A cyber attack on JP Morgan Chase compromised about 76 million households and about 7 million small businesses. The breach was disclosed in a securities filing on Thursday. Jim Cramer says when you hear about a security breach like this, here's what you need to think: Palo Alto Networks. Cramer says the network security company is able to find the threat faster than anyone else. However what worries him is that they only have $500 million in revenues -- which leads him to question how much companies are NOT spending on security issues. He says the JP Morgan cyber attack is troubling because it says to him that every bank needs to spend much more money on cyber security than they currently are and that's why he likes Palo Alto.
