Note:
1. IPsec VPN performance test uses AES256-SHA256.
2. IPS, Application Control, NGFW and Threat Protection are measured with Logging enabled.
3. SSL Inspection performance values use an average of HTTPS sessions of different cipher suites.
4. NGFW performance is measured with Firewall, IPS and Application Control enabled, Enterprise Mix traffic.
5. Threat Protection performance is measured with Firewall, IPS, Application Control, and Malware Protection enabled, Enterprise Mix traffic.
6. SSL VPN not supported on FortiOS 7.6.0 and above, for models with 2GB RAM.
7. SSL VPN only supported between 7.0.12 and 7.0.15
