Is Lasso or Zscaler better for AI endpoint control?

Neither is scored on this site. Lasso describes 3 of four product control types and Zscaler 1 on the pages we read, and they differ on 11 recorded facts. Which fits depends on the AI tools people use, your devices, where the work happens and whether you block or guide; the finder checks those.

Which of the two decides on a tool call before it runs?

Lasso: Matches. Zscaler: Not in our sources. Warn or ask: Lasso Partly, Zscaler Not in our sources.

Do Lasso or Zscaler publish prices?

Lasso: Marketplace list price: Lasso for Employees, annual commit for GenAI chatbots, $20,000 for 12 months on AWS Marketplace. Other products: not published. Zscaler: Not published (demo request).

Lasso vs Zscaler: AI endpoint control facts side by side

Short answer

Lasso describes 3 of the four product control types on the pages we read and Zscaler describes 1; they differ on on-device control, browser extension and AI or MCP gateway. On decisions, Lasso decides on a tool call before it runs and Zscaler does not describe tool-call decisions on the pages we read. We do not score either; the right choice depends on the AI tools people use, your devices, your current stack and whether you block or guide.
