In an MSSP, analysts often work with multiple customers and must meet SLA requirements. They handle customer-facing communications, produce incident reports, manage multi-tenant SIEM environments, support onboarding of new log sources and use cases, and maintain high alert throughput while ensuring investigation quality.
Community discussions note that exact L1, L2, L3 responsibilities vary between MSSPs, but L1 generally focuses on triage; L2 on investigations and response; L3 on threat hunting, detection engineering, and complex escalations.
