EncFS is described as 'Provides an encrypted filesystem in user-space. It runs without any special permissions and uses the FUSE library and Linux kernel module to provide the filesystem interface. You can find links to source and binary releases below' and is an app in the backup & sync category. There are more than 50 alternatives to EncFS for a variety of platforms, including Windows, Mac, Linux, Android and iPhone apps. The best EncFS alternative is VeraCrypt, which is both free and Open Source. Other great apps like EncFS are Cryptomator, TrueCrypt, LUKS and DroidFS.
