Secure Sockets Layer (SSL) or Transport Layer Security (TLS) is an application-level protocol that provides encryption technology for the Internet.
From virtually nothing just a few years ago, it is not uncommon to see 50 to 70 percent of data centre traffic encrypted today. While encryption improves security, it also creates new problems: Malicious traffic could be encrypted, and DPI detection mechanisms would be rendered ineffective because they would not be able to look inside this traffic. Another problem is the additional processing power required by the Web server to achieve this encryption/decryption.
SSL offload relieves a Web server of the processing burden of encrypting and/or decrypting traffic sent via SSL/TLS. The processing is offloaded to a separate device (physical or virtual appliance, or server software) designed specifically to perform SSL acceleration or SSL termination.
Pulse Secure vADC is a software-based application delivery controller (ADC) designed to deliver faster and more reliable access to public websites and private applications. Pulse Secure vADC provides the functionality for SSL/TLS Offload, enabling organisations to scale application servers by up to 3x by offloading TCP and SSL connection overhead.
