So some time yesterday my house was broken into

Came home to find the just about the whole house ransacked, nothing of much value taken and we have insurance so it's not the end of the world, but still a s**ty thing to come home to.
I'm also new to shooting and have recently installed by gun safe. During their ransacking the thief obviously came across the safe, and it looks like he's made some half baked attempt at getting into it. Just a few dings and scratches etc. They obviously didn't have a crowbar or any serious tools because there's no damage like that to the safe.
The cops said it was probably just a random burglary, hence why they didn't have any tools for the safe. Probably just kids with nothing more than a screwdriver to jimmy a door/window etc.
I'm actually so new to shooting that I don't have any rifles in their yet, so there wasn't any worries even if they did get in. Obviously a bit more worried about the future though now that some thief knows there is a gun safe in the house.
Looking to buff up the security a round the place now, to hopefully avoid a repeat in future.
So there, vent over at least

Any advice though would be awesome.
