Fumble

The Security Layer for Autonomous AI

Prevent AI before it fumbles.

LIVE AI PAYMENT

AI agents can now authorize payments, execute transactions, and move digital assets.

One compromised prompt can become a financial loss.

Fumble analyzes every action before execution.

HOW IT WORKS

A control plane between agent intent and execution.

Each request is analyzed, scoped, and validated before an autonomous system gets permission to act.

PRODUCTS

Security primitives for agent-native software.

Fumble Shield

Runtime policy enforcement for agent actions, tool calls, and high-risk execution paths.

Fumble Scan

Continuous prompt, tool, and context inspection tuned for autonomous AI workflows.

Fumble Verify

Permission checks, scoped approvals, and auditable decisions before an agent acts.

Fumble Intelligence Network

Shared threat signals for emerging jailbreaks, injections, tool abuse, and data leakage.

LIVE DEMO

Watch unsafe actions get stopped before execution.

Fumble evaluates agent behavior at runtime, returning a clear security decision before a tool call reaches production systems.

DEVELOPER FIRST

Drop Fumble into the agent path you already run.

The SDK is built for existing orchestration layers, model gateways, and internal tools. Protect an action before it leaves the trust boundary.
