1. Introduction to FGT_1000D-v6-build0200-FORTINET.out

This firmware package delivers critical security enhancements for FortiGate 1000D series next-generation firewalls operating on FortiOS 6.0. Designed as a maintenance release, it addresses vulnerabilities identified in SSL-VPN, web filtering, and intrusion prevention subsystems while maintaining compliance with enterprise security standards.

Compatible exclusively with FG-1000D hardware models manufactured between 2015-2018, build0200 extends the operational lifespan of legacy devices through targeted vulnerability remediation. The firmware preserves existing UTM configurations while implementing NIST-recommended cryptographic protocols. Though specific release dates aren’t documented in public advisories, version sequencing indicates Q3 2019 deployment under Fortinet’s extended support program.
