Ingrian Networks announced it has updated its DataSecure encryption appliance line most commonly used for credit-card encryption, adding the high-end 400 Series and discontinuing the 300 Series, while keeping the low-end 100 Series with enhancements.

The high-end DataSecure 400 Series can encrypt 100,000 credit cards per second, about twice the range of the 300 Series being discontinued, according to Ingrian's vice president of product development, Derek Tumulak. The 1ow-end DataSecure 100 Series, which in the past encrypted at about 11,000 credit cards per second, can now attain closer to 50,000 on a new generation of hardware.

In addition, Ingrian has submitted both the 100 and 400 Series of encryption appliances for lab-testing review under the U.S. government's Federal Information Processing Standard 140-2 cryptographic compliance program and the internationally accepted Common Criteria product-evaluation program.

"You have to have FIPS 140-2 and Common Criteria for government contracts now," Tumulak says.

Ingrian is seeking FIPS 140-2 cryptographic Level II for "tamper-evident certification" and the Common Criteria EAL 2, a test-review level that indicates the product works exactly according to submitted documentation.

The Ingrian encryption products have been in FIPS and Common Criteria test review at an accredited lab for close to a year and the company expects to be able to release the official results soon.

Tumulak said the Ingrian encryption devices are typically deployed close to the credit-card data sources, including file servers and mainframe. The DataSecure appliance line supports both public- and private-key encryption, and a range of algorithms, including the Advanced Encryption Standard.

The DataSecure 100 Series starts at US$15,000 and the 400 Series ranges between US$27,000 to US$35,000.
