The "E" in E-SBC stands for enterprise. A number of vendors and industry analysts have adopted the E-SBC acronym to differentiate session border controllers designed for the enterprise from those meant for service provider network deployment. While the role of session border controllers deployed in enterprise and service provider networks is functionally similar, both providing translation and security services, the two types of deployment vary widely in scale.

For example, while the an E-SBC may support anywhere from a dozen to several thousand SIP sessions, the session border controllers deployed by service providers are collectively tasked to support up to millions of unique sessions on a daily basis. And, they require different and larger amounts of hardware and higher levels of resiliency and management than an enterprise deployment.
