Absolute Security: Enterprise PCs Are Left Unprotected 76 Days a Year as Endpoint Tools Fail 21% of the Time

Absolute Security's 2026 Resilience Risk Index reveals that endpoint security software fails 21% of the time, leaving enterprise PCs unprotected for up to 76 days per year. Critical OS patching lags an average of 127 days — more than double last year's figure — and 10% of enterprise PCs still run unsupported Windows 10. Protected-state integrity dropped from 64% to 55% year-over-year. The report also highlights rising risk from employees visiting generative AI sites like DeepSeek without governance controls, as browser sessions on PCs more than doubled. These gaps are estimated to contribute to $400 billion in annual downtime losses globally.
