The Nuage Networks 7850 NSG-E has a small footprint, and can be shipped and installed at an enterprise branch location without requiring any network engineering expertise. Since the 7850 NSG-E is centrally managed, it improves the efficiency and productivity of branch operations while eliminating the need for any on-site IT support. The 7850 NSG-E is on-boarded via a secure bootstrapping process that uses zero, one or two-factor authentication depending on the branch and installer trust-model and security posture. Once bootstrapped, it enables instant networking capabilities at the branch.
