One of the biggest challenges right now comes in keeping secure while we’re constantly connecting to systems of unknown trustworthiness. Even when I connect to this site, on a server that I built and administer myself, which I pay for entirely from my own pocket, there’s still that little doubt in my mind.
Most other sites provide much stronger reasons to doubt them, least of all because I have zero clue how good or bad they may be. There are companies that I trust more to maintain secure networks, and some I trust less. My experience as a pen tester has informed this a bit further, such that about a year ago I changed how I handle my browsing.
