We evaluated BitLocker and Symantec PGP.

We are currently doing a POC with Bitlocker. I want to decommission the Sophos Safeguard and enable BitLocker for my bank. I'm working on that right now.

We did not evaluate other options before switching from Kaspersky to Sophos.

We evaluated other encryption solutions and we found that this was the easiest one to use, especially with cloud management.

Another reason that we chose this solution is that it is a standalone package. Kaspersky have an encryption solution, but it is part of a bundle with their endpoint solution. The advantage to standalone is that you can use it even if you don't have any Sophos endpoints. 

We evaluated CrowdStrike, prior to going with Sophos SafeGuard.
