How it reaches devicesThrough existing EDR or MDM (ephemeral binary)Browser extension, proxy, gateway, Claude Code hooks
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.Lasso offers a browser extension, proxy integrations, its MCP gateway and Claude Code hook integration, and says it works with existing stacks such as Palo Alto Networks or CrowdStrike.
