Where does the tradeoff appear when an MSSP focuses heavily on incident execution instead of broad cross-domain telemetry coverage?
Optiv ties incident response support to 24/7 monitoring workflows, alert triage, and escalation coordination, which can increase speed of execution when the environment aligns to its delivery layer. IBM Security emphasizes broad managed coverage across endpoint, identity, network, and application telemetry, so it reduces cross-domain blind spots when broad telemetry breadth is required. eSentire blends incident workflow execution with adversary emulation, but the breadth of coverage still depends on what telemetry is onboarded and tuned into its 24/7 operating model.
