Employee negligence driven by shadow AI<\/a> cost organizations more than any other type of insider risk last year, accounting for 53% of the $19.5m lost on average per business, according to DTEX.<\/p>\n

The security vendor’s Cost of Insider Risks 2026 <\/em>report was produced by the Ponemon Institute and based on interviews with 8750 IT and security practitioners in 354 global organizations.<\/p>\n

Malicious incidents such as sabotage, data theft, fraud and unauthorized disclosure accounted for 27% ($4.7m) of the total lost to insider risks last year, DTEX claimed.<\/p>\n

That pales in comparison to negligence (e.g. ignoring IT warnings) and mistakes (e.g. accidentally “pressing the wrong button”), which amounted to an average of $10.3m in losses per company.<\/p>\n

A third category of “outsmarted” employees refers to those that may have been phished. This accounted for the smallest share of losses: 20% or $4.5m.<\/p>\n

In total, the report catalogued 7490 incidents and recorded a 20% increase in insider-related losses since 2023.<\/p>\n

Costs related to employee negligence have risen 17% year-on-year, the report found. The main causes were the use of personal webmail, file sharing sites and shadow AI.<\/p>\n

Although 73% of respondents are worried that undocumented AI use is creating invisible data loss pathways, just 13% have formally adopted AI technology into their business strategy. Only 18% have fully integrated AI governance policies into their insider risk management program.<\/p>\n
