Encryption is one of those things you might just need and don't know it. Wikileaks used 7zip to protect their files and even the government won't be cracking them for a very
very long time.
So you can keep your your office documents, pictures, videos, and whatever else on a USB removeable drive and not have to have a panic attack if it gets lost. Because it will take the best of the best
with the most powerfull computers in the world to crack it. And it would take a few thousands years. And that is piece of mind no matter what you have stored there.
The way we encrypt files at AHD is with Veracrypt. It's versatile and will work on every OS and it's not proprietary like Microsoft's encryption.
