Compatible Devices:
- FortiGate 60F and 61F hardware models
- Requires FortiOS 6.0 or later for integration with FortiManager 7.0+
Version Details:
- Build Version: v6-build6575 (FortiOS 6.0.18 branch)
- Release Date: Q1 2025 (per Fortinet’s firmware lifecycle documentation)
Key Features and Improvements
This firmware delivers strategic upgrades across three operational pillars:
1. Critical Security Enhancements
- CVE-2024-21762 Mitigation: Patched a high-risk SSL-VPN heap overflow vulnerability (CVSS 9.8) enabling unauthenticated remote code execution. This resolves one of the most severe exploits disclosed in FortiOS history.
- TLS 1.3 Full Traffic Inspection: Enabled sub-5ms latency decryption of modern encrypted traffic via FortiSP5 ASIC acceleration, addressing compliance gaps in financial and healthcare sectors.
2. Hardware-Optimized Performance
- 40% Faster IPsec VPN Throughput: Achieved 1.2 Gbps throughput for remote workforce connectivity, leveraging FortiSP5 hardware acceleration.
- Memory Efficiency: Reduced RAM consumption by 28% during DPI operations, enabling sustained performance in environments with ≤4 GB memory.
3. Network Management Innovations
- SD-WAN Policy Automation: Simplified synchronization with FortiManager 7.0.8+ for dynamic path selection in multi-WAN deployments.
- Zero-Touch Provisioning (ZTP): Added REST API support for bulk deployment in distributed retail or branch networks.
