    Our DSL is not more working, Centurylink not wants to invest in optic fiber, they still use that century old copper wire. We plan to get Viasat, a satellite internet. I heard that because of latency, VPN may not work. I use TunnelBear VPN for my critical data on DSL and would like to use it also for Viasat. Has anyone experience with that to tell if it works? Thanks for any info.

    You are correct about latency being an issue with satellite communications. To compound problems, the latency of your satellite connection may not be consistent.

    I deployed a system utilizing a business class satellite connection. Even with this service, the latency was 500ms. From what I recall, we explored the use of a WAN accelerator but this would complicate matters with the site to site VPN that was part of this system. In the end, the 500ms was good enough to support an AES 256 encrypted tunnel.

    In regards to your statement about using a proxy service to "protect" your critical data, you're wasting your money. These proxy services DO NOT add any additional security when you use your own Internet service. So if you think you'll get better performance with a satellite service over Century Link, I wouldn't let not being able to use a proxy service stop you from changing services.
