Welcome to the forum
If you're concerned about privacy, I wouldn't use a VPN provided by Cisco, they have been involved a fair bit with the NSA. You can get a paid one for fairly cheap, I use Private Internet Access and I like it, no major speed decrease (maybe 50mb/s on a connection normally ~57mb/s), and encryption can go from nothing all the way up to AES-256, SHA256, and RSA-4096. It's about $40 USD a year, and you can pay with quite a few options, including Bitcoin if you want to stay even more anonymous.
