Amazon.com (NASDAQ:AMZN) is launching a new offering to increase cloud security for its Amazon Web Services customers.

CloudHSM is a hardware security module that provides secure key storage and a set of cryptographic operations. Customers can encrypt and decrypt data and maintain full control of the keys and cryptographics. Amazon says the hardware is designed to meet a number of international and U.S. government standards.

The service is available for an one-time upfront fee of $5,000 per HSM, or an hourly rate of $1.88 per hour. It's currently available in the company's U.S. East and EU West regions -- specifically, Northern Virginia and Ireland. Expansion will continue throughout 2013.
