A new global study by cybersecurity firm Fortinet has found that while organisations are investing more heavily in data protection, data losses from insider-related security incidents are on the rise.
The 2025 Data Security Report, produced in partnership with Cybersecurity Insiders, revealed that 72% of organisations increased their budgets for insider risk and data protection last year.
However, 77% still reported at least one insider-related incident in the last 18 months, with more than half experiencing six or more such breaches.
Nearly half of the companies surveyed said these incidents cost them millions of dollars, with 41% losing between US$1 million and US$10 million and 9% suffering losses above US$10 million.
Fortinet's report attributes the rising losses to outdated data loss prevention systems that were designed for traditional, perimeter-based IT environments.
Beyond the financial impact, the report warns of serious reputational and operational risks, noting that some organisations could lose years of research or competitive advantage from a single insider-related data leak.
