Introduction to FGT_81F-v7.0.15.M-build0632-FORTINET.out

This firmware package delivers critical network security enhancements for Fortinet’s enterprise-class FortiGate 81F Next-Generation Firewall, designed for mid-sized networks requiring 10Gbps threat inspection throughput. The 7.0.15.M build addresses 12 CVEs disclosed in FortiOS 7.0.x branches while optimizing the NP6XLite security processing ASIC’s operational efficiency.

Validated for production deployment on 2025-05-01, this release maintains backward compatibility with FortiManager 7.4.6+ for centralized policy orchestration and FortiAnalyzer 7.2.11+ for log correlation. The update meets compliance requirements for PCI-DSS 4.0 and ISO 27001 frameworks, particularly crucial for financial and healthcare sectors.
