SSL acceleration refers to off-loading processor-intensive SSL encryption and decryption from a server to a device configured to accelerate the SSL encryption/decryption routine.
The F5 BIG-IP® product family uses specialized hardware built for SSL acceleration to remove processing bottlenecks and encrypt data without having to change application code. BIG-IP cuts costs and overhead by consolidating SSL certificates, eliminating the need to purchase SSL-capable software for each server within the network.
