Introduction to FGT_3601E-v7.0.15.M-build0632-FORTINET.out
This firmware delivers FortiOS 7.0.15 M-Release for FortiGate 3601E next-generation firewalls, designed for large enterprises and data centers requiring hyperscale threat protection and multi-gigabit throughput. Released as a security-critical update in Q2 2025, it addresses 16 CVEs while optimizing hardware resource allocation for FG-3601E appliances with 100G interfaces.
The software supports FG-3601E hardware platforms running FortiOS 7.0.x, featuring dual NP7 security processors and hardware-accelerated TLS 1.3 decryption. Build 0632 resolves critical memory management errors identified in previous 7.0.15 iterations and introduces ASIC-level optimizations for high-density environments.
Key Security and Performance Enhancements
