The Unseen Risk of Generative AI: Why Traditional Security Fails – Menlo Security

Generative AI has burst onto the scene, promising to help users work faster and more productively. However, this productivity comes with a significant and often unseen risk. Many employees are using personal, free-tier GenAI tools at work, which can expose sensitive company data to the public large language models (LLMs) that power these tools. In fact, nearly half of all enterprise employees report having uploaded confidential company information—such as financial data or customer details—into public AI tools.

About half (48-49%) of enterprise employees report that they have uploaded sensitive company information, such as financial, sales, or customer information, or copyrighted material, into public AI tools.1

The problem is that traditional security solutions aren't equipped to handle this modern threat.

  • Legacy Data Loss Prevention (DLP) was built to prevent outbound file exfiltration, not the unstructured, conversational data flows common in GenAI. These tools are often blind to the simple copy-and-paste actions users perform within a web browser.
  • Cloud Access Security Brokers (CASBs) also fall short. They were designed for sanctioned cloud apps and often miss GenAI traffic, which lives in web browser sessions, extensions, and personal accounts. They cannot effectively parse the unstructured content that is the backbone of these exchanges.

Since the modern workspace, and GenAI itself, lives in the browser, that's where security needs to be. For a DLP solution to be truly effective, it must function within the browser environment, providing real-time controls over copy/paste, uploads, and downloads. Menlo Security provides these precise, in-browser controls that are vital for securing the next-generation workspace without sacrificing productivity.
