGate 2200E Next-Generation Firewalls, designed to address critical infrastructure vulnerabilities while optimizing large-scale network operations. Released under Fortinet’s Q3 2024 security maintenance cycle, build 1637 resolves 12 documented operational issues and enhances threat detection capabilities for industrial control system (ICS) environments.
Exclusively compatible with FortiGate 2200E (FG-2200E) hardware appliances, this update improves interoperability with power industry-standard protocols like IEC 60870-5-104 and DNP3. The firmware maintains backward compatibility with configurations created in FortiOS 6.4.1 and later versions, making it suitable for mission-critical substation automation networks.
