Introduction to FGT_100F-v7.2.8.M-build1639-FORTINET.out
This maintenance release delivers FortiOS 7.2.8M for FortiGate 100F next-generation firewalls, addressing 11 CVEs while optimizing threat inspection throughput for SMB networks. Released under Fortinet’s quarterly security update cycle, build 1639 enhances compatibility with FortiManager 7.6.x centralized management systems and introduces hardware-specific performance tweaks.
Designed for environments requiring <150,000 concurrent connections, this version supports hybrid deployments combining on-premises security policies with FortiSASE cloud integrations. The 7.2.8M branch prioritizes stability over feature additions, making it ideal for organizations running critical services like SD-WAN and ZTNA.
