Voltage SecureMail Mobile Edition Now Supports “Split Domain” Network Architectures

For enterprises that have split domain network configurations, Voltage SecureMail Mobile Edition now allows internal users who are coming from public mobile networks to reach internal Voltage Key Servers. For security reasons, some organizations use a split domain configuration to segregate networks and users.

A split domain network configuration determines which network (including tenants, districts, settings, etc.) can be accessed by which users and/or groups. Most commonly a split domain configuration is used to separate internal and external networks and users. Voltage SecureMail Mobile Edition now supports these configurations. The new capability allows internal mobile users to have access to the internal network to authenticate and download keys to access secure messages when they are using a public mobile network.
