...after you did the research for the company, you both agreed that the OS encryption utility is NOT enough, right? the independent encryption softwares are crucial... right?
It's surprising how many consumers aren't at all conscious of the nature of encrypting data in the first place.

For those even aware, the consumer thinks the OS encryption feature is sufficient, as long as their password is safe.

If the consumer can be sufficiently educated on this point, or if you find a consumer that is, then yes, they'll easily realize the encryption feature within the OS is nearly useless.

Not just from the standpoint that it is not secure, but if the OS itself gets trashed, they may never be able to recover the encrypted data stored by the OS.
