Interpeak's secure, certifiable, networking expertise will enhance Wind River's DSO strategy for delivering a standardized device software development approach that provides customers with the choice and flexibility to build any type of connected device."

Interpeak offers numerous products that securely connect next-generation devices to the Internet.
