Company Overview

Palo Alto Networks was founded in 2005 by Nir Zuk (former core architect at Check Point and co-founder of NetScreen) in Santa Clara, California. It is a global innovator and leader in cybersecurity. Drawing on his deep experience at Check Point and NetScreen, Zuk pioneered the concept of next-generation firewalls (NGFW), integrating application identification, user identity, and content inspection into traditional firewall technology, creating a new cybersecurity paradigm.

The company went public on the New York Stock Exchange in July 2012 (NYSE: PANW), and as of 2026 holds a market capitalization exceeding $100 billion with over 14,000 employees. It is one of the highest-valued pure-play cybersecurity companies globally. Palo Alto Networks' mission is to "prevent successful cyberattacks," delivering comprehensive security across network, cloud, endpoint, and AI domains.
