It's a bit of a weird game in that most games start you out with few options/skills and little difficulty. In The Swindle, where everything is fatal, it means you have to get up close to defuse mines, leap spikes without multiple jumps and kill enemies personally, and that means that each slip is deadly.
Later on you can detonate mines and generators from a distance, use EMP to knock out robots from the other side of a wall/door, hack computers so quickly that the patrolling bots and camera arcs aren't a problem, blow up spikes and cameras, turn bots against each other and generally deal with most of the threats before you go in, and even then you can do so under a cloud of steam to stop being spotted, or with an auto-steam purge to stop being spotted once automatically. If you get something wrong, it usually isn't fatal, it just means you need to try something else (or wait for your abilities to recharge).
