Rapid7 Buys Kenzo Security to Speed AI-Driven Detection and Response

The move signals a push toward machine-speed defense in response to faster AI-enabled threats.

Overview

  • Rapid7, which announced the Kenzo Security purchase Thursday, plans to integrate the startup’s agent-based AI into its Command Platform.
  • Rapid7 says the deal shifts its managed detection and response service from AI-assisted steps to AI-run investigations that process alerts at machine speed.
  • Kenzo’s platform uses many specialized AI agents working over an entity-focused data mesh to automate alert triage, tune rules, hunt threats, and prioritize fixes.
  • Early results are company-reported, with claims of up to a 94% cut in investigation time and alert coverage rising from about 12% to full coverage.
  • Rapid7 did not disclose terms and expects no material near-term impact on revenue or profit, while flagging standard integration and execution risks.
