Hi @Eduards ,
Windows Server 2008 is out of support, you have to upgrade it ASAP to keep up-to-date.
There is an ESU program that you can subscribe to keep getting security updates.
For the SCEP updates, have you checked this similar post: https://learn.microsoft.com/en-us/answers/questions/81262/scep-for-windows-server-2008-standard-no-longer-up.html?page=2&pageSize=10&sort=oldest
