Safe mavens

Sony Pictures is still wincing from the massive hack that exposed hundreds of private documents, revealing not only accounting numbers, but embarrassing correspondence about some of Hollywood biggest stars.

Yet, as far as cyberattacks go, some experts say Sony got off easy -- at least on the financial side. A far different breach of customer credit card information at Target Corp. in 2013 cost the retail chain $145 million, and a lot of unhappy customers.

Losses from cyberattacks worldwide are more than a half-trillion dollars, and companies both big and small are looking for help to keep their data secure.
