Lasso vs Sun: AI endpoint control facts side by side

Short answer

Lasso describes 3 of the four product control types on the pages we read and Sun describes 0; they differ on browser extension, network or SSE proxy and AI or MCP gateway. On decisions, Lasso decides on a tool call before it runs and Sun 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.
