Many security inspection devices have trouble scaling to handle the tidal wave of malicious traffic, much less decrypting, inspecting, and then re-encrypting it again. Using an ADC or dedicated SSL termination device to decrypt encrypted traffic ensures that your security devices can focus on the work they were built to do.
In addition, by using SSL termination, you can empower your web or app servers to manage many connections at one time, while simplifying complexity and eliminating performance degradation. SSL termination is particularly useful when used with clusters of SSL VPNs, because it greatly increases the number of connections a cluster can handle.
Offloading SSL or TLS traffic to an ADC or dedicated device enables you to boost the performance of your web applications while ensuring that encrypted traffic remains secure.
