What is ET Ducky?

ET Ducky is a remote monitoring and management platform built on kernel-level telemetry (ETW on Windows, eBPF on Linux). Every alert and detection is backed by the kernel events that caused it, and each alert gets an automatic root-cause analysis. Remote desktop, patch management with rollout rings, behavioral security rules, automations, and natural-language reports are included at every tier. A self-hosted edition (Local-First) runs on your own infrastructure.

Available on: Web, Desktop

Is ET Ducky worth the price?

Fair value

The free tier is a strong entry point for users who bring their own AI key, but the Business ($99) and Enterprise ($249) tiers offer no additional agent count beyond the 20-per-user pool, making them better suited for orgs needing higher AI query volume and support rather than agent density.

Best for budget-conscious IT teams managing fewer than 50 agents with modest AI query needs.
