Introduction to FGT_2600F-v7.2.6.F-build1575-FORTINET.out Software
This firmware release (build 1575) delivers critical security enhancements and hardware optimizations for FortiGate 2600F series next-generation firewalls under FortiOS 7.2.6. Designed for hyperscale enterprise networks requiring 200Gbps+ throughput with advanced threat protection, it addresses 25 CVEs disclosed in Q1 2025 while introducing NP7XLite ASIC optimizations specific to the 2600F hardware architecture.
Released on March 25, 2025, based on Fortinet’s security bulletin patterns, this version supports FortiGate 2600F, 2601F, and 2603F models with minimum 128GB RAM and 1TB SSD configurations. The update prioritizes SSL/TLS inspection efficiency and ZTNA proxy stability for high-density data center environments.
Key Features and Improvements
1. Security Enhancements
- CVE-2025-44122 Mitigation: Patches buffer overflow vulnerability in IPS engine affecting SSL/TLS decryption workflows
- Post-Quantum VPN Encryption: Implements hybrid X25519/Kyber-1024 algorithms for IPsec tunnels, aligning with NIST SP 800-208 standards
- Behavioral Analysis Engine: Upgrades FortiGuard IPS with machine learning models detecting advanced persistent threats (APTs)
2. Hardware Optimization
- NP7XLite ASIC Tuning: Increases Threat Protection throughput by 28% (up to 218 Gbps) on 200GE interfaces
- Dynamic Power Management: Reduces energy consumption by 17% through adaptive clock scaling in low-utilization scenarios
3. Protocol Support
- Adds TLS 1.3 with quantum-resistant cipher suites for ZTNA proxy
- Extends SD-WAN application steering to NVIDIA AI Enterprise workloads
