Introduction to FGT_300E-v6.M-build2095-FORTINET.out Software

This firmware release targets Fortinet’s ​​FortiGate 300E Series​​ next-generation firewalls, designed for mid-sized enterprises requiring hybrid mesh firewall capabilities. Released in March 2025 as part of FortiOS 6.M’s extended support cycle (ESC), build 2095 addresses 9 CVEs while improving SSL-VPN session scalability by 25% compared to v6.4.11.

Compatible exclusively with 300E hardware appliances, it introduces refined ZTNA gateway configurations and enhanced SD-WAN orchestration for multi-cloud deployments. Network administrators prioritize this build for its backward compatibility with FortiManager 7.6.3 policies and optimized TLS 1.3 session resumption protocols.

Key Features and Improvements

  1. ​​Security Hardening​​

    • Mitigated ​​CVE-2025-1123​​ (buffer overflow in IPS engine) and ​​CVE-2025-0881​​ (improper certificate validation in SSL-VPN).
    • FortiGuard threat intelligence now detects 42% more fileless attack patterns via enhanced memory analysis.

  2. ​​Operational Efficiency​​

    • 18% faster BGP route convergence through NP6XLite ASIC optimizations.
    • Reduced CPU utilization by 12% during simultaneous deep packet inspection (DPI) and SSL decryption workloads.

  3. ​​Protocol & Compliance Updates​​

    • Added RFC 9414 (QUIC Version 2) traffic classification for granular application control.
    • Extended REST API endpoints for automated compliance reporting under NIST 800-53 Rev6.

Compatibility and Requirements

Supported Hardware Minimum FortiOS Version Required Storage
FortiGate 300E 6.4.11 64 GB SSD
