Hi, First off, I apologize if this question has been answered before (I have read many of the entries in this forum, but I'm still a bit confused) or seems very basic (I'm not a computer expert by any means). I am very concerned about computer privacy for a number of reasons. Mainly, because my job entails that I work with sensitive information. I also travel a lot and rely on public wi-fi hotspots for internet access (I know, they're very insecure). So, I've been thinking about using a commercial VPN. My questions: 1. If I use VPN is it really secure insofar as I could confidently send sensetive files via email or use my credit card online? 2. There are so many of these commercial sites and they seem to offer different technologies (secure tunneling, etc). I'm only familiar with CISCO VPN which I used at my previously employer - do these commercial sites use a VPN similar to that? (I ask, because CISCO seems very easy to use). Also, at home, I'm wondering about all this talk I hear about ISP's logging my internet use, or worse, accessing the actual data I'm sending to others. Does a VPN prevent that? Does Tor? If either of these do, why on earth would anyone use anything else? Thanks in advance for any info!
