Palo Alto's browser for agentic AI

Palo Alto positioned the release as an evolution of its Prisma Browser into a SASE‑native secure workspace and announced a dedicated SMB SKU, “Prisma Browser for Business,” on March 23, 2026. (prnewswire.com) The product callout lists more than 1,000 AI‑driven classifiers to flag sensitive content and enforce last‑mile data protection inside the browser. (paloaltonetworks.com) Prisma Browser also centralizes permission controls and automatically scores and blocks risky browser extensions to reduce in‑browser attack surface and data exfiltration. (paloaltonetworks.com) Palo Alto said the push follows a strategic acquisition of Koi Security on Feb. 18, 2026, which it will fold into agentic endpoint protections to govern autonomous workflows. (securityboulevard.com) The company rolled Prisma AIRS 3.0 and related updates that add discovery and risk mapping for AI agents, models and their connections across enterprise environments. (tmcnet.com) (networkworld.com) Analyst guidance has been blunt: Gartner published an advisory in December 2025 urging organizations to block AI/agentic browsers “for the foreseeable future” because of data‑exposure and rogue‑agent risks. (gartner.com) Palo Alto’s product pages explicitly reference those Gartner concerns when positioning Prisma Browser as an enterprise‑ready alternative. (paloaltonetworks.com) Palo Alto highlights adoption claims—saying Prisma is used across 97 of the Fortune 100—and cites internal telemetry that generative AI traffic surged in 2024, which it quantified in external coverage as an 890% increase year‑over‑year.
