Version 6.4.6 is quite old (released around early 2021). Fortinet recommends using the latest 7.x or 6.4.9+ for security patches. However, if you need 6.4.6 for legacy system compatibility, use the links below. Version 6
| Feature | 6.4.6 | 7.2.x+ | |--------|-------|--------| | ZTNA (Zero Trust) | ❌ | ✅ | | macOS Ventura support | ❌ | ✅ | | Always-up VPN | ❌ | ✅ | | Modern UI | Classic | Refreshed | | Security patches | ❌ EOL | ✅ Supported |
Verdict: Only use 6.4.6 if your FortiGate firewall is also on 6.4.x and cannot be upgraded. Otherwise, install 7.0.10 or 7.2.5 for better security and features.
