In Service Optimization configuration, sensitive settings are often stored in clear text, which means that they are clearly readable to anyone with suitable access. Xoom addresses this problem by transparently encrypting sensitive settings, making that information irretrievable from XoomXML files while, at the same time, preserving all use cases.

These features were introduced in Xoom 3.7, replacing the previous method of removing sensitive information with the Remove Sensitive Information report. This had the unfortunate side-effect of making it necessary to re-enter sensitive information on the target system after deploying XoomXML files that have been cleaned in this way.
