AlertChimp manages users of cloud service like AWS and creates login session for limited time.
It allows to log and audit each login
It can add approval workflow for users - bob wants to use the cloud service as power user. He does not have that permission by default. He requests for an elevation of privilege for fixed time like 4 hours and the request goes to Alice and when she approves bobs account gets an elevation for 4 hours. He can login to with that role for 4 hours and then the privilege is revoked automatically.
It is possible to create Alerts based on request and logins. Alerts are delivered to phone or app.
