Palo Alto Networks is in talks to acquire US-Israeli information security firm Demisto, the Calcalist financial daily reported on its website on Monday.
Palo Alto was not available for comment outside US business hours while Demisto was not immediately available for comment.
Calcalist said Demisto declined to comment but quoted co-founder Dan Sarel as saying: "The company is now experiencing significant growth in both sales and number of employees."
Demisto, founded in 2015 by four McAfee executives, develops and markets automation tools for information security management, including a chatbot that assists security analysts in handling tasks.
Last October, the company raised US$43 million in a funding round led by Greylock Partners, bringing its total equity funding to US$69 million. Accel Partners, ClearSky Security, Slack Technologies, Wipro Ventures, Secure Octane, and Cerca Partners are also backers.
