Does your MSSP or MDR provider know how to manage your signals?

### Executive summary: This blog post provides practical guidance for selecting an MSSP/MDR by outlining four critical questions to ask prospective providers: how they ingest data (the authors prefer polling for reliability and auditability), how they monitor device health and surface metrics, how they build integrations efficiently, and how they handle and communicate failures. It emphasizes verifying tooling and processes through dashboards, alerts, audits, status pages, and after-action reports to ensure the provider reliably receives signals and improves when problems occur.
