Honestly those cables give a false sense of security. They are trivial to cut. I see them more useful in automobiles where there are fewer solid mounting options and most auto burglars won’t take as much time or come as prepared as a home burglar might (unless they are pros or maybe they’re already inside an enclosed garage where the risk of being seen is lower).
The Wyze safe, as most “real” home safes, comes with bolts to secure it to a floor/wall/furniture or other sturdy fixture, which is quite a bit more difficult to overcome than a cable. Not impossible, but takes more time, tools, noise and/or destruction to remove because you can’t easily get to the attachment points without getting into the safe itself. So lack of a cable doesn’t concern me here. I’m more interested in seeing the results of a direct attack on the mounted safe itself.
