Slashdot reader spatwei writes: It is now more common for data to leave companies through copying and pasting than through file transfers and uploads, LayerX revealed in its Browser Security Report 2025. This shift is largely due to generative AI (genAI), with 77% of employees pasting data into AI prompts, and 32% of all copy-pastes from corporate accounts to non-corporate accounts occurring within genAI tools. 'Traditional governance built for email, file-sharing, and sanctioned SaaS didn't anticipate that copy/paste into a browser prompt would become the dominant leak vector,' LayerX CEO Or Eshed wrote in a blog post summarizing the report.

'GenAI now accounts for 11% of enterprise application usage,' notes this article from SC World, 'with adoption rising faster than many data loss protection (DLP) controls can keep up. Overall, 45% of employees actively use AI tools, with 67% of these tools being accessed via personal accounts and ChatGPT making up 92% of all use...'

'With the rise of AI-driven browsers such as OpenAI's Atlas and Perplexity's Comet, governance of AI tools' access to corporate data becomes even more urgent, the LayerX report notes.'
