# Advanced Threat Detection

With Advanced Threat Detection (ATD), FusionAuth safeguards data, enforces compliance, and protects your platform. Stay secure and earn user trust.

## Threat Detection Flagging & Response

Leverage FusionAuth's webhooks to identify anomalous user behavior such as impossible travel, duplicate registrations, or MFA removals. Automate responses based on your security policies, including account lockouts or targeted user outreach, for a robust and efficient security posture.

## Alert Your Users

Build trust through transparency by keeping your users informed of potential security risks. Send customizable, localized email alerts for high-impact activities like adding new MFA methods or updating email addresses.

## Lock Down Access

Create a fortress around your applications with customizable, IP access control lists, and CAPTCHAs. These multi-layered defenses significantly reduce the risk of automated attacks, brute-force attempts, and unauthorized access, ensuring your users' data remains protected.

## Location Aware Security

Leverage geolocation data to enhance your security measures. With ATD, FusionAuth enriches all webhooks and login records with location information, enabling you to quickly identify and respond to geographically suspicious activities, adding an extra layer of protection to user accounts.
