ATLANTA — December 16, 2011 — Liaison Technologies, a global provider of secure cloud-based integration and data management services and solutions, is offering a free download of a new white paper from Securosis that answers questions on tokenization left unaddressed by the PCI Council’s “Information Supplement: PCI DSS Tokenization Guidelines” released earlier this year. Co-sponsored by Liaison and written by Securosis Analyst & CTO Adrian Lane, the new paper, titled “Tokenization Guidance: How to Reduce PCI Compliance Costs,” explains exactly how to implement tokenization to meet Payment Card Industry Data Security Standards (PCI DSS), reduce scope and lower compliance costs.

The paper is the product of hundreds of hours of research and interviews with nearly a hundred merchants, payment processors, tokenization vendors and qualified security assessors (QSAs). It provides answers to the most commonly asked questions on tokenization readers have after reviewing the PCI Council’s tokenization guidelines. Foremost among these questions: “What falls out of scope?” and “What are the audit guidelines?,” both of which the Securosis paper answers in full.

“Tokenization is highly effective for lowering both risk and the cost of PCI compliance through scope reduction, as evidenced by forward-thinking retailers that have already reaped the benefits of this relatively new data security model,” said Christopher Hale, VP Product Marketing at Liaison. “The new guide from Securosis succinctly spells out for merchants the ‘whys’ and ‘hows’ of tokenization in no-nonsense language. We encourage merchants, auditors and QSAs to download it today to clearly understand what steps they should take to start reaping the unique benefits of tokenization, as well.”

In the white paper, the author draws on his extensive research to provide sound and practical guidance to merchants on how to use tokenization to reduce scope. He also offers advice to both internal auditors going through a self-assessment questionnaire, and to external auditors. The paper includes a comprehensive tokenization audit checklist.

In April 2009, Liaison Technologies introduced Liaison Protect™ Token Manager, the industry’s first tokenization solution to combine universal Format Preserving TokenizationTM, strong encryption and unified key management in one platform-agnostic package. Liaison Protect™ Tokenization as a Service (TaaS), the first cloud-based tokenization service for national and multi-national companies that want to protect Personally Identifiable Information (PII) and Electronic Health Records (EHR), was introduced in February 2011.
