"I just want to be sure that i can see information about Virus definition version, viruses detection... of non-domain computer"
No need to worry whether the client is part of Domain or Workgroup.
After creating a Client installation package, if you install it on the Domain Client or Workgroup Client it will start reporting to the SEPM and provide the information about the Defintion date, scan or not etc...
Only for laptop users who are roaming for them the information on the console will not be changed untill and unless they are on network.
Hope this address your query
