Introduction to FGT_601E-v6-build0457-FORTINET.out.zip

This firmware release provides critical infrastructure protection updates for FortiGate 601E series next-generation firewalls, addressing 14 CVEs identified in Q1 2025 security audits. Designed for enterprise networks requiring PCI-DSS 4.0 and ISO 27001:2025 compliance, the build optimizes threat detection latency while introducing hardware-assisted TLS 1.3 decryption capabilities.

Compatible with FortiGate 601E hardware revisions 3.2+ and 602E HA clusters, this FortiOS 6.4.57 update maintains interoperability with FortiManager 7.6.3+ centralized management platforms. The release prioritizes mitigation of zero-day vulnerabilities affecting financial and healthcare sectors.
