Automatically update newly released built-in policies

Hi gh91, 

if you are referring to the builtin policy initiative, Azure Security Center is using, then the answer is yes. The builtin (default) ASC policy initiative will automatically be updated with additional policies once they are published. If you are using a custom policy initiative, there are two different scenarios:

1. if you are using builtin security policies in your custom initiative, these policies will also automatically be updated once there is a change. However, we will not update your policy initiative by adding additional policies once they are released.
2. if you are exclusively using custom policies in your custom initiative, these policies will not automatically be updated.

Best regards,
