How does my ISP see my outgoing network traffic? Do they see the actual music titles? Movie titles? and Podcast titles? Or is it just file type information that they see. I have about 15 users. 5 of them are in my house, 7 of them are scattered around the country and a few are in different corners of the world. I'm probably streaming about 10-15 hrs a day to various users mostly HD content. I don't have an SSL cert setup yet and wondering if I should if my ISP is snooping on my data.
