Home Resource Center Glossary SSL Offloading

Secure Socket Layer (SSL) is a commonly-used protocol that helps to ensure the security of HTTP traffic traveling across the Internet. SSL relies on public- and private-key encryption to encrypt communications between the client and server so that messages are sent safely across the network. By encrypting the transmission, sensitive information, such as a user's login ID for an online banking session, or perhaps a credit card number, is protected and kept out of the hands of potential hackers and criminal organizations.

You can ascertain whether or not a site is using SSL because the URL will say "https:" as opposed to just "http:" - the extra "s" indicates that SSL is being used to encrypt the data.

One of the drawbacks of SSL is that it requires more processing power. By using the A10 Networks AX Series of Application Delivery Controllers, organizations can take advantage of specialized acceleration ASIC technology, which is dedicated to processing SSL requests.

To ensure that the load balancer delivers optimal performance, the A10 Thunder Series appliances have integrated ASIC chipsets for dedicated encryption/decryption capabilities, featuring the industry-leading Cavium NITROX® Security Processor chipsets. This ensures the AX Series Advanced Core Operating System (ACOS) and multi-core CPUs are free from bulk SSL transactions, and ready for other load balancing instructions.
