Sangfor NGAF offers comprehensive security features for connection, server, and threat protection with detailed DPI capabilities for enhanced control. Technical support is responsive and efficient. While cost-effective with features like WAN optimization, the product recently saw price increases. The firewall system requires ongoing improvements due to rising threats. Sangfor lags in market exposure, dominated by Fortinet, and lacks attack mitigation recommendations despite robust comparative features.
