Your security stack looks fine from the dashboard and that’s the problem

**Executive summary:** The 2026 Resilience Risk Index analyzes telemetry from tens of millions of corporate endpoints and finds roughly one in five devices operate outside a reliably enforceable security state, driven by persistent control drift across vulnerability management, EPP/EDR/XDR, and SSE; rising patch ages (notably Windows 10 reaching end-of-updates), vendor consolidation risks, growing enterprise generative-AI usage, and uneven sector exposures compound downtime and data-exposure costs. The report quantifies business impact (high hourly losses and prolonged mean-time-to-recover), recommends resilience metrics (MTTR, percent remotely recoverable, downtime cost per hour, labor/IR cost), and presents case evidence that persistence-based resilience significantly reduces recovery time and annual downtime exposure.
