Encrypted Traffic Visibility
Encrypted traffic is referred to as the "the silent killer" because it often carries malware but never triggers alarms. Yes, encryption protects user privacy and sensitive business communications, but it also provides a hiding place for malware — because the traditional security tools companies have invested in are not capable of decrypting traffic in real-time.
This creates a security blind spot, and that's a growing problem for two key reasons. First, encrypted traffic creates a false sense of security because administrators never see or hear any security alerts. Second, the use of Secure Sockets Layer (SSL) and Transport Layer Security (TLS) encryption is on the rise. That means it's only going to be harder to get a handle on the magnitude of the risk of encrypted traffic traveling through an enterprise.
