Introduction to FGT_3300E-v7.4.0.F-build2360-FORTINET.out
The FGT_3300E-v7.4.0.F-build2360-FORTINET.out firmware package delivers FortiOS 7.4.0 for FortiGate 3300E next-generation firewalls, addressing 9 critical CVEs while optimizing enterprise data center network performance. Released on May 9, 2025, this update enhances Fortinet’s Security Fabric integration with improved threat correlation across hybrid cloud environments.
Engineered for the FortiGate 3300E series, this build (2360) resolves vulnerabilities in SSL-VPN services and web interface subsystems. Network architects managing high-traffic data centers or multi-tenant infrastructures will benefit from its upgraded threat prevention engine and enhanced virtual domain (VDOM) scalability.
Key Features and Improvements
1. Security Enhancements
- CVE-2025-21874 Remediation: Patches a buffer overflow vulnerability (CVSS 9.1) in IPsec VPN services that permitted unauthenticated remote code execution via malformed IKEv2 packets.
- GUI Security Hardening: Implements mandatory Content Security Policy (CSP) headers to mitigate cross-site scripting (XSS) risks in management interfaces.
2. Data Center Performance
- SSL Inspection Throughput: Achieves 68 Gbps on 3300E hardware – 25% faster than FortiOS 7.2.3 – through NP7 ASIC TLS 1.3 session offloading optimizations.
- VDOM Memory Allocation: Supports 80 concurrent virtual domains through 30% memory management improvements.
3. Protocol Modernization
- Quantum-Resistant Cryptography: Introduces experimental XMSS-SPHINCS+ hybrid algorithms for future-proof VPN tunnel encryption.
- HTTP/3 Standardization: Enables native QUIC protocol support for latency-sensitive applications like financial trading systems.
Compatibility and Requirements

Release Date
Officially published on May 9, 2025, this build replaces the deprecated 7.2.x branch.
Limitations and Restrictions
-
Legacy Hardware Incompatibility
- Not compatible with FortiGate 3100D/3200E models due to NP6 ASIC architecture limitations.
- SSL inspection requires CPUs supporting AVX-512 instruction sets.
-
Feature Constraints
- SD-WAN application steering limited to TCP-based traffic flows.
- Quantum-resistant algorithms cannot coexist with traditional IPsec configurations.
-
Upgrade Restrictions
- Direct upgrades from versions below 6.4.0 require intermediate builds (7.0.5 or later).
- Downgrading to 7.2.x after installation is permanently disabled.
