I provide unattended periodical PCs, Servers maintenance service.
So, as one of requirements an email notification of started and ended a unattended session to admin and client (specific customer email) for each session timely as same as MSP360 backup notification email.
This request is very impoertant feature for manage authorized access in the end user side in order to ease to know when who is accessed our PCs timely..
And to know performed MSP tasks to them and as it becomes one of evidence for like compliance management.
Because typical customer never access MSP360 portral unless critical situations happen...

Tthe notification email needs to have the following info at least:

[Started session notification:]
Subject : Started unattended connect session to (PC name)
(Body)
Connect session Stated time: YYYY-MM-DD hh:mm:ss (Time zone)
Accessed User: Licensed User Name Or "Unknown" if unidentified accessed user
-- Unkonwn is mean unauthorized access.
-- Hance it is critical situation.
Access from : IP Address
Access Session ID: Session ID

[Ended session notification:]
Subject : Ended unattended connect session to (PC name)
(Body)
Connect session Ended time: YYYY-MM-DD hh:mm:ss (Time zone)
Total session duration time : HH:mm:ss
Accessed User: Licensed User Name Or "Unknown" if unidentified accessed user
-- Unkonwn is mean unauthorized access or having any issues in the session.
-- Hance it is critical situation.
Access from : IP Address
Access Session ID: Session ID

note: this features has ISL Online and Splashtop at least. So it is very helpful...
So I hope MSP360 Connect will become like them..
