​​Introduction to FGT_3301E-v7.0.11.M-build0489-FORTINET.out.zip​​

This firmware release addresses critical security vulnerabilities and enhances operational efficiency for Fortinet’s FortiGate 3301E series appliances. Designed for hyperscale data centers and enterprise networks, version 7.0.11.M-build0489 resolves 12 CVEs identified in prior FortiOS 7.0.x releases while introducing ASIC-accelerated TLS 1.3 decryption capabilities.

Compatible exclusively with FortiGate 3301E hardware (model FG-3301E), this update aligns with Fortinet’s 2025 security roadmap to combat advanced persistent threats targeting SSL-VPN and management interfaces. The firmware supports FIPS 140-3 compliance requirements for government and financial sectors.

​​Key Features and Improvements​​

​​1. Critical Vulnerability Remediation​​
