TL;DR: Copy and paste has overtaken file transfers as a leading data exfiltration path, with 77% of employees using generative AI tools to paste data and 82% doing so through unmanaged personal accounts, according to Seclore and the 2025 Browser Security Report. The security problem is now fileless leakage at the clipboard and browser layer, where traditional DLP visibility breaks down.
Editorial analysis by NHI Mgmt Group, based on content published by Seclore: “Ctrl+C and Ctrl+V are the Latest Major Data Exposure Risk”.
Key questions
Q: What breaks when copy-paste is used to move sensitive data into AI tools?
A: Copy-paste breaks file-centric monitoring because the transfer is no longer a document event, it is an interaction event.
Q: Why do unmanaged AI accounts increase data exposure risk?
A: Unmanaged AI accounts remove policy continuity between the user, the device, and the destination service.
Q: How can organisations tell whether an AI system is leaking sensitive information?
A: Look for repeated disclosure of rare phrases, unexpected references to internal documents, cross-session contamination, and outputs that mirror protected source material.
Practitioner guidance
- Define acceptable AI data-use rules Specify which classes of text, code, customer information, and internal content can be entered into AI tools, and make approved corporate AI platforms the default for sanctioned use.
- Enforce browser-level data controls Use browser security controls that can detect copy-paste activity, monitor personal sign-ins, and block risky extensions before sensitive data leaves the environment.
- Extend DLP to text and prompts Add inspection for typed text, pasted content, screenshots, and prompt payloads so policy can act on data movement that never becomes a file.
Bottom line: Copy-paste has become a practical exfiltration route because AI workflows encourage users to move sensitive text outside file-based controls.

Copy-paste has become a governance problem because the control point has moved from files to interactions. Traditional DLP was built for documents, shares, and transfers, but AI workflows fragment sensitive data into prompt-sized pieces. That means the security decision now happens at the moment of copy, paste, or prompt submission. Practitioners should treat clipboard governance as part of the identity and data control plane, not as a user-experience edge case.
A few things that frame the scale:
- Only 5.7% of organisations have full visibility into their service accounts, according to the Ultimate Guide to NHIs.
A question worth separating out:
Q: Should organisations prioritise Browser DLP before endpoint controls in GenAI-heavy environments?
A: In many GenAI-heavy environments, yes, because the browser is now the main workspace for SaaS and AI interactions. Browser DLP can stop copy, paste, uploads, downloads, and screenshots before data reaches external tools. Endpoint controls still matter, but browser enforcement often provides the fastest reduction in everyday leakage risk.
