# Google Cloud Platform (GCP) Callout Enforcer

The Google Cloud Platform (GCP) Callout Enforcer works with your organization's Google Cloud Load Balancers to detect and manage malicious bot activity, account takeover attempts, and other fraudulent behavior. As traffic flows through your application, these Load Balancers send callouts to the HUMAN Enforcer for analysis. When the Enforcer detects suspicious activity, it's blocked from your site and keeps malicious activity away from your web servers. This also enhances your users' experience, since the decreased web server traffic means faster load times.

Specifically, the GCP Callout Enforcer uses [Google Service Extensions](https://cloud.google.com/service-extensions/docs/overview) on your application's Load Balancer. These [traffic extensions](https://cloud.google.com/service-extensions/docs/configure-traffic-extensions) then send [callouts](https://cloud.google.com/service-extensions/docs/callouts-overview) to HUMAN's Enforcer service to block and manage bot behavior. HUMAN provides this service via [Google Private Service Connect (PSC)](https://cloud.google.com/vpc/docs/private-service-connect).
