Most encrypted USB drives put the security in software — which means the security lives on the host machine, not the drive. The iStorage datAshur PRO takes a different approach. Authentication happens on the drive itself, before it ever connects to a computer. Enter your PIN on the built-in alphanumeric keypad, the drive unlocks, and only then does it appear as a USB mass storage device. Pull it out, and it locks instantly. No password manager, no software, no host dependency.

The encryption is AES-XTS 256-bit, implemented entirely in hardware by a dedicated secure microprocessor. The encryption key is never exposed to the host and is never stored in an unencrypted state. FIPS 140-2 Level 3 certified for the full device — the same standard required for classified government systems — and validated to NLNCSA DEP-V and NATO Restricted, the datAshur PRO is cleared for use in environments where most encrypted drives are not even considered. The epoxy-sealed internals make physical tampering effectively impossible without destroying the components themselves.

Key Features

  • FIPS 140-2 Level 3 certified — full device certification
  • NLNCSA DEP-V and NATO Restricted validated
  • AES-XTS 256-bit full disk hardware encryption — always on, no software required
  • PIN authenticated — 7 to 15 digit alphanumeric PIN, independent User and Admin PINs
  • IP57 rated — dust-proof and water-resistant to 1m for 30 minutes
  • MIL-STD-810F military-grade durability tested
  • Tamper-proof and tamper-evident — epoxy-sealed internals
  • Self-destruct PIN — instantly and permanently wipes all data
  • USB 3.2 Gen 1 — 170 MB/s read, 146 MB/s write
  • Built-in rechargeable battery — PIN entry without a host required
  • Immune to BadUSB attacks — digitally-signed firmware
  • Read-only (write protect) mode — configurable by Admin
  • Works on any device with a USB port — no drivers, OS independent
  • Available in 4GB, 8GB, 16GB, 32GB, 64GB, 128GB and 256GB
  • Designed and developed in the UK | 3-year warranty

The datAshur PRO is built around a rechargeable Li-Polymer battery, which means the PIN keypad operates independently of the host — you can unlock the drive before plugging it in, handy for shared or restricted workstations. The aluminium sleeve provides structural protection and the IP57 rating handles dust, dirt, and submersion to 1 metre for 30 minutes. MIL-STD-810F testing rounds out the physical durability story. This is a drive that goes in a bag, onto a production floor, or into a field kit without concern.

For enterprise deployment, the Admin and User PIN separation gives IT departments full control — set PIN complexity requirements, configure read-only mode, assign one-time recovery PINs, and reset User access without ever compromising the Admin PIN or the data. GDPR, HIPAA, SOX, CCPA, and DORA compliance requirements for hardware-encrypted removable media are satisfied entirely in hardware, with no cloud dependency and no subscription.

Product Q&A

Q: What happens if I enter the wrong PIN too many times?

A: After 10 consecutive incorrect User PIN entries, the User PIN is deleted and the drive can only be unlocked via the Admin PIN or a one-time recovery PIN. If the Admin PIN is entered incorrectly 10 consecutive times, all data, PINs, and the encryption key are permanently and irreversibly destroyed. The Admin can configure the User lockout threshold from 1 to 10 attempts.

Q: Why does the datAshur PRO have a built-in battery?

A: The rechargeable Li-Polymer battery powers the PIN keypad independently of the host computer. This means you can authenticate and unlock the drive before plugging it into a workstation, which is particularly useful on shared, locked-down, or kiosk machines where USB interactions may be monitored or restricted. The battery charges via the USB port during normal use.

Q: Does this require any software or drivers?

A: No. The datAshur PRO is entirely hardware-based. Authentication happens on the drive before it connects to the host. Once unlocked, it mounts as a standard USB mass storage device on Windows, macOS, Linux, Android, Chrome OS, thin clients, zero clients, embedded systems, Citrix, and VMware — no software installation required.

Q: What do NATO Restricted and NLNCSA DEP-V mean?

A: These are government and military encryption validations beyond FIPS 140-2. NATO Restricted means the drive meets NATO's requirements for protecting information classified at the Restricted level. NLNCSA DEP-V is a Dutch National Communications Security Agency validation for encrypted storage used in sensitive government environments. These certifications make the datAshur PRO one of the few commercial USB drives approved for use across European government and defence organisations.

Q: What is the difference between the datAshur PRO and the datAshur PRO2?

A: The PRO2 adds a Common Criteria EAL5+ certified secure microprocessor (the same class used in banking smartcard chips), upgrades the IP rating to IP68, and extends the capacity range to 512GB. The PRO uses a FIPS 140-2 Level 3 certified module with IP57 and NATO/NLNCSA validations. Both use AES-XTS 256-bit hardware encryption and the same PIN authentication model. If NATO Restricted or NLNCSA DEP-V compliance is a requirement, the PRO is the correct choice; if EAL5+ microprocessor certification and IP68 are the priority, choose the PRO2.
