About Red Canary

Red Canary, now part of Zscaler, sells Managed Detection & Response (MDR), a service that taps in-house experts to detect, manage, respond to, and remediate threats at scale. Managed Detection & Response (MDR) adds 24/7 human-led, AI-powered support enriched with Zscaler context.

Zscaler says the attack surface keeps expanding across networks, endpoints, identities, cloud infrastructure, and now AI applications. Zscaler says security team sizes are stagnant or shrinking, forcing SOC teams to triage more alerts, work longer hours, and accept coverage gaps.[1]

Managed Detection & Response (MDR) experts work with the Agentic SecOps platform, supported by agentic workflows and deep ZIA integration. Managed Detection & Response (MDR) enriches investigations with ZIA context and automatically enforces ZIA policies to contain threats faster.

AI agents enrich alerts with device context, user login history, and IP intelligence before triaging. AI agents filter out difficult-to-tune alerts with short natural language prompts. A 24/7 team of detection and response specialists validates threats and reduces noise. Managed Detection & Response (MDR) includes threat hunting across clouds, endpoints, and identities, with scoped findings that carry evidence and next steps.

For response, Managed Detection & Response (MDR) can automatically block URLs and IoCs via ZIA, isolate endpoints via EDR, and suspend users via the customer's IDP. Playbooks are no-code and customizable. Customers can choose team oversight to initiate specific response actions, or choose to automate. Managed Detection & Response (MDR) alerts can be sent to a SIEM, SOAR, or ITSM platform to align with existing workflows.

Zscaler MDR unifies data from AWS, GCP, Azure, and cloud security tools like Wiz to detect and stop cloud threats before impact.
