Short answer: AI agents can look like regular users, making them hard to detect. Watch for unusual activity and use logs to find them.
TL;DR
- AI agents use different techniques to avoid detection.
- Look for unusual click timing and session behavior.
- Check OAuth consent logs for unauthorized apps.
- Monitor egress logs for unexpected API calls.
What happened?
AI agents are automated tools that mimic human behavior to avoid detection. They can follow a goal, like booking a flight, and decide their steps. To spot them, security teams look for unusual patterns in click timing, session behavior, and logs. Since these agents often look like regular users, traditional detection methods might miss them.

How it works
AI agents can look like regular users, making them hard to spot. They decide their own actions, like a human, and use browsers to click and scroll. Traditional bots follow scripts, making them easier to detect.
- AI agents use declared, undeclared or disguised traffic.
- Traditional tools miss undetected and disguised agents.
- Behave like humans, making them hard to identify.
- Look for patterns in click timing, typing, and session behavior.

FAQ
What are AI agents in cybersecurity?
AI agents are bots that work towards a goal, deciding their own steps, making them harder to detect than regular bots.
How do I find AI agents that employees set up without telling security?
Start by checking OAuth consent logs and audit logs in SaaS tools for unusual API key creations and third-party app grants.
