Neither is scored on this site. Koi describes 1 of four product control types and Lasso 3 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?

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

Do Koi or Lasso publish prices?

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

Koi vs Lasso: AI endpoint control facts side by side

Short answer

Koi describes 1 of the four product control types on the pages we read and Lasso describes 3; they differ on on-device control, browser extension, network or SSE proxy and AI or MCP gateway. On decisions, Koi describes some control over tool calls and Lasso decides on a tool call before it runs. 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.

Choose Koi if

You already run Palo Alto Networks Cortex XDR
You want to find and remove risky extensions and packages across the fleet

Choose Lasso if

You want controls in several places at once: browser, proxy, MCP gateway and coding agent hooks
You prefer an open-source MCP gateway you can inspect

Which limits should you check?

Koi

Agent-based: it adds an agent unless you run it as a Cortex XDR module.
Warn or ask actions and a record that separates a person from an agent are not described on the pages we read, and no pricing is published.

Lasso

Several components to deploy and run.
Asking the user before an action is not described, and the only public price covers its chatbot product on AWS Marketplace.
