Checkr vs Lieberman RED IDM: What are the differences?

Checkr: Background check API. Checkr uses advanced artificial intelligence technology to better classify records without jeopardizing compliance; Lieberman RED IDM: An automated Privileged Identity & Access Management platform. It is a solution designed to establish a base of knowledge regarding the systems and devices in your network, what accounts are on those systems and devices, and enable the ongoing password or SSH key rotation for those accounts. Once the credentials are managed and/or securely stored in Lieberman RED Identity Management, they may be securely retrieved by users or processes in a variety of ways such as interactively through a web site or programmatically via REST or SOAP based web service.

Checkr and Lieberman RED IDM can be primarily classified as "Identity Verification as a Service" tools.
