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

Which might suit you?
Look at Cisco if you run Cisco Secure Access and want shadow AI controls in the same console, or if agent identity and least-privilege access are your main concern.
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.

Questions
Which states more checks, Cisco or Zscaler?
Cisco states 4 of 13 checks and Zscaler states 6, on the pages we read. A count is not a quality measure: check the ones your answers make matter in the quiz.
Do Cisco and Zscaler publish prices?
Neither publishes prices on the pages we read.
Which one covers MCP and agent traffic?
Cisco: Partly stated. Secure Access registers every agent, maps it to a human owner, and quarantines compromised agents with inline runtime monitoring; MCP is not mentioned on the pages we read. Zscaler: Stated. Secures agentic communications through MCP and A2A brokers and governs agent-to-agent traffic.
