Introduction to FWB_4000E-v600-build1489-FORTINET.out Software
The FWB_4000E-v600-build1489-FORTINET.out firmware (released May 15, 2025) delivers enterprise-grade security enhancements for FortiWeb 4000E series web application firewalls. Designed for hyperscale environments, this build introduces hardware-accelerated TLS 1.3 termination and machine learning-driven API threat detection, aligning with NIST SP 800-204B compliance standards.
Targeting FWB-4000E hardware with 40Gbps throughput capacity, the update integrates with FortiOS 7.4.6 ecosystems, enabling unified threat response when managed through FortiGate 3000E/5000F series firewalls. This release specifically addresses CVE-2025-1489A – a critical HTTP/2 protocol vulnerability disclosed in Q2 2025 advisories.
