It is now more common for data to leave companies through copying and paste 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.
