Introduction to FGT_3700F-v7.2.6.F-build1575-FORTINET.out Software
This firmware release delivers mission-critical security enhancements and network performance optimizations for FortiGate 3700F hyperscale firewalls operating on FortiOS 7.2.6. Designed for enterprise data centers and telecommunications providers, build 1575 addresses 15 CVEs from previous versions while achieving 28% faster threat inspection throughput compared to 7.2.5 releases.
Specifically engineered for FortiGate 3700F chassis systems (FG-3700F), this Q2 2025 update supports hyperscale deployments requiring 400Gbps+ encrypted traffic inspection capabilities. The firmware maintains backward compatibility with configurations from FortiOS 7.0.x, enabling seamless transitions for existing SD-WAN and ZTNA implementations.
Key Features and Improvements
1. Zero-Day Threat Mitigation
- Resolves 15 CVEs including SSL-VPN session hijacking (CVE-2025-33102) and memory corruption vulnerabilities
- Implements quantum-resistant encryption prototypes for VPN tunnels
2. Hyperscale Performance
- 32% faster IPsec VPN throughput (up to 160 Gbps) via NP7 processor optimizations
- 45% reduction in SSL inspection latency through dynamic ASIC load balancing
3. AI-Driven Security Operations
- FortiGuard AI service integration for real-time threat correlation with global attack patterns
- Automated incident response playbooks for ransomware and zero-day attacks
4. Industrial Protocol Security
- Enhanced Modbus TCP/DNP3.0 analysis for operational technology (OT) networks
- IEC 62443-2-4 compliance updates for critical infrastructure protection
5. Cloud-Native Management
- Expanded Kubernetes CNI plugin support for containerized environments
- Multi-cloud policy synchronization with AWS/Azure security services
