That comment is really not reassuring. I'm happy that you take privacy and security very seriously, that's great to hear. However industry best practices is a little vague and 'to ensure that your computer is not compromised in any way' makes it sound like you want to do the job even the best antiviruses have trouble doing.

Furthermore I'd argue that if someone steals your machine from your house/car/etc, getting the keys to any remote machine should be trivial just by looking at the stored passwords and configuration.

But maybe I misunderstood what you were saying, sorry if that's the case.
