Decision guide
MSSP vs MDR vs SOCaaS
| MSSP | MDR | SOCaaS | |
|---|---|---|---|
| Core job | Monitor and manage security tools, logs, devices, or controls. | Detect, investigate, triage, hunt, and often contain threats. | Operate a broader outsourced SOC function across monitoring, response, tuning, and reporting. |
| After an alert | Often escalates enriched alerts to the buyer. | Investigates the alert and may take containment actions. | Owns more of the workflow from detection through response coordination. |
| Best fit | Teams needing broad managed security monitoring or device/service management. | Teams that have tools but lack 24/7 detection and response capacity. | Teams that want a provider to run much of the SOC operating model. |
| Main caution | Some MSSPs still leave investigation and response mostly with the buyer. | MDR scope varies: response can mean advice, remote containment, or incident support. | SOCaaS can be heavier, more platform-dependent, and more expensive. |
Buyer takeaways
- Do not compare labels alone; compare the exact work owned by the provider.
- Ask what happens when your team is offline.
- Pricing only makes sense after response scope and tooling assumptions are clear.
