Expel built its reputation on transparency: instead of a black-box service that returns verdicts, it gives you real-time visibility into what its analysts are doing, why, and what they're recommending. For a mid-market CISO who has been burned by opaque MDR and wants to see the work rather than trust it on faith, that visibility is the whole point. You own the relationship and the audit trail; Expel runs the detection and response.
Expel delivers managed detection and response with transparency as the organizing principle. Where most MDR providers hand back conclusions, Expel surfaces the analyst's working — the signals, the reasoning, the recommended remediation — in real time. It ingests across cloud, SaaS, endpoint, network, and identity, and the differentiator is less the breadth of coverage than the openness of the operation. For security leaders who need to defend their MDR choice to a board or an auditor, "we can see exactly what they did" is a strong answer.
A security leader who wants to see and audit every analyst action, not just receive verdicts. Expel's transparency is built for exactly this buyer.
If you answer to a board or auditors and need to evidence the MDR workflow, the open audit trail is a defensible, repeatable answer.
If you'd rather delegate fully and not watch the work, Arctic Wolf's named-team concierge model may suit your preference better. Worth comparing.
If your detection strategy is built around one SIEM you intend to own, a SIEM-led MDR like Rapid7 may align more naturally. Brief that instead.
