Playing Koi: Palo Alto isn't saying if it will buy security start-up

Palo Alto Networks is on shopping spree. The company is reportedly considering a $400 million purchase of Israeli cybersecurity start up Koi, which raised $48 million in funding last year. 

Palo Alto told The Register it does not comment on rumor and speculation. However, a person close to Palo Alto said that this is one of several rumors that have sprouted up following a visit to Tel Aviv last month by CEO Nikesh Arora. 

"This is not the first guess coming out of the Israel media following that visit," said the person who was not authorized to make an official statement about the matter on behalf of the company. "I'm sure it won't be the last." 

During the two-day stay, Arora met with the company's 1,600 employees there as well as the teams at CyberArk, which Palo Alto is in negotiations to acquire.
