## OS Full Disk Encryption
Modern operating systems include [FDE](https://en.wikipedia.org/wiki/Disk_encryption) and will have a [secure cryptoprocessor](https://en.wikipedia.org/wiki/Secure_cryptoprocessor).
For encrypting the drive your operating system boots from, we generally recommend enabling the encryption software that comes with your operating system rather than using a third-party tool. This is because your operating system's native encryption tools often make use of OS and hardware-specific features like the [secure cryptoprocessor](https://en.wikipedia.org/wiki/Secure_cryptoprocessor) in your device to protect your computer against more advanced physical attacks. For secondary drives and external drives which you *don't* boot from, we still recommend using open-source tools like [VeraCrypt](#veracrypt-disk) over the tools below, because they offer additional flexibility and let you avoid vendor lock-in.
