What is the free antivirus for the organization?

Question

Windows

Must be able to in .msi, and also managed via GPO. Is this generally possible? Read about WSUS, is it real?

Answer 1

Windows defender and hard policies.

Answer 2

For third party programs via WSUS - https://sourceforge.net/projects/localupdatepubl/

Answer 3

Wsus is real - BUT it's not an antivirus, but an update server to centrally roll out updates to groups of computers in your domain.

Answer 4

Free, as mentioned above - windows defender. You can steer it just by means of GPO https://docs.microsoft.com/en-us/windows/threat-pr... as an example, you can cut down its UI so that the user does not even try to interact with it.
It's also worth looking in the direction of App Locker, let's say it's allowed to run only on certain paths, so that users can't put themselves any software in their profile. Well, wsus can be useful to you if the fleet of machines is large, there is a desire to make test groups, etc.
Separately, it doesn't make sense.
