This contrasts with 27% in smaller firms under $250 million. The study highlights that AI-accelerated attacks have significantly changed the cybersecurity landscape, with 91% of respondents acknowledging this shift. Many organizations face challenges in patching due to business trade-offs and operational disruptions. Additionally, 54% of security leaders reported that burnout is impacting their teams' effectiveness. The survey, conducted with 1,300 security leaders, indicates a growing concern about the speed of AI-driven exploitations outpacing remediation efforts. Companies are reallocating resources and hiring more staff to address these vulnerabilities, but a significant gap remains between vulnerability discovery and remediation.
