It is essential that the safe you purchase has both a solid steel door and walls of substantial thickness. Without this base level of steel protection, any safe can be opened within minutes despite the hoopla of any advertised protection features. While the majority of top-selling safes on the market tout a plethora of protection features, virtually all fail miserably in this essential area.
The safe you choose must have at minimum a ½" thick solid steel door and a ¼" thick solid steel body.
Steel is very expensive and heavy, vastly increasing the safe's build cost and the cost of shipping overseas to the reseller. As a result, nearly all oversea manufactured safes (and even many local-built safes) cut these costs by making their safes with thin sheet metal wrapped around various forms of drywall to give the appearance of a robust safe.

Be highly suspicious if the safe manufacturer or reseller doesn't state solid steel, or lists "composite" for their wall or door material, as this can be anything from sheet metal wrapped around wood to sheet metal and drywall.
Also be on the lookout for safe sellers that list just "door thickness" rather than the barrier material type and thickness, as this is a recent trick many underhanded safe marketers employ. By listing the total thickness of the safe door including the safe dial, barrier material, airspace, inner bolt work, etc.... the provided figure can sound quite impressive, while actually preventing the buyer from obtaining any solid information on how thick the barrier material actually is or what it's made of.
