I work with data security in both law enforcement and the private side. BetterCallSaul is right, workplaces can see what you are doing on their internal networks if they really want to. Even with SSL enabled. That's the bad news. The good news is, the I.T. staff do not have time to look at all that all the time. So you would need to be targeted by a manager who asks the I.T. staff to look at your traffic in order for them to know what sites you go to and what you post/read.
Now on the law enforcement side of the line, we can do a lot too. Powers vary based on if you are engaged in criminal activities or just a civil case (like a woman divorcing you). In law enforcement our God powers are only on those doing child porn or terrorist related activities.
PM me if you want to ask some specific questions. But bottom line, I don't see where SSL on Sosuave would really help anything.. But I could always be wrong..
