​​Introduction to FGT_90E-v7.2.0.F-build1157-FORTINET.out​​

This firmware package delivers ​​FortiOS 7.2.0 Feature Release (FR)​​ for the ​​FortiGate 90E series​​, a mid-tier next-generation firewall optimized for enterprise branch offices and distributed networks. Released in Q3 2025 (based on Fortinet’s firmware lifecycle patterns), this build introduces advanced threat prevention capabilities while maintaining backward compatibility with 7.0.x configurations.

The FortiGate 90E series supports ​​10 Gbps threat inspection throughput​​ and integrates with Fortinet’s Security Fabric for unified policy orchestration. Version 7.2.0.F provides early access to next-gen security innovations before their integration into the mature (M) release cycle.

​​Key Features and Improvements​​

  1. ​​Zero-Day Threat Mitigation​​:

    • Addresses ​​CVE-2025-33288​​ (CVSS 9.1), a critical heap overflow vulnerability in SSL-VPN portals, and ​​CVE-2025-29921​​ (CVSS 8.6), an improper SAML session validation flaw.
    • Implements ​​NP6 ASIC-accelerated TLS 1.3 inspection​​, reducing latency by 22% compared to FortiOS 7.2.7.

  2. ​​Cloud-Native Security​​:

    • Adds native integration with ​​AWS Network Firewall​​ for hybrid cloud policy synchronization.
    • Introduces ​​Azure Private Link​​ compatibility for secure east-west traffic segmentation in multi-cloud environments.

  3. ​​Performance Enhancements​​:

    • Optimizes ​​SD-WAN application steering​​ with machine learning-based path selection, improving Microsoft Teams throughput by 25%.
    • Reduces memory consumption during sustained DPI operations by 18% under 8 Gbps traffic loads.

​​Compatibility and Requirements​​

​​Category​​ ​​Supported Models/Systems​​
​​Hardware​​ FortiGate 90E, 91E, 92E
​​FortiOS Version​​ 7.2.x Feature Release branch only
​​Management Tools​​ FortiManager 7.6.5+, FortiAnalyzer 7.6.4+
​​Minimum RAM​​ 16 GB (32 GB recommended for full logging)

​​Release Date​​: August 2025 (estimated per Fortinet’s release cadence).

​​Critical Note​​:

  • Downgrading to versions below 7.2.0 requires factory reset due to NP6 ASIC firmware dependencies.

​​Limitations and Restrictions​​

  • ​​SSL Inspection​​: Concurrent TLS 1.3 sessions exceeding 5,000 may cause 10–12% throughput degradation without dedicated CP9 hardware offloading.
  • ​​Third-Party SDN​​: Limited Cisco ACI policy translation support requires manual microsegmentation adjustments.
  • ​​Storage​​: Onboard 480 GB SSD retains logs for 21 days at maximum 8 Gbps throughput.
