The Three-Class Solution: Why Bot Detection Needs to Authenticate AI Agents

As AI agents become critical infrastructure for commerce and integrations, distinguishing them from malicious bots through behavioral analysis has become impossible—modern LLM agents trivially mimic human input patterns.

This shift from behavior-based detection to identity-based verification is essential for companies that want to enable AI agents while maintaining security.
