Every AI agent calls external tools.
The ecosystem needs a shared detection standard.

Attackers trick AI agents into leaking credentials, running malicious commands, and bypassing safety boundaries.

Without shared rules, every platform fights the same threats alone.
ATR gives the entire ecosystem a shared defense.

The Network

Every endpoint is a sensor.
Every scan strengthens the network.

Your scan results feed back into the Threat Cloud. AI analyzes new threats, crystallizes detection rules, and the community reviews them.

The more you use ATR, the safer the entire ecosystem becomes.
This is not a tool. It is a network effect.
