"We've got to focus on security because it just doesn't stop, right? I mean, whether it be Jennifer Lawrence or whether it be Chinese hacking," Cramer said on "Squawk on the Street." "There's one company that's one step ahead of the posse and that is Palo Alto Networks."

The Santa Clara, Calif.-based company, which provides firewalls and other network security services, is Cramer's "favorite" cybersecurity stock. He praised the leadership of CEO Mark McLaughlin, who he called the "smartest man in the world right now, in terms of hacking."
"It's hard for me to see how it doesn't go to $100," he said.
