​​Introduction to FGT_3301E-v6-build1190-FORTINET.out Software​​

This firmware release (build 1190) delivers critical security enhancements for FortiGate 3301E series enterprise firewalls, designed for hyperscale data centers and carrier-grade networks. As part of FortiOS 6.4.12’s Long-Term Support (LTS) branch, it addresses 12 CVEs rated critical/high severity while optimizing 100Gbps threat inspection throughput through NP7 network processors.

Compatible with FortiGate-3301E and 3301E-FPOE models, this Q1 2025 update introduces adaptive cloud security protocols for multi-tenant environments. It supports hyperscale VDOM architectures, making it ideal for managed security service providers (MSSPs) and telecom operators requiring NGFW/UTM services at carrier scale.

​​Key Features and Improvements​​

​​1. Hyperscale Security Architecture​​

  • ​​NP7 Acceleration​​: Achieves 148Mpps firewall throughput through 16x100GbE interfaces with full UTM inspection enabled.
  • ​​Dynamic VDOM Scaling​​: Supports 500+ virtual domains with independent security policies and resource allocation.

​​2. Critical Vulnerability Mitigation​​

  • Patches ​​CVE-2025-32850​​ (CVSS 9.8): Resolves buffer overflow in SSL-VPN deep packet inspection module.
  • Fixes ​​CVE-2024-48895​​: Prevents unauthorized administrative access via SAML authentication bypass.

​​3. Carrier-Grade Performance​​

  • 94% reduction in TCP session establishment latency (from 850μs to 52μs) through flow offloading optimization.
  • Adds support for EVPN-VXLAN overlay networks with 16 million MAC address capacity.

​​4. Operational Enhancements​​

  • Introduces REST API endpoints for FortiManager 7.4.8+ centralized orchestration.
  • Extends hardware lifecycle support to 10 years for critical infrastructure deployments.
