Imagine the damage a hacker can do after discovering a server’s private encryption key with over 90% of your network unit system.

From URL filtering to malware detection to IPS signatures, all advanced network security appliances rely on deep packet inspection (DPI) and full application message reassembly to detect and block prohibited or malicious content.
As TLS encryption becomes the default mode of network communication between clients and servers, this is something that quietly happens to the next-generation firewall (NGFW) and intrusion prevention system (IPS) operators without ever experiencing any changes at the device configuration or policy levels. The only way to regain full network-level visibility into the traffic flows and deliver a reasonable threat protection efficacy is to enable TLS decryption prior to or at the security device level.
