CyberArk shares soared as much as 18% on Tuesday after The Wall Street Journal reported that cybersecurity provider Palo Alto Networks has held discussions to buy the identity management software maker for over $20 billion.

Representatives of the two companies didn’t immediately respond to requests for comment.

Cloud security is becoming an increasingly critical piece of the enterprise tech stack, especially as rapid advancements in artificial intelligence bring with them a whole new set of threats, and as ransomware attacks become more commonplace.

Founded in 2005, Palo Alto Networks has emerged in recent years as a consolidator in the cybersecurity industry and has grown into the biggest player in the space by market cap, with a valuation of over $130 billion. CEO Nikesh Arora, who was appointed to the job in 2018, has been on a spending spree, snapping up Protect AI in a deal that closed in July, and in 2023 buying Talon Cyber Security, Dig Security and Zycada Networks.

But CyberArk would represent by far Arora’s biggest bet yet. The Israeli company, which went public in 2014, provides technology that helps companies streamline the process of logging on to applications for employees.

CyberArk faces competition from Microsoft, Okta and IBM‘s HashiCorp. Another rival, SailPoint, returned to the public markets in February.

With Tuesday’s rally, CyberArk shares climbed to a record, surpassing their prior all-time high reached in February. The stock is up 29% this year, pushing the company’s market cap to almost $21 billion, after jumping 52% in 2024. Palo Alto shares, meanwhile, slid 3.5% on the report and are now up about 9% for the year.

Representatives from Palo Alto Networks and CyberArk didn’t immediately respond to requests for comment.

During the first quarter, CyberArk generated around $11.5 million in net income on around $318 million in revenue, which was up 43% from a year earlier.

It’s been an active stretch for big deals in the cyber market. Google said in March that it was spending $32 billion on Wiz, its largest acquisition on record by far, and a purchase intended to bolster its cloud business with greater AI security technology.

Networking giant Cisco also made its biggest deal ever in the security space, buying Splunk in 2023 for $28 billion. Splunk’s technology helps businesses monitor and analyze their data to minimize the risk of hacks and resolve technical issues faster.
