How it reaches devicesThrough existing EDR or MDM (ephemeral binary)Agent hooks and MCP gateway; method not published
Deployment detailBay states that it deploys through your existing EDR or MDM using Wave, an ephemeral binary that runs, scans and exits. It describes the product as agentless by design, with no new agent or tool to install, and says full deployment takes under 5 minutes (vendor-stated). Enforcement then happens locally on the device. In practice this means Bay runs beside your EDR, not in place of it.Zenity describes "lightweight monitoring, detection, and response" for local agents, using native agent hooks, OpenTelemetry and its MCP gateway. The pages we reviewed do not say whether the endpoint component installs its own agent or deploys through EDR or MDM. SaaS coverage connects to the platforms listed above.
