MDI and multi-tenancy
Hi,
We have the following setup:
- Developer Azure Tenant and developer on-prem domain (sync'ed via AADConnect)
- Production Azure Tenant and Production on-prem domain (sync'ed via AADConnect)
We would now like to start using MS Defender for Identity.
Can we install the MDI sensor on all domain controllers (in both Developer and Production on-prem domains) so that they all report to the same MDI Portal running in the Production Azure Tenant?
Thank you,
SK

Should work fine i believe. As long as you have the licenses in your production tenant to cover both forests. You can read more here

Hi skjivert,
Thank you for the link - even though it mentions "Forests", you reckon it should therefore also apply to "Tenants"?
Secondly, if a company has E5 licensing, they will have MDI - correct?
Is there also a limit within this E5/MDI license on the amount of domain controllers for the sensor deployment? Or are there any additional costs (other than E5)?I thought E5 included MDI.
Thx

Hi ShimKwan,
Yes, E5 licenses come with MDI.
MDI automatically onboards all users in the tenant (Reference below) and limit for DC Sensor should be 350.
