Personal data encryption software comes in more shapes than most buyers expect — some options are programs that scramble files on your existing devices, while others are hardware-encrypted drives or secure operating systems on a stick. After comparing nine popular options, the Tails Linux Persistent Bootable USB stands out as the best overall pick for serious privacy because it encrypts your entire working environment rather than individual files. For buyers who mainly need to carry sensitive documents safely, the iStorage datAshur Personal2 offers the strongest certified hardware encryption, while the Secure 32GB Encrypted USB 3.0 Flash Drive delivers similar protection at a friendlier price. The main tradeoff in this category is convenience versus security: software-based tools are flexible but rely on your possibly compromised computer, whereas hardware-encrypted drives cost more per gigabyte and secure bootable systems demand a learning curve. Read on for the full breakdown, including who each option suits and who should skip it.
Key Takeaways
- The single biggest dividing line in this lineup is where the encryption happens: hardware-encrypted drives (IronKey, datAshur, Integral, Secure 32GB) keep decryption off your computer entirely, while software tools like Private Browser & Password Manager depend on the security of the host machine.
- Tails won best overall because it encrypts the whole working session, not just files — but it requires a willingness to reboot into Linux, which rules it out for casual users.
- Two products in this roundup aren’t encryption at all in the traditional sense: TunnelBear protects data in transit (network-level), and Secure Data Wipe destroys data rather than protecting it — they’re complements, not substitutes.
- Certified hardware (FIPS-validated chips in the datAshur and IronKey) costs roughly double per gigabyte versus uncertified encrypted drives; that premium only pays off if you face compliance requirements or targeted theft risk.
- PIN-pad drives like the datAshur Personal2 work across any OS with no software install, which made them the most versatile pick for people who move between locked-down work PCs and personal machines.

More Details on Our Top Picks
Private Browser & Password Manager Software Portable
Most encrypted drives in this roundup protect files at rest, but this option takes a different angle: it bundles a private browser and password manager onto a 32GB USB stick so your online activity stays protected on any Windows machine you borrow. For travelers or anyone using shared work computers, that combination solves a problem a drive like the Kingston IronKey VP50 doesn’t address — it guards credentials and browsing sessions, not just stored documents. The tradeoff is real, though: it’s Windows-only, and if you lose the drive, everything on it goes with it. Compared with the Tails Linux bootable USB, which offers deeper anonymity but demands more technical comfort, this pick makes more sense for casual users who want plug-in privacy without a learning curve.
Pros:- Combines private browsing and password management in one portable device
- 32GB of encrypted storage for sensitive files alongside the software
- Simple plug-and-use setup with no installation required
- Ideal for use on shared or public Windows computers
Cons:- Windows-only with no cross-platform support
- Losing the USB drive means losing all stored credentials and data
- Encryption details are vague compared with hardware-encrypted rivals like the IronKey
Best for: Travelers and remote workers who use shared or borrowed Windows PCs and want browsing and password protection on the go
Not ideal for: Mac or Linux users, or anyone who needs cross-platform encrypted file storage — this is locked to Windows
- Storage Capacity:32GB USB drive
- Platform:Windows
- Encryption:Advanced encryption capability
- Key Features:Private browsing, anonymous browsing, password management
- Portability:Pocket-sized USB drive, no installation
- Use Case:Travel, work, and shared-PC privacy
Our verdict“Buy this if your main concern is staying private on other people’s Windows computers rather than encrypting your own files at home.”
Kingston IronKey Vault Privacy 50 16GB Encrypted USB
This is the security heavyweight of the encrypted-drive group. With XTS-AES 256-bit hardware encryption, brute-force and BadUSB attack protection, and TAA compliance, it meets procurement standards most consumer drives can’t touch — something the Integral Secure 360-C, which also uses 256-bit AES, doesn’t claim. The multi-password and passphrase modes let admins and users split access, which matters if a drive is lost or a password is compromised. The catch is capacity: 16GB fills up fast if you’re moving video or backups, and the wealth of security options can feel overwhelming compared with simpler rivals. If you need certified-level protection over raw space, this stands out; if you just want everyday file encryption, the iStorage datAshur offers a friendlier path at similar security levels.
Pros:- Hardware-based XTS-AES 256-bit encryption with no software dependency
- Protection against brute-force and BadUSB attacks
- Multi-password, passphrase, and dual read-only modes for flexible access control
- TAA compliance for government and enterprise procurement
Cons:- Only 16GB of storage, limiting it to documents and small archives
- Advanced password management features add setup complexity for average users
Best for: Government contractors, enterprise users, and compliance-driven professionals who need TAA-compliant hardware encryption
Not ideal for: Anyone moving large files or backups — 16GB is tight, and casual users may find the password options confusing
- Capacity:16GB
- Encryption:XTS-AES 256-bit hardware
- Security Features:Brute Force and BadUSB protection, multi-password, passphrase mode, dual read-only
- Compliance:TAA Compliant
- Form Factor:Encrypted USB flash drive
- Best Use:Government, enterprise, and compliance environments
Our verdict“This pick makes the most sense for buyers whose security requirements include compliance standards, not just encryption.”
Integral Secure 360-C 16GB USB-C Encrypted Flash Drive
If the IronKey is the compliance pick, this is the straightforward one. The 360-C keeps things simple: 256-bit AES encryption, a USB-C connector, and compatibility across Mac, MacBook, PC, and laptops without the layered password policies that make Kingston’s drive feel enterprise-heavy. For someone who wants to encrypt tax documents or client files and move them between a MacBook and a PC, that cross-platform reach is the real selling point — the IronKey and the Private Browser drive both fall short for Mac households. You give up the attack-protection features and government compliance of pricier rivals, and 16GB caps how much you can protect at once. Think of it as a solid everyday lockbox rather than a vault: dependable, affordable, and refreshingly uncomplicated next to feature-packed alternatives.
Pros:- 256-bit AES encryption at an accessible price point
- Works across Mac, MacBook, PC, and laptops
- USB-C connector fits modern laptops without adapters
- Straightforward operation with minimal setup
Cons:- 16GB capacity limits storage of large files and backups
- Lacks the advanced attack protection and compliance certifications of premium drives
Best for: Students, freelancers, and home users who want simple cross-platform encrypted storage for everyday files
Not ideal for: Users with large media libraries or anyone who needs attack protection and enterprise compliance features
- Storage Capacity:16GB
- Encryption:256-bit AES
- Connector Type:USB-C
- Compatibility:Mac, MacBook, PC, Laptop
- Form Factor:Encrypted USB flash drive
- Skill Level:Beginner-friendly
Our verdict“A sensible pick for buyers who prioritize affordability and Mac compatibility over enterprise-grade safeguards.”
MINI Pro External Encrypted SSD (512GB)
When 16GB flash drives aren’t enough, this is the step up. The MINI Pro pairs 512GB of SSD storage with AES256-XTS hardware encryption, a decoy PIN mode, and a hardware write-blocker — a feature none of the flash drives here offer, which blocks malware from writing to the drive when you plug into an untrusted machine. Its bootable virtual optical drive function also makes it a recovery and rescue tool, something closer in spirit to the Tails Linux bootable USB than to the Integral 360-C. Speeds of 500 MB/s mean encrypted backups finish in minutes, not hours. The tradeoff: all this capability comes with a steeper learning curve and a premium price. Compared with the Kingston IronKey, you trade compliance certifications for capacity and versatility — a better deal for power users than for procurement managers.
Pros:- 512GB capacity dwarfs the 16GB flash drives in this roundup
- AES256-XTS hardware encryption with PIN and decoy PIN protection
- Hardware write-blocker guards against malware on untrusted computers
- Bootable virtual ODD/HDD plus 500 MB/s read speeds for fast recovery workflows
Cons:- Complex setup compared with plug-and-play flash drives
- Requires USB-C equipped devices
- Premium price for features many everyday buyers won’t need
Best for: Power users, IT professionals, and privacy-focused users who need large encrypted capacity plus boot and recovery capability
Not ideal for: Casual users who just want to encrypt a few documents — the advanced features add cost and complexity they won’t use
- Storage Capacity:512GB
- Interface:USB 3.1 Gen 1, USB Type-C
- Read Speed:500 MB/s
- Data Transfer Rate:5 Gbps
- Encryption:AES256-XTS hardware with PIN protection
- Additional Features:Bootable virtual ODD/HDD, hardware write-blocker, decoy PIN
- Origin:Made in Korea
Our verdict“Worth the investment if you need serious capacity, speed, and recovery tools in one encrypted package; overkill for basic document protection.”
Secure Data Wipe USB – Hard Drive Eraser Tool
Encryption protects data while it lives; this tool handles the other end of the lifecycle — making data permanently unrecoverable. Using industry-standard sanitization tools like DBAN, ShredOS, and Secure Erase, it boots from USB and wipes HDDs and SSDs clean, which matters enormously before selling, donating, or decommissioning a computer. None of the encrypted drives in this lineup do this; even the Kingston IronKey or iStorage datAshur only protect data on the drive itself, not what’s left on your old laptop’s internal disk. The MINI Pro is its closest cousin in technical demands — both require comfort with boot menus and disk utilities. That’s the main barrier: this isn’t a one-click solution, and choosing the wrong wipe target can be catastrophic. For IT staff and careful sellers, though, it’s an inexpensive insurance policy against data recovery by the next owner.
Pros:- Uses industry-standard tools including DBAN, ShredOS, and Secure Erase
- Bootable plug-and-play design requires no software installation
- Broad compatibility with Windows, Linux, and BIOS/UEFI machines
- Makes data permanently unrecoverable before resale or disposal
Cons:- Requires real technical knowledge to use safely
- Single-purpose tool with no encryption or storage features
- No guidance or included documentation mentioned for beginners
Best for: IT professionals and individuals selling or donating old computers who need certified-level data destruction
Not ideal for: Non-technical users — selecting the wrong drive or wipe method can destroy data you meant to keep
- Type:Bootable USB drive
- Compatibility:Windows, Linux, BIOS & UEFI PCs and laptops
- Purpose:Data sanitization and hard drive erasure
- Tools Used:DBAN, ShredOS (Nwipe), Secure Erase
- Setup:Plug & Play, no installation
- Best Use:Wiping drives before resale, donation, or disposal
Our verdict“A must-have before you sell or recycle a computer — but only if you’re comfortable with boot tools and disk utilities.”
TunnelBear VPN Software, 1-Year Subscription, Unlimited Data and Devices
Unlike every other pick in this roundup, TunnelBear protects data in transit rather than at rest — and that distinction matters when choosing personal encryption tools. This option stands out for its unlimited device allowance, which is rare at this price and covers a whole household of laptops, phones, and tablets under one subscription. One-click setup makes it far friendlier than the Tails Linux USB, which demands real technical fluency. Compared with hardware like the iStorage datAshur Personal2, there’s no physical object to lose or break, but that cuts both ways: your protection depends entirely on account credentials. The one-year term locks you into a single commitment, and configuration options are limited to what the app exposes.
Pros:- Unlimited data and devices under a single subscription
- Servers in 47 countries with fast connection speeds
- One-click setup that takes minutes rather than hours
- Strong encryption paired with a strict no-logs policy
Cons:- Only encrypts traffic in transit, not files stored on your device
- Fixed one-year subscription with no shorter commitment option
- Requires internet connectivity for activation and ongoing use
Best for: Households and individuals who want encrypted internet traffic and private browsing across all their devices without managing hardware
Not ideal for: Anyone protecting large files at rest — a VPN doesn’t encrypt your stored documents the way the Secure 32GB flash drive or an encrypted SSD does
- Duration:1 year
- Devices:Unlimited
- Server Locations:47 countries
- Encryption:Strong encryption
- Logging Policy:No logs
- Setup:One-click
Our verdict“This makes the most sense for buyers whose priority is private browsing rather than encrypted file storage.”
Secure 32GB Encrypted USB 3.0 Flash Drive – 256-bit Hardware Encryption
For buyers who want hardware encryption without a premium price, this 32GB drive delivers the essentials well. The 256-bit AES XTS encryption lives on the drive itself, so it works across Windows, Mac, and Linux with no software installation — a real advantage over software-only solutions like the Private Browser & Password Manager, which depends on host applications. Transfer speeds up to 480MB/s read outpace the iStorage datAshur Personal2’s 116MB/s, though the zinc alloy shell is heavier in a pocket. The tradeoff that deserves attention: ten wrong password attempts trigger a factory reset, which is excellent anti-theft behavior but brutal if your memory fails you. Capacity is also modest next to the MINI Pro SSD’s 512GB.
Pros:- Military-grade 256-bit AES XTS hardware encryption built into the drive
- Fast USB 3.0 read speeds up to 480MB/s
- Rugged zinc alloy shell resists scratches and corrosion
- Works across Windows, Mac, Linux, and embedded systems with no software
Cons:- Factory reset after 10 incorrect password attempts destroys all data
- 32GB capacity fills quickly with large files
- No bundled software or extras like password managers or remote wipe
Best for: Budget-conscious professionals who need to move sensitive documents between computers securely and don’t need bulk storage
Not ideal for: Forgetful users or anyone carrying large media libraries — the reset-on-failure policy and 32GB limit are real constraints
- Storage Capacity:32GB
- Encryption:256-bit AES XTS hardware
- Interface:USB 3.0
- Read Speed:up to 480MB/s
- Write Speed:up to 160MB/s
- Material:Zinc alloy
- Compatibility:Windows, Mac, Linux, embedded systems
Our verdict“This is the smart pick for secure file portability on a budget, provided you never lose your password.”
iStorage datAshur Personal2 64 GB Secure Flash Drive with Hardware Encryption
Where the Secure 32GB drive relies on password entry through the host computer, the datAshur Personal2 puts a physical keypad on the drive itself, unlocking with an onboard PIN before it even appears as a USB device. That matters on compromised public machines — keyloggers can’t capture a PIN typed on the drive. This model is better suited to lawyers, journalists, and compliance-driven users who need protection independent of the host operating system. Doubling the capacity to 64GB gives it breathing room the smaller drive lacks, and the PIN approach avoids the unforgiving reset-after-10-attempts behavior entirely. The compromises: write speeds of 135MB/s trail cheaper rivals, and entering a PIN every session adds friction that casual users may find tiresome.
Pros:- Onboard PIN authentication immune to host-based keyloggers
- AES-XTS 256-bit hardware encryption with no software required
- 64GB capacity doubles the cheaper 32GB options in this roundup
- Broad operating system compatibility out of the box
Cons:- Read speeds of 116MB/s lag well behind cheaper competitors
- PIN entry adds friction to every access session
- Capacity still modest for anyone working with large archives
Best for: Professionals handling confidential client files who need tamper-proof, host-independent access control on shared or public computers
Not ideal for: Everyday casual users who value convenience — PIN entry before every use feels slow compared with password-based drives
- Memory Storage Capacity:64 GB
- Hardware Interface:USB 3.0
- Write Speed:Up to 135MB/s
- Read Speed:116MB/s
- Connectivity:USB Type A
- Hardware Encryption:AES-XTS 256-bit
- Authentication:Onboard PIN keypad
Our verdict“Worth the premium for anyone whose threat model includes untrusted computers; overkill for home users.”
Tails Linux Persistent Bootable USB with 32GB Storage
This is the most radical privacy tool in the lineup — it doesn’t just encrypt files, it turns any computer into a private, anonymous machine that leaves no trace on the host. Booting Tails from the drive routes all traffic through Tor, a level of protection TunnelBear’s VPN can’t match since a VPN still sees your traffic. The encrypted persistent storage lets you save files and settings across sessions while keeping everything else wiped on shutdown. Compared with the iStorage datAshur, which secures a folder of documents, this secures your entire computing environment. The price is steep in usability: expect a learning curve around boot menus, Tor’s slower browsing, and compatibility limited to what Tails supports. Dual USB-A and USB-C connectors are a thoughtful touch for modern laptops.
Pros:- Routes all internet traffic through Tor for anonymity beyond what a VPN offers
- Encrypted persistent storage preserves files and settings across sessions
- Leaves zero footprint on the host computer after shutdown
- Dual USB-A and USB-C connectors work with nearly any modern machine
Cons:- Demands real technical knowledge to boot and configure correctly
- Locked to the Tails Linux environment with limited software compatibility
- Tor routing noticeably slows browsing, especially on older hardware
Best for: Privacy-focused users, journalists, and activists who need an entire anonymous computing environment rather than just encrypted storage
Not ideal for: Beginners and everyday users — the technical setup and Tor-slowed performance make TunnelBear or a simple encrypted flash drive far more practical
- Storage Capacity:32GB
- Connectivity:USB-A & USB-C
- Operating System:Tails Linux (bootable)
- Persistent Storage:Encrypted
- Network Privacy:Tor routing
- Session Modes:Temporary and persistent
Our verdict“The right choice only for those who need whole-system anonymity; everyone else should stick with simpler encrypted storage.”
How We Picked
I judged every option against one question: how well does it protect personal data from realistic threats — lost or stolen devices, snooping on shared computers, and interception on public networks? That broke down into five criteria. First, encryption strength and independence: AES-256 handled by dedicated hardware ranks above software encryption running on a potentially compromised machine. Second, usability, because encryption that’s too awkward to use daily gets abandoned, leaving data exposed. Third, portability and compatibility across operating systems and locked-down work computers. Fourth, capacity and value, comparing cost per gigabyte and whether the price matches the threat level. Fifth, specialist capabilities like secure wiping or full-session anonymity that solve problems the other products can’t.
The ranking reflects how many of those criteria each product satisfies and for whom. Tails tops the list on sheer protection scope despite its steeper learning curve; the iStorage and Secure 32GB drives follow as the best file-carrying tools at two price points; and single-purpose tools like the Secure Data Wipe USB rank lower overall but earn their place for the specific jobs nothing else in the lineup does.
Factors to Consider When Choosing Personal Data Encryption Software
Before spending money on any of these products, it helps to understand what you’re actually protecting and from whom. The right choice depends less on specs and more on your threat model.Hardware vs. Software Encryption
This is the decision that shapes everything else. Software encryption runs on your computer, which means it inherits every weakness of that computer — keyloggers, screen capture, malware, and shoulder-surfing can all defeat it. Hardware encryption lives on a dedicated chip inside the drive, so your password is validated by the device itself and never touches the host machine. The catch: hardware-encrypted drives cost considerably more per gigabyte and are single-purpose — they protect what’s on the drive, nothing else. If your laptop is compromised, a software vault on that laptop is compromised too, while a PIN-authenticated drive is not. Buy software tools when you trust your device and need flexibility; buy hardware when the drive might be lost or stolen.
Certifications Matter More Than Marketing
Nearly every encrypted drive on the market claims “AES-256,” but that claim means little without independent validation. Look for FIPS 140-2 or 140-3 validation, which confirms the encryption implementation survived government-level scrutiny. The gap between the iStorage datAshur and cheaper uncertified drives in this roundup isn’t the algorithm — it’s the tamper resistance, brute-force lockouts, and supply-chain verification behind it. A common mistake is buying a no-name “encrypted” drive where the encryption is actually a hidden partition with a password prompt, trivially bypassed. For tax records or personal photos, uncertified may be fine. For client data, medical records, or anything with legal exposure, the certification premium is cheap insurance.
Match Capacity and Speed to Real Usage
Encrypted storage is dramatically more expensive per gigabyte than ordinary drives, so overbuying capacity wastes real money. A 16GB encrypted drive holds roughly 3,000 documents or a few thousand photos — plenty for most personal use — while 64GB or a 512GB encrypted SSD only makes sense for large media archives or portable system images. Speed matters if you’ll work directly from the drive: USB 3.0 flash drives handle document work comfortably, but editing video or running a bootable environment from a slow drive becomes painful fast. The MINI Pro encrypted SSD exists precisely because flash drives bottleneck at sustained transfers. My advice: audit what you’d actually carry encrypted, then buy the smallest tier that fits with room to grow.
Don’t Confuse Encryption With Network Privacy
Buyers frequently buy a VPN believing it encrypts their files, or buy an encrypted drive believing it hides their browsing — neither is true. A VPN like TunnelBear encrypts data in transit, protecting you on public Wi-Fi and masking your IP, but it does nothing for a stolen laptop. An encrypted drive protects data at rest but leaves your network activity fully visible. A password manager protects credentials but not documents. Many people realistically need two of these categories layered together. The mistake to avoid is treating any single product as a complete privacy solution and developing false confidence. Figure out whether your risk is data at rest, data in motion, or credential theft, and buy for that specific gap.
Plan for Recovery and Loss
Strong encryption is a one-way door: forget the PIN on a hardware-encrypted drive and the data is gone, with no manufacturer reset possible — that’s a feature, not a flaw. Before committing to any of these products, decide what happens when you lose the password, the drive fails, or you’re traveling and the device is confiscated or damaged. Keep an encrypted backup of anything irreplaceable stored separately from the original. Also check whether the product has admin recovery features (common on corporate-grade drives, absent on personal ones) and whether the drive self-destructs its keys after a set number of wrong attempts. That brute-force lockout is excellent against thieves but brutal against your own foggy memory — write the PIN down somewhere physically secure, not in your email.
Frequently Asked Questions
Is a hardware-encrypted USB drive really safer than free software encryption like BitLocker or VeraCrypt?
For most realistic personal threats, yes, and the reason comes down to where the password is checked. Software encryption types your password into the operating system, so malware, a keylogger, or even a shared computer’s logging can capture it. A hardware-encrypted drive with an onboard keypad — like the iStorage datAshur Personal2 — validates your PIN on the chip itself, so the host machine never sees the key. The tradeoff is cost and capacity: you’ll pay several times more per gigabyte than an unencrypted drive plus free software. If your own laptop is trustworthy and never leaves home, software encryption is a perfectly reasonable choice. If the drive travels in a bag or briefcase, hardware wins clearly.
What does the Tails bootable USB actually protect against, and is it overkill for everyday use?
Tails protects the entire computing session: it boots its own operating system from the USB stick, uses your computer’s RAM instead of its hard drive, and leaves no trace on the machine when you shut down. That makes it uniquely strong against a compromised or monitored computer — something no encrypted drive or password manager can claim. The cost is workflow: you have to reboot into it, it runs Linux applications, and everything feels slower and less convenient than your normal desktop. For journalists, activists, or anyone using an untrusted machine to access sensitive accounts, it’s the right tool. For encrypting your photo library at home, it’s absolutely overkill, and a hardware-encrypted drive will serve you far better.
Do I need a VPN if I already have encrypted storage?
The two solve entirely different problems, and many people need both. Encrypted storage protects data at rest — files sitting on a drive that might be lost or stolen. A VPN protects data in motion — the traffic between your computer and the internet, which matters most on public Wi-Fi at cafes, airports, and hotels. Your encrypted USB does nothing to stop someone on the same network observing which sites you visit, and your VPN does nothing to protect the files on a stolen laptop. If you work remotely from public networks, a VPN like TunnelBear with unlimited data covers a genuine gap. If you only ever use your home network, encrypted storage is the higher priority.
Why would I buy a secure data wipe tool instead of just formatting a drive?
Formatting doesn’t erase data — it just removes the index that tells the system where files live, and standard recovery software can rebuild much of it. Before you sell, donate, or recycle a computer or drive, a proper wipe tool overwrites every sector to a recognised standard, which matters enormously if the drive held tax documents, medical records, or passwords. The dedicated wipe USB also solves a chicken-and-egg problem: you can’t run wiping software from the drive you’re wiping. If you’re disposing of hardware that once held sensitive personal data, the one-time cost is trivial compared to the risk of identity theft. If you only ever hand down devices within your family, a simple format is usually sufficient.
Are the cheaper uncertified encrypted drives worth it, or should I pay extra for FIPS-validated hardware?
It depends on who you’re defending against. Against an opportunistic thief or a curious coworker, a well-built uncertified drive with genuine AES-256 hardware encryption — like the Secure 32GB drive in this lineup — provides real protection at a much lower price. FIPS-validated drives such as the IronKey and datAshur add tamper-evident packaging, epoxy-potted components, and defence against sophisticated physical and electronic attacks that ordinary criminals simply don’t perform. Where certification becomes non-negotiable is compliance: many employers, healthcare contexts, and legal situations specifically require FIPS-validated storage. For purely personal use with moderate sensitivity, save the money. If losing the drive would create legal or professional exposure, spend it.
Conclusion
After comparing all nine options, the right pick comes down to what you’re protecting and how you work. For best overall protection, the Tails bootable USB encrypts your entire session and leaves no trace on any computer you use — unmatched if you’ll accept the reboot. The best value is the Secure 32GB Encrypted USB 3.0 Flash Drive, which delivers genuine 256-bit hardware encryption at a price that makes daily use painless. For the best premium option, the iStorage datAshur Personal2 justifies its cost with an onboard keypad, FIPS-grade construction, and universal compatibility that works even on locked-down machines with no software install. Beginners should start with the Integral Secure 360-C — it’s affordable, USB-C native, and simple enough that you won’t abandon it. Specific needs round out the lineup: the MINI Pro encrypted SSD for speed-critical large archives and write-blocked forensic work, the Secure Data Wipe USB for safely disposing of old drives, TunnelBear for protecting data on public networks, the Kingston IronKey VP50 for a balance of certification and value in a corporate setting, and the Private Browser & Password Manager for credential protection on shared computers. Whatever you choose, the worst decision is no decision — unencrypted personal data is the one option this roundup can’t recommend.
