FWIW, I know people who know the creators of Carbon Black, and I am familiar with the skill level and mindset that they come from.

If the founders are still involved with the company, I expect the security to be top notch and the privacy to be at least respectable or better (depending on how much business forces forced them to collect some telemetry to better market their product).

I haven't used it personally, but I'd say they should be on your list of things to look into.
