Law firms using independent (aka contract) paralegals will see nothing new.

The same old vetting of know who you are contracting with:  paralegal resume and references from prior customers, background check (may now include VOLUNTARY business or personal credit report - identity theft fear), "office" clean desk, locked cabinet (no prying guest or family eyes), secure internet connection, etc. 

The only real difference I hear is that instead of actually "doing it, business as usual since day #1," business customers in the lending industry want to read "printed on paper" that you keep your work confidential.
