Google has introduced the Security Agent, an automated service designed to enhance the security of Google Ads accounts through active monitoring. Unlike traditional methods, this tool uses AI to learn and recognize normal account behavior, enabling real-time detection of suspicious activities.
The Security Agent monitors various factors, such as email domains and user actions, to identify potential security threats. It helps address issues like security debt by monitoring login activities and suggesting adjustments to user access levels. Users are encouraged to regularly review Security Agent suggestions in their Google Ads accounts to optimize security measures.

Key features include:
- Dynamic monitoring of account activity based on historical behavior
- Flags unusual user actions to prevent unauthorized changes
- Automated security checks to reduce manual errors
