Introduction to FortiOS_7.2.x Software
FortiOS 7.2.x represents Fortinet’s mid-term stable release branch for next-generation firewalls, delivering enterprise-grade security and network convergence capabilities. Officially launched in Q2 2022, this version introduced 300+ features focused on AI-driven threat prevention and hybrid network optimization. Designed for FortiGate 60F/80F/100F series and newer hardware, it supports up to 40 Gbps firewall throughput while maintaining backward compatibility with SD-WAN and ZTNA architectures.
The latest iteration (7.2.10) released in September 2024 addresses critical 2FA timeout bugs and memory management issues observed in previous builds. As a long-term support (LTS) candidate, it remains actively patched against emerging threats while avoiding feature bloat from newer 7.4.x/7.6.x branches.
Key Features and Improvements
AI-Powered Security
- FortiGuard In-line Sandbox: Real-time malware interception via NP7 ASIC acceleration, reducing encrypted threat dwell time by 65% compared to traditional methods
- Zero-Day Hunting: Integrated threat scripts automatically detect CVE-2024-55591-style auth bypass attempts via websocket protocol analysis
- OT/IoT Protection: Device fingerprinting isolates industrial control systems from lateral movement attacks
Network Convergence
- HTTP/3 Protocol Support: Full visibility into QUIC traffic for Google Workspace/Microsoft 365 applications
- SD-WAN Orchestration: Automated overlay network scaling with MOS scoring for VoIP/video quality monitoring
- 5G WAN Integration: Unified policy enforcement across 5G wireless and wired edge devices
Administration Enhancements
- Unified ZTNA Console: Single-pane management for Zero Trust Network Access policies across hybrid environments
- 2FA Session Fixes: Resolved RADIUS token expiration bugs affecting SSL-VPN users
- Memory Conservation: Reduced kernel panic risks in deployments with <4GB RAM through optimized buffer allocation
