What clearing firms do prop firms use?

What is the clearing firm for swifttrade? And how about others like Title Trading, WTS etc.?

Pretty sure Swift has a deal with Penson, not 100% sure.

At one time, Swift cleared through Penson. I see that they are no longer registered with FINRA. Anyone know if they went to the CBSX?
