Score: 78/100Rankings

The SentrySafe HD4100 is a portable fireproof and waterproof file safe designed to protect letter-sized documents and digital media from fire and flood damage. It features UL and ETL verified ratings for 30-minute fire protection and 72-hour water submersion, making it suitable for home or office use. However, the basic keyed lock is not burglary-proof, and the unit is heavy, making it less suitable for high-security needs or frequent relocation.

The SentrySafe X125 is a large digital security safe designed for home use, featuring solid-steel construction and a programmable digital keypad for pry-resistant security. It offers 1.2 cubic feet of interior capacity with a removable shelf for organization and includes bolt-down hardware to prevent theft. This model prioritizes physical security against forced entry but lacks fire or water resistance ratings.
