There are only two types of companies, it is commonly said: those that have been hacked, and those that just don’t know it yet.
IBM, the computing giant, wants to get rid of both. The company said Monday that it has achieved a breakthrough in security technology that will allow every business, from banks to retailers to travel-booking companies, to encrypt their customer data on a massive scale — turning most, if not all, of their digital information into gibberish that is illegible to thieves with its new mainframe.
“The last generation of mainframes did encryption very well and very fast, but not in bulk,” Ross Mauri, general manager of IBM’s mainframe business, said in an interview. Mauri estimates that only 4 percent of data stolen since 2013 was ever encrypted.
