The 2AM Test: How to Evaluate MDR When It Actually Matters

With 67% of security decision-makers reporting at least one breach in the past year and 88–91% of ransomware attacks launching outside business hours, the real test of an MDR partner isn't the dashboard: it's whether someone (or something) is authorized to act at 2AM on a Saturday. This guide contrasts alert-led MDR (detect, validate, notify) against response-led MDR (detect, investigate, contain, then inform), breaks down the four clocks that actually measure response speed (MTTA, MTTR, MTTC, MTTD), and walks through real-world incidents (Kaseya, ConnectWise ScreenConnect, Snowflake, MGM Resorts, and 3CX) where authority and pre-established scope, not detection, made the difference. It closes with a full RFP question bank and a 13-point executive checklist for scoring any current or prospective MDR provider.
