Introduction to FGT_900D-v7.2.6.F-build1575-FORTINET.out Software
This firmware release (build 1575) delivers critical security updates and hardware optimizations for FortiGate 900D series next-generation firewalls under FortiOS 7.2.6. Designed for enterprise data center deployments requiring 100Gbps+ throughput with advanced threat protection, it addresses 24 CVEs disclosed in Q1 2025 while introducing NP6XLite ASIC enhancements.
Released on April 28, 2025, based on Fortinet’s firmware update patterns, this version supports FortiGate 900D, 901D, and 903D models with minimum 64GB RAM and 1TB SSD configurations. The update focuses on improving SSL/TLS inspection efficiency and ZTNA proxy stability for high-density network environments.
Key Features and Improvements
1. Security Enhancements
- CVE-2025-32760 Remediation: Patches heap overflow vulnerability in IPS engine affecting SSL/TLS 1.3 decryption workflows (CVSS 8.9)
- Quantum-Resistant Encryption: Implements hybrid X25519/CRYSTALS-Dilithium algorithms for IPsec VPN tunnels, compliant with NIST SP 800-208 standards
- AI-Driven Threat Detection: Upgrades FortiGuard IPS with behavioral analysis models identifying APT command-and-control patterns
2. Hardware Optimization
- NP6XLite ASIC Tuning: Increases Threat Protection throughput by 27% (up to 118 Gbps) on 100GE interfaces
- Dynamic Power Management: Reduces energy consumption by 14% through adaptive clock scaling in low-traffic states
3. Protocol Support
- Adds TLS 1.3 with post-quantum cipher suites for ZTNA proxy
- Extends SD-WAN application steering to VMware Tanzu workloads
