SAST pricing

Hello, community,

I am researching about SAST.
In the paid offering it is written that SAST is a paid feature currently available only for the Gold paid plan.

Then I tried to configure SAST the way it’s described in the SAST documentation and it looks like it’s working:

So, I have 2 questions:

1) Is SAST truly a paid feature only for “Golden” members?

2) How can I configure SAST to block a merge request?
