Question
What is the difference between standalone and integrated Sentry?
Answer
Standalone Sentry sits inline between the mobile device and enterprise resources such as the email server. It may be deployed as either a virtual or physical appliance. Integrated Sentry, which only supports Exchange 2007 and 2010, does not sit inline and is instead installed on the ActiveSync server. For most customers, standalone Sentry is the preferred option because it provides greater access control for both email and apps accessing corporate resources.
