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

Which might suit you?
Look at Netskope if MCP traffic between AI clients and remote MCP servers is your main concern, or if you need FedRAMP stated by the vendor and already run Netskope One.
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.
