The SA Series includes Juniper Networks Junos® Pulse, a dynamic, integrated, multiservice network interface for mobile and nonmobile devices. Junos Pulse enables optimized, accelerated, anytime, anywhere access to corporate networks, clouds, and the data they hold. Junos Pulse enables secure SSL access from a wide range of mobile and nonmobile devices, including smartphones, tablets, laptops, and desktop PCs, as well as Wi-Fi or 3G/4G and Long Term Evolution (LTE)-enabled devices. Junos Pulse delivers enterprises improved productivity and secure, ubiquitous access to corporate applications and data— anytime, anywhere.
