I am still using FreeOTFE, which is very similar to TrueCrypt, right down to being abandoned several years ago. But it still works and is relatively seamless. Mount your encrypted file or drive, do your business, dismount and move on. I am not a hacker or a security nerd, but I travel with a lot of data, including scans of medical documents and important papers that I wouldn't want randomly exposed to the world if I left my laptop behind in a plane or hotel. I also use Express VPN on the road since I spend a lot of time on sketchy hotel wireless connections. Seems secure, relatively painless to set up for a regular guy user.
