It must be Bertram. He controls the law enforcement network but nobody knows he is RJ since he pretends to be part of RJs network. He is hiding in plain sight.
He works with Stiles who controls the Visualize network. Stiles knows Bertram is RJ and Bertram lets Stiles do what he wants with Visualize :)
Bertram is happy to let Jane think Stiles may be RJ. Stiles controls Haffner and Haffner keeps an eye on Stiles.
