Discover Shadow AI Before Data Is Exposed

Employees adopt AI tools long before security approves them. GuardStance uncovers every browser and desktop AI service in use, distinguishes personal accounts from corporate tenants, and stops sensitive data from leaking into unmanaged LLMs.

The AI Tool Security Never Approved

An employee uses a personal AI account to summarize internal documents. The activity may be productive, but it can also create uncertainty about where business information is being shared.

GuardStance uncovers unapproved AI tools across browsers and endpoints, shows which sensitive data is being shared, and enforces account-aware masking or blocking policies.

  • Understand Usage

    See every browser and desktop AI service in use, by user and account type.

  • Identify Data Risk

    Spot prompts and file uploads containing PII, source code, or financial data.

  • Apply Governance

    Allow corporate AI tenants, mask sensitive tokens inline, and block unapproved tools.

Which parts of GuardStance do this?

  • AI Data Security

    An inventory of AI tools, users and accounts, in the browser and on the desktop.

  • AI Firewall

    Prompts checked on the way in, answers checked on the way out.

  • Endpoint DLP

    Clipboard and uploads follow the same policy as every other exit.

Where do you start?

With visibility only: an inventory of AI use and the sensitive data involved, with no blocking turned on.
