  • Encrypts data in Hard Drives to improve security
  • Easy to manage
  • Allows you to encrypt removable media as well
  • Encryption is not resumed after being suspended sometimes
  • Sometimes it take a long time to encrypt a disk
  • Encrypting secondary drives can be tricky

  • It is fairly easy to use, from both a technician and users point of view. The install itself is pretty simple, and setup of the software is also fairly simple. For users, it is easy to use the software to encrypt the computer.
  • It doesn't seem to use a whole lot of system resources when the encryption is enabled on the computer. You shouldn't experience any slowness of the computer, other than the time it takes to first encrypt the computer.
  • It serves its main purpose very well, and that is to protect computers from intrusions/data breaches. It is particularly good for protecting computers that are accessing/storing sensitive/confidential data.
  • Users need to make sure their computer can support encryption. There is a special TPM chip that is needed to be able to encrypt the computer, but most newer computers today should have this built-in.
  • There is some slowness of the computer with the encrypting/decrypting part of the software. This part can also take a long time to complete, depending on the size of the hard disk.
  • It is very important that the recovery key is never lost, or else the user may never be able to unlock their drive. Microsoft should look into maybe having a feature which would automatically upload the recovery key to the cloud (in a secure manner).

  • Encrypt the hard drive seamlessly
  • Protect data to be extracted from the hard drive once out of the computer
  • Bitlocker should be paired with a proper backup solution, if no backup, data is gone for ever when the drive has an issue.
  • Bitlocker mainly works if the encrypted drive is pulled out of the computer, it is useless when paired with the computer. I mean if someone stills the computer, the hard drive will be inside so the the real life scenario of someone stealing the drive but not the computer is very unlikely to happen.

  • On my customer's machines, it's convenient that BitLocker can be set up to automatically open an encrypted volume so that my customer doesn't have to enter the passphrase every time they log in.
  • BitLocker is compatible with NTFS and ReFS which gives you options for your storage.
  • There doesn't really appear to be any performance penalty for encrypted volumes, so it is a seamless experience.
  • When encrypting external devices such as USB flash drives or USB/eSATA hard drives, it would be handy if there was a cross-platform (MacOS, Linux) utility to at least be able to read the encrypted data after entering the passphrase.
  • A variety of crypto ciphers would be a good option for BitLocker to offer.
  • A self-destruct option would be helpful if an attacker were to try to brute-force passphrases to attempt to gain access to the encrypted volume.

  • Encrypts the entire drive and provides a high level of security.
  • In an Active Directory environment, you can set up BitLocker to automatically save keys to AD.
  • As part of Windows, no additional licensing costs.
  • Set up and configuration is relatively easy.
  • Uses TPM module to increase security.
  • There is a read/write impact on performance, but the protection is well worth the minor performance hit.

  • Practically no impact on read performance and low impact on write performance compared to others.
  • Integrated into Windows/no additional cost
  • Easy deployment
  • Whole drive encryption
  • Uses hardware chip to offer better security
  • Even if it's the best we tested, I think write performance could be improved. Maybe with dedicated hardware inside the TPM?
  • No integration with OS password is a shame as most others have it and it is Microsoft on Microsoft so they can probably do it better then anyone else and safer.
  • I wish they would support multiple passwords like FileVault on macOS. If it's a shared computer, you have to give the only password to Bitlocker to both users.

  • Part of Windows Pro and + licensing.
  • Very easy to deploy and maintain.
  • Embedded in the software, and Windows patching.
  • Well known
  • Cannot Dualboot (disaster)
  • Should be integrated in AD out of the box (MBAM)
  • Add 2FA (with RSA/Authenticator?) out-of the box

  • Definitely encrypts the drive and provides a high level of security
  • Protects the drive from any tampering and good luck trying to get back the data after lots of bad attempts.
  • Performance hit with non SSD hard drives or up to date equipment
  • Slow boot times due to the encryption of the drive.
