As AI agents gain the ability to execute tools and access resources, security becomes critical. Learn how ToolGuard provides policy-based governance.

ToolGuard: Securing AI Function Calling in the Enterprise

AI agents are getting more powerful. They can now execute code, access databases, make API calls, and interact with external systems.

The Risk of Uncontrolled Tool Access

Consider an AI assistant with access to:

  • File system operations
  • Database queries
  • HTTP requests
  • Email sending

Without proper controls, a malicious prompt could:

  • Delete critical files
  • Export sensitive data
  • Send unauthorized emails
  • Access restricted systems

Enter ToolGuard

ToolGuard is SharkRouter policy-based governance layer for AI tool execution.

Key Features

  1. JSONPath Conditions - Match on any argument structure
  2. Per-User Policies - Different rules for different roles
  3. Audit Logging - Every tool call is logged
  4. Rate Limiting - Prevent abuse with per-tool limits
  5. Result Sanitization - PII redaction in tool outputs
