The Kingston IronKey™ D300S/SM USB flash drive features an advanced level of security which builds on the features that made IronKey well respected, to safeguard sensitive information. It’s FIPS 140-2 Level 3 certified, with 256-bit AES hardware-based encryption in XTS mode. An essential pillar to setting security standards, corporate policies and data loss protection (DLP) best practices. An important element in the quest for compliance with industry standards and global regulations such as the GDPR.

  • Advanced level of security that builds on the features that made IronKey well-respected
  • Available in a Managed model that requires SafeConsole or IronKey EMS1
  • Rugged and tamper-resistant casing that meets IronKey standards
  • Fast data transfers that use the latest in NAND Flash and controller technology
  • Customisable
  • Easy to use

For added peace of mind, the drive uses digitally signed firmware, making it immune to BadUSB, and it enforces complex password protection2 with minimum characteristics to prevent unauthorised access.

Encryption and decryption is done on the drive, with no trace left on the host system, and the drive locks down and reformats after 10 invalid attempts, to protect against brute force attacks.

Rugged and tamper-resistant, IronKey D300S/SM has a zinc casing and tamper-evident epoxy seal for physical security, so you can rest assured the drive will hold up, even in the most demanding situations.

Customisable, easy to use and waterproof up to 4 feet, conforming to IEC60529 IPX83. SuperSpeed (USB 3.0) technology means you don’t have to compromise speed for security.

On top of its industry-leading data protection, IronKey D300S / D300SM provides a unique serial-number and barcode printed on drive and virtual keyboard4.

Managed model

Requires SafeConsole or IronKey EMS software management system1. This allows central management of drive access and usage across thousands of drives.

Either cloud-based or on-premises, it enforces drive-specific policies, such as password strength and retry limits, and lets administrators remotely disable lost or stolen drives, recover lost passwords and more.
