Coalfire Systems Assessment: Merchant Link’s TransactionShield and TransactionVault Reduce Merchant’s PCI Scope

June 23, 2011, Kennet Westby, President and COO

Merchants spend a lot of time and money developing IT controls programs to protect consumer credit card data. Through our work with thousands of retailers, we’ve learned that one of the best ways to contain costs and reduce risk is to keep cardholder data out of as many systems and business processes as possible. In our line of business, that’s called ‘reducing PCI scope’, since systems and processes that don’t store, process or transmit cardholder data are excluded from the controls required by the PCI DSS.

This week at the HITEC conference in Austin, Texas, hospitality professionals are coming together to discuss innovations and emerging technologies. At this event, one of our clients, Merchant Link, is releasing a white paper that summarizes an assessment that Coalfire’s Application Security team completed on their Transaction Shield and TransactionVault solutions.

TransactionShield is a point-to-point encryption (P2PE) solution that ensures that customer data is secure from the moment their credit card is swiped.  The TransactionVault tokenization solution removes customer credit card data where it would be at risk from hackers. The data is instead stored in Merchant Link’s hosted vault.  The combination of TransactionShield and TransactionVault secure both data in-flight and data at rest, and reduce the cost and effort of attaining and maintaining PCI compliance.

It was our pleasure to test these solutions and offer an independent, unbiased opinion. Our tests have confirmed that, when properly deployed, these solutions can effectively remove merchant retail POS systems from the scope of PCI DSS and provide significant risk mitigation of data compromise.

We wish Merchant Link and their customers well as they deploy these solutions.
