What software is there to bypass work filters?

I have been told there is software out there that can be stored on your USB pen drive that lets you bypass work internet blocks.



I've searched on Google for the last hour and a bit and had no such luck in finding it.



I don't suppose you have any idea where I can find it?What software is there to bypass work filters?
While there is software to bypass your security I should tell you that it will still show up on your administrators log. This can result in your dismissal and under certain circumstances your employer can charge you and take you to court. It is illegal and who would employ you with a criminal record. Give the idea up.
