Till you get to actual safe doors taken from old banks that you concrete into a structural safe they're all more a suggestion to keep out than anything else. It's why the really valuable things in my home aren't in a safe, they're in an ordinary container in a closet I can grab and run with quick in an emergency. Let any idiot robbers try to steal my office safe and carry it off, has nothing but old paperwork in it. The gun safe on the other hand, best security is just to electrify the outer case with house current. Anybody who doesn't know to turn off the hidden switch first is gonna smell the bacon.
kind of my point; it's not going to stop a professional, dedicated criminal, even the concrete/bank safe door isn't, if it's a criminal who thinks he can get a reward equal to the effort. (also, that shit is Ehx-PENNN-sive.)
Generally speaking, the 'suggestion' to stay out is a good suggestion for a number of opportunistic reasons, including homes with young people in them, or where young people are likely to visit, as well as because sometimes with an insurer (and you SHOULD be insuring at least some of your guns, if they're valuable-ish or your holding them to resell as investments) you can get either a discount on your premiums, or you can get coverage in your state for having a secure lockup.
A locking cabinet (let's face it, most affordable 'gun safes' are just locking cabinets) also provides for a nice way to keep them stored and keep them nice when you're not knocking about with them in the outside. (this is because you can do things to improve climate control, like using those bags of silica to reduce humidity inside the safe...)
Depending on how much you want to spend, you can get some decent (but not in any way foolproof, sorry...) security using relatively cheap, simple, locking cabinet type "Gun Safes" if they're secured properly and you bother to maintain them. (*everything like this has some maintenance involved, even if it's just adding a drop of 3 in 1 oil to the lock and hinges.)
whatever it is you end up buying, it's advisable to RTFM. (Read the Frikking Manual) and note the 'advised' portions as 'you really ought to do this'.
The biggest security move you can make, is knowing you need to make a security move, then making it. It doesn't matter if it's electronic, combination, or Key based, as long as you DO IT.
