More Details on Our Top Picks
SentrySafe Fireproof and Waterproof Large Safe with Digital Keypad, Override Key, and Adjustable Shelf, 0.81 Cubic Feet
This SentrySafe offers a balanced combination of fireproof and waterproof protection along with user-friendly features like a digital keypad and override key. Compared with the larger SentrySafe Waterproof Floor Safe, it provides more flexible access options in a compact form, though it sacrifices some internal capacity. Its UL and ETL certifications guarantee fire resistance for 1 hour at 1700°F and water resistance for 24 hours, making it ideal for sensitive documents and valuables. The adjustable shelf enhances organization, but its reliance on batteries could pose a risk if not maintained. Heavy enough to require assistance for moving, it’s better suited for secure, permanent placement rather than frequent relocation.
Pros:- Combines fireproof and waterproof protection in one unit
- Includes override key for emergency access
- Secure bolt-down capability enhances theft deterrence
Cons:- Limited internal organization options
- Requires batteries which need periodic replacement
- Heavy weight makes relocation difficult
Best for: CPA offices needing a reliable, all-in-one safe with easy access for daily use and occasional emergencies
Not ideal for: Small offices or spaces where frequent relocation or minimal size is a priority, due to its weight and bulk
- Capacity:0.81 Cubic Feet
- Fire Protection:UL Classified for 1 hour at 1700°F
- Water Resistance:ETL Verified for 5 inches of water for 24 hours
- Color:Black
- Batteries:Included, with 5+ year lifespan
- Locking Mechanism:Digital keypad with override key
Our verdict“This safe suits offices that prioritize versatile, reliable protection with straightforward access but are prepared for its size and weight.”
Hollon HS 880E 2-Hour Fireproof Office Safe
The Hollon HS 880E stands out for offering a solid 2-hour fire resistance and impact rating, making it a top choice over the SentrySafe Waterproof Floor Safe for durability during catastrophic events. Its 3-way locking chrome bolt door ensures security, while the interior adjustable shelf allows flexible organization. The safe’s impact rating of 30 feet adds peace of mind for accidents involving falls or impacts. However, it lacks digital or biometric access, relying on mechanical locks, which may be less convenient for quick retrieval. Its internal capacity isn’t specified in detail, but the overall design favors high-impact, fire-resilient storage over high-tech features.
Pros:- Provides a full 2-hour fire protection
- Impact rated for 30 feet, suitable for accidents
- Includes adjustable interior shelf and locking drawer
Cons:- No digital or biometric lock options
- Limited details on interior capacity
- Bulkier design may require dedicated space
Best for: CPA firms needing a robust safe with long fire protection and impact resistance for critical documents and assets
Not ideal for: Offices seeking quick electronic access or modern biometric features, due to its mechanical lock system
- Fire Resistance:2 hours
- Impact Rating:30 feet
- Locking Mechanism:3-way locking chrome bolt
- Interior Features:Adjustable shelf and drawer
- Door Détente Device:Yes
- Anchor:Included for bolting to floor
Our verdict“Ideal for offices prioritizing durability and impact resistance over high-tech convenience.”
SentrySafe Black Fireproof Waterproof Floor Safe with Dial Combination Lock, 2.05 Cubic Feet
This SentrySafe floor safe offers a generous 2.05 cubic feet of capacity, making it suitable for storing multiple sensitive items, documents, or digital media. Its dial combination lock adds a traditional security layer, and the fireproof and waterproof certifications match smaller models like the SentrySafe FPW082HSB. The large exterior dimensions and weight make it less suitable for frequent access or relocation but excellent for long-term, secure storage. Compared to the digital options, the dial lock may be less convenient but offers a straightforward, low-maintenance security method. Its heavy steel construction and pry-resistant features provide peace of mind against theft and forced entry.
Pros:- Large capacity for multiple valuables
- Provides fire and water protection
- Durable, pry-resistant steel construction
Cons:- Heavy and difficult to move
- Lacks electronic or biometric access
- Requires installation for security and stability
Best for: Offices needing high-capacity, long-term storage with straightforward security for documents and media
Not ideal for: Places requiring quick, electronic access or frequent retrieval, due to its bulky size and dial lock
- Fire Resistance:1 hour at 1700°F
- Waterproof Duration:24 hours in water up to 8 inches deep
- Exterior Dimensions:18.6 W x 19.3 D x 23.8 H inches
- Interior Dimensions:14.8 W x 11.9 D x 19.6 H inches
- Capacity:2.05 cubic feet
Our verdict“Best suited for offices with ample space seeking durable, high-capacity storage with simple, reliable security.”
10 Cuft Fireproof Waterproof Safe Box for Home | 1700°F 35-Min Protection
This sizable 10 cu ft safe excels in offering high fire resistance—up to 1700°F for 35 minutes—and fast biometric access for multiple users, making it ideal for offices with many staff or multiple keyholders. Its steel shell and fireproof insulation provide tough protection, while the biometric system offers quick, contactless entry, unlike the slower keypad or dial locks. However, its lack of wall or floor anchoring could be a concern in high-theft areas. Its significant weight and size may limit placement options, but for safety-critical environments, its combination of fire resistance and biometric convenience makes it a compelling choice.
Pros:- High fire resistance up to 1700°F for 35 minutes
- Fast biometric fingerprint access for multiple users
- Heavy-duty construction deters forced entry
Cons:- No wall or floor mounting options
- No waterproof features beyond fireproofing
- Heavy weight may require assistance to move
Best for: CPA offices with multiple employees needing quick, secure access to high-value assets in a fire event
Not ideal for: Small offices or spaces where frequent relocation is necessary, due to its weight and size
- Capacity:10 cu. ft.
- Fire Resistance:1700°F for 35 minutes
- Weight:85 pounds
- Fingerprint Capacity:29 fingerprints
- Locking Bolts:7*28mm heavy-duty steel
- Material:Steel shell with fireproof insulation
Our verdict“Ideal for offices requiring rapid, multi-user access with top-tier fire protection in a secure, heavy-duty safe.”
SentrySafe Waterproof and Fireproof Alloy Steel Digital Safe Box, 1.23 Cubic Feet
This SentrySafe provides a compact yet secure solution, combining fire and water resistance in a 1.23 cubic foot steel safe. Its digital keypad with secondary key lock offers convenient, quick access, especially compared to dial-only safes like the SentrySafe Black Fireproof Waterproof Floor Safe. The sturdy steel construction and pry-resistant bolts enhance security, while interior lighting simplifies access in low-light conditions. However, its weight and size can be cumbersome for frequent handling, and it doesn’t include waterproof features beyond fireproofing. The door’s clearance requirement could be an obstacle in tight spaces, but for offices needing reliable, electronic-controlled security, it hits the right balance.
Pros:- Provides both fire and water protection
- Secure digital keypad with secondary lock
- Interior light for easy access
Cons:- Heavy and bulky to move
- Batteries required for operation
- Door clearance needs consideration in tight spaces
Best for: Offices that prioritize compact, electronic access with fire and water protection for critical documents or electronics
Not ideal for: High-traffic areas requiring frequent move or large capacity needs, due to its size and weight
- Capacity:1.23 cubic feet
- Exterior Dimensions:17.8 x 16.3 x 19.3 inches
- Interior Dimensions:12.6 x 11.9 x 13.8 inches
- Fire Resistance:1 hour at 1700°F
- Waterproof Duration:24 hours in water up to 8 inches deep
- Locking Mechanism:Digital keypad with secondary key lock
Our verdict“Best for offices seeking a reliable, electronic-access safe that balances security and ease of use in a compact form.”
Hollon HS-750E 2-Hour Fireproof Home/Office Safe, 2.43 cu. ft., Electronic Keypad Lock
This model stands out for its robust 2-hour fire protection combined with impact resistance, making it ideal for safeguarding critical CPA documents and digital backups. Compared to the Hollon HS 880E, the HS-750E offers a larger interior capacity and adjustable shelves, which are crucial for organizing multiple files and devices. Its electronic keypad lock supports up to four users, providing flexible access control in an office environment. However, its size and weight may demand secure installation, and the electronic lock requires periodic battery changes. This pick makes the most sense for offices needing both fire and impact resistance with multi-user access.
Pros:- Provides 2-hour fire and impact resistance for comprehensive protection
- Supports multiple users via electronic keypad for flexible access
- Water-resistant design safeguards against smoke and water damage
- Interior adjustable shelves enable versatile organization
Cons:- Large size and weight may complicate secure installation
- Electronic lock requires battery replacements over time
Best for: CPA offices needing versatile, high-capacity storage with multi-user access and impact resistance
Not ideal for: Small practices or remote setups where minimal space and easy mobility are priorities
- Interior Dimensions:21 1/4”(H) x 15 1/3”(W) x 13 4/75”(D)
- Exterior Dimensions:27”(H) x 21”(W) x 20 1/8”(D)
- Capacity:2.43 cu. ft.
- Fire Resistance:2 hours
- Impact Rating:30 foot impact rated
- Locking Mechanism:3-way locking chrome bolt work, electronic keypad lock
Our verdict“This safe offers a well-rounded combination of fire, impact, and water resistance, ideal for medium to large CPA offices with multiple users.”
2026 Fireproof Safe 1700°F 35-Minute Protection
This safe excels in fire protection, withstanding temperatures up to 1700°F for 35 minutes, making it suitable for those prioritizing rapid, high-temperature fire resistance. Unlike the Hollon HS-750E, which offers longer fire protection, this model’s shorter duration might be a tradeoff for lighter weight and easier placement. Its robust steel construction and secure locking bolts add theft deterrence, while the digital keypad and override keys support quick access during emergencies. The main tradeoff involves its relatively limited fire duration compared to the 2-hour options, which might be insufficient in some fire scenarios. This safe makes the most sense for offices where quick access during a fire is critical and space is limited.
Pros:- Provides high-temperature resistance up to 1700°F for 35 minutes
- Robust anti-theft steel construction with secure locking bolts
- Multiple access options including digital keypad and override keys
- Removable shelves and interior LED light for organization
Cons:- Limited fire duration compared to 2-hour safes like Hollon HS-750E
- Heavier than smaller safes, requiring secure placement
- Complex setup may be needed for installation
Best for: CPA practices seeking rapid fire protection with digital access and minimal footprint
Not ideal for: Offices needing prolonged fire resistance beyond 35 minutes or with high-value digital assets requiring longer protection
- Fire Resistance:1700°F for 35 minutes
- Material:Cold-rolled steel
- Weight:30 lbs
- Capacity:2.0 cu.ft.
- Exterior Dimensions:13.78″W × 12.2″D × 14.6″H
- Locking Bolts:3 solid steel bolts (25mm)
Our verdict“This safe delivers quick, effective fire protection suitable for offices with space constraints and digital access needs.”
Master Lock Black Premium Fireproof and Waterproof Safe with Combination Dial, 1.23 cu-ft
This option is ideal for offices needing protection against both fire and water, enduring 2 hours at 1850°F and submerged for 24 hours in water. Compared to the Hollon HS-750C, which relies on a dial lock, the Master Lock offers a combination dial that can be more reliable in environments where electronic locks might fail. Its waterproof feature is particularly useful in flood-prone areas, although protection is limited to 5 inches of water depth. Its weight and mechanical lock make it less convenient for frequent access but highly reliable in extreme conditions. The main tradeoff involves no digital access and limited water protection depth, which might matter in specific scenarios. This safe is best for offices in flood zones where dual fire and water resistance are priorities.
Pros:- UL Classified for 2 hours at 1850°F fire resistance
- Waterproof for 24 hours in up to 5 inches of water
- Durable steel construction with pry-resistant hinge bar
- Bolt-down hardware for added security
Cons:- No digital lock option, only combination dial
- Limited water protection depth (up to 5 inches)
- Heavy and challenging to relocate
Best for: CPA offices in flood-prone areas requiring durable, fireproof, and waterproof protection with mechanical access
Not ideal for: Offices needing quick digital access or those with limited space for heavy safes
- Capacity:1.23 cubic feet
- Fire Resistance:UL Classified for 2 hours at 1850°F
- Waterproof Duration:24 hours

Hollon Safe HS-750C 2-Hour Fireproof Office Safe, Gray
The Hollon HS-750C is a large, heavy-duty safe with a 2-hour fire rating, making it an excellent choice for securing multiple essential documents and valuables in an office setting. Its large capacity and durable construction surpass lighter safes like the Master Lock in terms of robustness, though it lacks an electronic lock, relying instead on a dial. This makes it less convenient for users who prefer quick digital access but provides peace of mind in high-security environments. Its weight of nearly 300 pounds means it’s not suitable for frequent repositioning, but it ensures maximum security from theft. This safe is best suited for offices prioritizing long-term, high-security protection over ease of access.
Pros:- Fireproof for 2 hours, protecting critical documents
- Large interior capacity accommodates multiple valuables
- Heavy-duty construction enhances security
- Reliable dial lock with proven durability
Cons:- Very heavy and difficult to move without assistance
- No electronic lock for quick access
- Limited flexibility in placement due to weight
Best for: Large CPA firms or offices that need maximum security and long-duration fire protection with infrequent access

- Interior Dimensions:21-1/4in x 15-1/3in x 13-4/7in
- Capacity:2.43 cubic feet
