How is EmPass licensed?

Overview of EmPass functionality:
Each EmPass Agent listens for password changes as they occur. When an Agent detects the password change, it is sent to the Central server for processing. (Then delivered to a DC on the target domain)

EmPass is licensed by
a) the number of EmPass Central Servers (usually one) and
b) the number of EmPass Agents (installed on every source DC).

So, the minimum initial purchase would be:
1 Central Server license
1 EmPass Agent license

Note, this minimum covers only a single DC. Realistically, the number of EmPass Agents licenses should match the expected number of DCs in the source domain (Note: additional Agent licenses may be purchased later).

When requesting a quote for EmPass, specify:
How many Central Servers
How many EmPass Agents
