A concern that I have with Preseam (or any other vendor like this) is that it requires me to put a single box (usually a Dell server) right in-line with all of my customer traffic. All of a sudden, my entire customer network is reliant on a single Dell server. I know that Procera and maybe some other vendors offered bypass modules for this type of thing, but what are Preseam customers doing? Is this not a concern for you?
