Bitglass is able to integrate with AWS Transit Gateway Connect to connect with existing SD-WAN solutions. Traffic destined for the web, the cloud, and even on-premises resources can be routed to Bitglass for real-time security enforcement. This stands in stark contrast to competing SASE offerings which integrate with a limited set of SD-wAN solutions. These alternatives then require security teams to build and maintain complex, resource-intensive solutions, such as the use of the technology from Bitglass.
