The overall concepts in this 2015 book are sound, if actually not paranoid enough for our times. Most of the details — particularly in what software to get — are necessarily dated.

There's occasionally the observation that nobody could have anticipated would be a groaner in 2025, like the characterization of Chrome and Firefox as the best browsers for privacy. The basic behaviors for keeping yourself out of harm's way (as much as possible) remain valid, as are the reminders of all the ways that "we are the product" for social media companies.
