Do Kong Brain and Kong Immunity work together or are they separate services? Can I get one without the other?
They are two separate products that work together as part of an end-to-end solution. You don't need to get both, but obviously using both would yield the greatest benefits.
when will these be fully released?
We don't have a definitive timeline for making these generally available. We're going to make sure that anything we make GA has been fully battle tested.
