What is Red Canary (a Zscaler company)?

Red Canary delivers managed detection and response built on detection engineering rigor and broad telemetry ingestion (Microsoft Defender, CrowdStrike, SentinelOne, Palo Alto, Zscaler, AWS, Google Cloud, 200+ tools). It is widely regarded as a reference partner for organisations standardising on Microsoft Defender for Endpoint and Sentinel. Zscaler closed the $692M acquisition on August 1, 2025; Red Canary operates as a separate business unit within Zscaler.

✗ Limited public pricing
