Advice Request Block at First Sight in Group Policy for Windows Defender?

[Av Gurus]

I found this interesting option in GPE/Windows Defender:
"This feature ensures the device checks in real time with the Microsoft Active Protection Service (MAPS) before allowing certain content to be run or accessed. If this feature is disabled, the check will not occur, which will lower the protection state of the device.
Enabled – The Block at First Sight setting is turned on.
Disabled – The Block at First Sight setting is turned off."



Do you know about it?
Is this enabled or not by default (if not, did you enabled?

Here is something about that:
Enable the Block at First Sight feature to detect malware within seconds

"Block at First Sight is a feature of Windows Defender cloud protection that provides a way to detect and block new malware within seconds.

It is enabled by default when certain pre-requisite settings are also enabled. In most cases, these pre-requisite settings are also enabled by default, so the feature is running without any intervention."

i am glad to see that windows defender is improving however i would like to see a better performance while processing malware or while scanning, since it takes a lot of resources from the cpu or DD than the average AV

The internal components of Windows Defender is indeed interesting although not new, so the threat of defeating 3rd party program is never become impossible.
