To answer the original question, we have been using KL FDE for about 4.5 years. We have 250 machines of which 120 are laptops with FDE. We use the full AV, patch management and encryption features. When it works it's good. However, we are longing for our migration to W10 when we will be able to use Bitlocker instead of KL FDE. There are too many overheads with FDE: Every time we upgrade to the latest version we have to pull all the machines back in, decrypt them, remove the old version, install the new version and recrypt. We have lots of problems with Dell laptops. I currently have calls open regarding inability to add accounts, inability to remove duplicate accounts, machines encrypting when they shouldn't and FDE apparently stopping network adapters from working (reassuring to be told that FDE should not affect network - I couldn't agree more). The support guys are generally great but the overhead is just too large. I expect a product to just work, not to have to spend hours on each new machine running tests in order to determine which private fix I need to install. If a fix is needed then it should be included in an automatic update and installed by the product as required; it should not be necessary to find it and tailor each installation. We are currently running 10.3.0.6294. I hope that helps.
