Liberty safes are “high security safe” according to Liberty Safe. This company was founded by an engineer and their handiwork till this day reflects his influence. Their safes are secured, which is why we included ProVault 12-Gun Safe in this list. In fact, a few of their safes have biometric scanners that make it impossible for perpetrators to break-in. Hence, you can keep your valuable, unattended jewelry, gold, cash, and documents in these safes too. Yes, their portable pistol safe is that safe!
