In late July, the U.S. cybersecurity giant Palo Alto Networks (PANW) announced that it had acquired the Israeli identity management and information security firm CyberArk, paying a staggering $25 billion dollars worth of cash and stock to purchase the firm.

Palo Alto is one of the world’s largest cybersecurity firms, and provides infrastructure protection, firewalls, and cloud security services to tens of thousands of companies internationally.

Udi Mokady, CyberArk’s founder and executive chairman, is an alum of Unit 8200, the Israeli Military Intelligence Directorate’s elite signals intelligence division. So are the four co-founders of Wiz: the Israeli cloud computing firm recently bought by Google for $32 billion. So, too, is Palo Alto’s Founder and Chief Technology Officer Nir Zuk.

“These acquisitions are a way to take people from Unit 8200 in Israel, and bring them into influential positions in the U.S. tech industry,” said Paul Biggar, founder of the tech startups CircleCI and Darklang and head of the activist group Tech for Palestine. “These companies handle their customers' customer data. If you are a bank, and you are using Palo Alto Networks, the data about all your customers, and their transactions, are passing through servers that are controlled by spies, or former spies.”
