59 Insider Threat Statistics You Need to Know in 2026

Insider-risk statistics for 2026 indicate that organizations face rising costs and incident volumes, with average annual losses estimated at $19.5 million and most incidents attributed to negligence, human error, or compromised accounts rather than malicious employees. Detection remains difficult because many firms lack integrated behavioral analytics, comprehensive privileged-access management, and effective access reviews, leaving administrators, contractors, executives, and former employees as notable risk categories. The report also identifies persistent credential exposure in code repositories and collaboration platforms, alongside growing use of unsanctioned generative AI tools that can expose source code and other corporate data. It argues that faster detection and containment, timely offboarding and account revocation, secret scanning, AI governance, and mature insider-risk programs can reduce both incident frequency and financial impact, while security investment in this area continues to increase.
