Juan is looking to use Tor for encrypted security. Leo says that Tor was invented by the US Navy and it works by making your traffic obscure. Tor is used for anonymity, and it's a bit difficult to set up, but using a Tor browser makes it a lot easier. If Juan is concerned about privacy online, Tor is a good option to look into.
There are some security issues to keep in mind, however. The FBI paid universities to break Tor so they could peak inside it, and all access was in the clear for six months. So it's not a perfect system. It's also a bit slower since it routes traffic through various ISPs around the world to keep you anonymous. It'll keep you protected against every day use though.
