An increasing amount of malware and potentially unwanted apps exploit the fact that organizations are simply not using SSL inspection. Network administrators' main fears are that SSL inspection will have a performance impact or cause something to break, impacting the user experience.Sophos Firewall removes the blind spots caused by encrypted traffic by allowing you to use SSL inspection while maintaining performance efficiency.We believe you should never have to decide between security and performance. Sophos Firewall includes a highspeed deep packet inspection (DPI) engine to scan your traffic for threats without a proxy slowing down the process. The firewall stack can completely offload the processing to the DPI engine, significantly reducing latency and so improving overall efficiency.
