You should be aware that TrueCrypt development was no longer maintained/updated since 2014.
Several security bugs have been not resolved.
You fan review this article about some alternatives that I summarize them in this article too.
Here they are Truecrypt alternatives (from my side I use, normally, 2. and 7. options):
- VeraCrypt You can find a full list of improvements and corrections that VeraCrypt made on TrueCrypt here. It is open source and free.
- Bitlocker no encrypted containers ability and not open source.
- DiskCryptor supports encryption of external devices including hard drives, USB drives, CDs, and DVDs
- CipherShed
- FileVault 2 Apple’s answer to Bitlocker, no encrypted containers ability and not open source.
- LUKS
- SafeHouse Explorer – 3.01 Portable
