Compatibility and Requirements
| Category | Specifications |
|---|---|
| Supported Hardware | FortiGate 500E/500EF/500ET |
| Minimum Memory | 32 GB DDR4 (64 GB recommended for IPS/IDS) |
| Storage | 128 GB SSD (≥32 GB free post-upgrade) |
| Dependencies | FortiOS 6.4.10+, FortiAnalyzer 7.2.5+ |
| Unsupported Features | TLS 1.0/1.1 (disabled by default) |
Critical Note: Downgrading to builds below 6.4.11 will irreversibly erase quantum-safe encryption configurations.
