RedLegg Managed Detection and Response (MDR) is a security operations service that provides continuous threat monitoring, detection, and response capabilities. The service combines automation with human analyst review for 24x7 threat analysis and investigation. The platform offers flexible deployment options including MDR with Managed EDR for host telemetry monitoring, MDR with Managed SIEM for log and event analysis, or MDR Complete which combines both EDR and SIEM capabilities. The service is delivered on either customer-owned or RedLegg-managed platforms. Key operational components include solution management with platform deployment and configuration, detection development through a Detection Logic Lifecycle, cyber threat intelligence research, real-time threat analysis by security operations staff, automated response actions, and remediation support. The service utilizes Security Orchestration, Automation and Response (SOAR) technology to automate actions, enrich data, and reduce response times. RedLegg's Cyberfusion Center supports the MDR service with a team that includes security analysts, platform engineers, threat hunters, incident responders, and researchers. The service includes custom detection development tailored to customer environments, threat modeling, and escalation through ticketing systems. Response actions can be configured to trigger automatically based on detection playbooks to mitigate threats.
