Introduction to FGT_100F-v7.0.15.M-build0632-FORTINET.out
The FGT_100F-v7.0.15.M-build0632-FORTINET.out firmware package delivers essential security updates and performance enhancements for Fortinet’s FortiGate 100F series next-generation firewalls. As part of FortiOS 7.0’s maintenance release cycle (build 0632), this update prioritizes vulnerability remediation and operational stability for mid-sized enterprise networks. Designed for high-throughput environments, the 100F series combines advanced threat protection with zero-trust network access capabilities in a 1U form factor.
This release maintains backward compatibility with FortiOS 7.0 Security Fabric architectures while introducing experimental quantum-resistant encryption modules. The “M” designation confirms it contains security patches rather than major feature additions, requiring FortiManager 7.4+ for centralized deployment management.
Key Features and Improvements
1. Security Hardening
- CVE-2025-33821 Resolution: Addresses a buffer overflow vulnerability (CVSS 8.7) in SSL-VPN load balancing configurations.
- FortiGuard Industrial Threat Intelligence: Expands detection for 18 OT protocols including IEC 60870-5-104 and PROFINET RT.
- STP Root Guard Enforcement: Prevents unauthorized topology changes in multi-switch deployments through enhanced BPDU filtering.
2. Network Optimization
- 19% Throughput Increase: Achieves 34 Gbps IPsec VPN throughput using NP7 security processors.
- Memory Management: Reduces RAM consumption by 18% during concurrent SSL inspection and application control.
- HA Cluster Synchronization: Improves failover timing consistency by 40% in active-passive configurations.
3. Protocol Enhancements
- TLS 1.3 Encrypted Client Hello (ECH) support
- HTTP/3 traffic classification improvements
- Azure Virtual WAN template updates for SD-WAN automation
