Introduction to FGT_400E_BP-v7.0.15.M-build0632-FORTINET.out
This firmware release (build 0632) delivers critical security enhancements and operational optimizations for the FortiGate 400E BP (Branch-Premises) series appliances. Designed for distributed enterprise networks, the update focuses on maintaining threat prevention efficacy while addressing 4 high-severity vulnerabilities identified in Q1 2025.
Exclusive to the 400E BP hardware variant, this maintenance release supports configurations migrated from FortiOS 7.0.12-7.0.14 and serves as a bridge between the 7.0.x and upcoming 7.2.x firmware branches. The “M” designation indicates prioritized security updates for environments requiring FIPS 140-3 compliance.
