I always prefer a functional test.... Download steam then a f2p game. Check your download rate. Delete the game then retry it on a cable connection.

to be honest, if you are truely concerned about the security of everyone's SSNs and personal information, you can always turn to an archaic form of secure correspondance: certified mail. every person who handles certified mail must sign for it in ink, and it is a Federal Felony to lose/misplace/steal certified mail. Dont quote me on this, but I think the US military has approved certified mail as one medium of transporting items labeled "SECRET". Given this method will take more time, but the end result will be probably the best solution to security of the data in transit. if you hate the consultant, print off the data and mail it to him, and if ya wanna be nice, just toss a CD in mail.
