1. Introduction to vsigupdate_OS7.2.0_91.09632_FWAV.pkg
This firmware package delivers critical threat intelligence updates for FortiGate firewalls running FortiOS 7.2.0 or later. Designed to combat emerging network vulnerabilities, it integrates 12,500+ new intrusion prevention system (IPS) signatures and 34 advanced malware detection patterns validated by FortiGuard Labs’ global threat research network. The “91.09632” version identifier confirms cumulative security updates through Q1 2025, with backward compatibility for all 7.2.x firmware deployments.
Compatible with FortiGate 100F/200F/600F series appliances, this update meets PCI-DSS 4.0 and NIST 800-53 revision 5 compliance requirements. Released on 10/15/2024, it addresses 19 critical CVEs disclosed in the NVD database since July 2024.
