Palo Alto Networks and Zscaler: GenAI security controls side by side
In short
Palo Alto Networks and Zscaler both state finds shadow AI use, inspects prompts for sensitive data, protects homegrown AI apps at runtime, blocks inline in real time and coaches or warns the user. Palo Alto Networks states covers coding agents and lists security attestations, while Zscaler states controls AI agent and MCP traffic. This page compares published facts only; it does not pick a side.

Which might suit you?
Look at Palo Alto Networks if you already run Prisma SASE and want GenAI app controls with coaching and blocking in it, or if you also want model scanning and red teaming for AI you build, from the same vendor.
Look at Zscaler if you already route user traffic through the Zero Trust Exchange and want AI app controls with coaching, or if you want MCP and agent-to-agent traffic governed at a central gateway.
