By 2020, 200 billion devices and objects — cars, phones, medical instruments, manufacturing machines, home appliances — could be talking to each other via the Internet of Things and the Industrial Internet of Things. That’s a lot of stuff for crafty criminals to hack, corrupt and infiltrate — and it’s multiplying all the time. In fact, the worldwide tally for cybercrime damages by 2021 is predicted to be $6 trillion

As collectors and storers of data on a grand scale, businesses are especially ripe for targeting. IBM president and CEO Ginni Rometty thinks so, too.

“Cybercrime,” she has said, “is the greatest threat to every company in the world.”

It goes without saying that sophisticated cybersecurity is more crucial than ever, and fortunately, there are plenty of cybersecurity companies ready to help.
