I always try to keep in mind protecting the reputation of geek squad overall is most important. In the end the “safest” decision is usually the best. I'd recommend YUMI on top of what others have recommended: because you can load a bunch of tools on to the same flash drive, and YUMI is just a bootloader for all of them.
It was highly encouraged at my precinct, so you don't have to use up time at work simply exploring the toolset.MRI itself is custom built Windows PE disc, with lots of business license programs loaded onto it, TDSS killer, Acronis, Webroot, etc.As others have said, there are a lot of free tools you can use. Unless something has changed in the last 2 years, you can 100% bring it home and use it for training purposes.
