Block threats and gain visibility into your most targeted users
AI agents are deploying faster than ever and connecting to sensitive organizational data — almost entirely without governance. 80% of the Fortune 500 have active agents, yet only 14% have security approval.
Security teams can’t see which agents are running, who deployed them, or what data they can access.
Existing tools watch what the agent does, but ignore the human risk element.
Unsanctioned AI agents and MCP connections are expanding faster than policy can keep up.
Agentic AI Security Solution
Get visibility into AI agents in your environment. Know who deployed them. Understand what data they can reach. Act on it—before it becomes a data breach.

Is sensitive data leaving your organization?
Companies have caught source code and customer lists exfiltrated during their 30-day proof of value with Incydr.
Secure the human-agent system—not just the agent
Other vendors treat the agent as the unit of risk. Mimecast starts with a different question: who deployed it, and what do we already know about them? The risk an agent introduces is inseparable from the human directing it.
Consider two employees who deploy the same AI agent with identical permissions. The agent pulls financial records it has never touched before.
- Employee A has five years of clean history.
- Employee B has been on a watchlist for three months.
Same agent, same action — the human behind it changes everything.
Ensure Agentic AI security at scale
Mimecast automatically discovers and catalogs the full agentic landscape across every endpoint, giving security teams immediate situational awareness. Every human and agentic identity gets a risk score (0–100) and live violation feeds — no blind spots, no manual inventory.
- Agent discovery — commercial agents, endpoint AI tools, and user-built agents including shadow AI
- MCP connection mapping — GitHub, Atlassian, Slack, local file systems, and more, with full data pathway and blast radius visibility
- Sanctioning classification — every tool categorized as sanctioned, unsanctioned, or pending review in a single pane
Manage Agentic AI risk and governance
Mimecast correlates agentic activity against behavioral risk intelligence — combining endpoint, cloud, and email signals into a unified risk profile with adaptive controls.
- Acceptable use policy & sanctioning — enforce AI governance through one-click approval workflows, no ticketing queues or delays
- Human-agent correlation — every agent is linked to the human who deployed it, so risk context is never lost
- Governance scorecards — continuously assess posture across policy coverage, human-in-the-loop enforcement, and LLM compliance, mapped to frameworks including NIST AI
