Monitor the AI tools employees use and enforce controls while they run.
Pluto emerged from stealth with a system that monitors the behavior of employee-used AI tools, including extensions and MCP servers. Its focus is the activity those tools initiate once deployed, when a static list of approved applications gives security teams limited visibility.
Pluto focuses on what employee-used agents and extensions do at runtime. Lakera Guard focuses on traffic around model calls, including malicious instructions and data extraction. The distinction matters when the immediate concern is tool execution rather than the content of a prompt.
