I have a safe from ConsoleVault, that fits perfectly in my Toyota Tacoma center console. It was easy to install and is bolted in, so hard for someone to remove. I got the 4 combo dial lock, but they make different models that fit a wide range of vehicles. I didn't lose all that much space from the original console size in the truck either, and I'm happy with the purchase.
For anyone interested, I post their link below.
