I just returned from a two-week trip to New Zealand and then to Singapore. I wanted to have secure communications via email and via Google Duo (similar to Apple FaceTime but for both iPhone and Android cell phones) and I also wanted to be able to surf the web securely. I didn’t want any hackers to view online transactions with my bank account, credit card companies, or any online purchases I might make while traveling. While most online transactions use SSL (Secure Sockets layer) encryption, SSL has been hacked.
NOTE: See my earlier article at http://goo.gl/nbkl1g for just one example of SSL being compromised. There are other methods of cracking SSL encryption as well.
If I was using only one laptop or cell phone, I probably would install VPN software in that device. That probably would be the simplest and cheapest solution. However, I wanted to secure my Macintosh laptop, the Chromebook laptop, the Android cell phone, and the VoIP telephone I carry with me when traveling. (Someday I will write about why I carry a VoIP telephone. For now, I will simply state that I perform live telephone support for one of my business ventures.) I wanted one device to secure all of these systems.
