# Incident Report: Enterprise Resilience Study Findings (Endpoint Disruption)
## Executive Summary
A report by Absolute Security, surveying 750 CISOs in the US and UK, revealed significant post-breach disruption, with endpoint disruption potentially lasting up to two weeks for many organizations. Most organizations (87%) report that such incidents cost millions. Over half (55%) of respondents experienced cyber-attacks, ransomware, or data breaches in the past year that specifically took mobile, remote, or hybrid endpoint devices out of service.
