Weaknesses of mainframes, which support some 90% of all credit card transactions, often are overlooked by organizations that perceive the platforms as more secure and protected against hacking. 

According to IBM, their mainframe systems currently support 87% of all credit card transactions, nearly $8 trillion in payments a year and 29 billion ATM transactions. Ninety-two of the world's top 100 financial institutions rely on the IBM mainframe because of its ability to efficiently process huge volumes of transactions. While IBM's latest mainframe models encrypt transactional data, the vast majority in the field expose significant vulnerabilities.

New York, N.Y. and Tel Aviv, Israel-based Illusive Networks introduced Mainframe Guard which enables the inclusion of mainframe systems into an integrated deception solution architecture to protect critical business services from advanced persistent threats and other high-impact attacks.
