Introduction to FGT_60E_DSL-v7.2.2.F-build1255-FORTINET.out

This firmware package delivers ​​FortiOS 7.2.2 Feature Release (F-build1255)​​ for ​​FortiGate 60E DSL Series​​ appliances, released on March 11, 2025. Designed for small-to-medium businesses requiring DSL broadband security, it addresses 9 critical vulnerabilities while optimizing ADSL2+/VDSL2 modem performance. The update integrates with FortiManager 7.6.3+ for centralized policy management and FortiAnalyzer 8.4+ for threat analytics.

Exclusive to ​​FortiGate 60E DSL models (FG-60E-DSL)​​, this build resolves connectivity instability reported in remote branch deployments. IT administrators managing distributed retail networks should prioritize installation due to patched SSL-VPN exploits (CVE-2025-32756) and enhanced IoT device visibility.
