Five Browser And AI Security Questions Keeping CxOs Up At Night
Palo Alto Networks, Tuesday, March 31st, 2026
Work has fundamentally shifted from applications and networks to the browser itself. Today, the browser is where employees access SaaS, collaborate and interact with AI, making it the true operating system of modern work. But as work moved into the browser, security controls didn't follow. Within the last year, 95% of organizations have reported a security incident originating in the browser, as attackers shift their focus from hardened networks to exposed web sessions.
Legacy security tools were built for defined perimeters and managed endpoints, not for AI-powered workflows running across encrypted traffic, SaaS applications and unmanaged devices. As work increasingly happens inside the browser, many of the traditional controls that organizations have relied on simply no longer apply.
The result is a growing visibility, governance and control gap at the exact point where work happens. As AI, SaaS and browser-based workflows become the default, enterprise security leaders are forced to confront a new set of risks and questions they can no longer ignore.
