Hidden AI Tools and Browser Extensions Put Company Data at Risk

Employees are increasingly adopting web chat assistants, browser extensions, and local AI runtimes that leave no footprint in standard software lists. Because these applications operate quietly in browsers or development tools, staff can easily paste or process proprietary business information without oversight. Without direct visibility into these tools, organizations face substantial risks of unintended corporate data leakage.

Data breach security briefing

Who is affected

Any organization whose staff or developers use unapproved web-based AI tools, coding assistants, or local model runtimes on work computers.

How to mitigate it

  1. 1Audit workplace devices and browsers to discover unauthorized AI plugins, developer extensions, and local runtimes.
  2. 2Configure web filtering and endpoint controls to monitor or block unsanctioned generative AI platforms.
  3. 3Define clear corporate policies specifying which business information may be used with external artificial intelligence services.
  4. 4Implement endpoint visibility tools that detect untracked software and local AI runtime installations across the organization.

How Outsource IT solves this

Outsource IT monitors your endpoints and network traffic to identify unsanctioned AI applications and protect proprietary business data from unauthorized exposure.
