Do i need a CloudRail Subscription if i use my own azure account

Yes, CloudRail always requires a CloudRail subscription. This is due to the fact that CloudRail is a managed service. The subscription includes things like the Device Management Cloud, support, remote security and feature updates and much more. There is a free developer plan for testing available.
