There are no tanks or firetrucks or massive surveillance initiatives among the items we’ve dubbed the best security innovations of 2018. That’s because safety happens by the inch, through a relentless effort to stop the simple vulnerabilities that can lead to major threats—on our doorsteps, overseas, and in our streets. Our honorees down malicious drones without risking collateral damage, help military vehicles transverse tough terrain, offer new ways for police to capture fleeing assailants, and prevent porch pirates from nabbing our packages. Even our old friend the combination lock got a snoop-stopping upgrade. All the better to protect us with, my dears.
