Introduction to FGT_60E_DSL-v6-build1232-FORTINET.out

This firmware update addresses critical security vulnerabilities for FortiGate 60E DSL series firewalls, specifically designed for branch offices requiring integrated xDSL connectivity. As part of FortiOS 6.4.15 maintenance release (build 1232), it resolves 12 CVEs identified through FortiGuard Labs’ threat intelligence network while optimizing ADSL2+/VDSL2 modem performance.

The release enhances threat protection throughput to 1.5 Gbps with active UTM services, making it suitable for retail and small business environments. Official documentation confirms backward compatibility with FortiManager 7.2.3+ for centralized policy management.
