In this episode, Dr. Dave Chatterjee speaks with Anupam Upadhyay, Senior Vice President, Product Management, Palo Alto Networks, a seasoned product and cybersecurity leader, to unpack the “new browser wars” and why enterprise browsers are fast becoming a core battleground in the fight for digital trust. Drawing on over two decades of experience spanning Cisco, startups, and Palo Alto, Upadhyay traces the evolution of the humble browser from a passive content viewer into the primary interface for cloud applications, collaboration tools, and sensitive business data.

The conversation examines the browser’s expanding role as both a productivity hub and a primary attack vector—accounting for over 90 percent of initial intrusions via phishing, malicious extensions, or session hijacking. Through the lens of the Commitment-Preparedness-Discipline (CPD) Framework, Dr. Chatterjee and Anupam Upadhyay emphasize that securing the enterprise browser is not merely a technical exercise but a governance imperative: leadership commitment to zero-trust principles, preparedness through hardened configurations and employee training, and disciplined enforcement of consistent controls across devices and partners.
