Is AI Access Security or Lasso better for AI endpoint control?

Neither is scored on this site. AI Access Security describes 1 of four product control types and Lasso 3 on the pages we read, and they differ on 13 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?

AI Access Security: Not in our sources. Lasso: Matches. Warn or ask: AI Access Security Not in our sources, Lasso Partly.

Do AI Access Security or Lasso publish prices?

AI Access Security: 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.

AI Access Security vs Lasso: AI endpoint control facts side by side

Short answer

AI Access Security 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 and AI or MCP gateway. On decisions, AI Access Security does not describe tool-call decisions on the pages we read 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 AI Access Security if

You already run Palo Alto Networks Prisma Access and want GenAI app controls in the same place
Your main concern is employees using many GenAI web apps rather than agents on laptops

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
