AI Agent Security enforces security on every AI interaction an organization runs by inspecting what goes in, controlling what comes out, and governing what agents do. AI Agent Security provides visibility into agent usage and MCP-connected systems across an environment, including agents that teams did not explicitly build or register. AI Agent Security discovers AI agents and MCP-connected tools across an environment and identifies what data, APIs, and systems agents can access. Lakera says AI Agent Security protects agents across the full lifecycle, from discovery and risk assessment to runtime enforcement.[4][8]

AI Agent Security connects cloud, low-code, and custom environments. AI Agent Security assesses each agent based on its configuration, tools, data access, MCP servers, and autonomy. AI Agent Security enforces access controls and runtime guardrails to block threats, prevent data leakage, and govern live agent actions. AI Agent Security detects and blocks prompt attacks, data leakage, unsafe tool use, and unauthorized agent actions as agents operate. Lakera says AI Agent Security blocks indirect injection through connected tools before agents act on compromised instructions. AI Agent Security requires no changes to models or prompts. AI Agent Security extends the AI Defense Plane to the agents organizations build and deploy.[4][8]
