Cortex Xpanse is an attack surface management solution that offers comprehensive visibility and monitoring of your organization's internet-facing assets, including IT infrastructure, applications, and cloud resources. Xpanse is powered by the following capabilities:

1. Active discovery: Automatically and continuously scan the entire internet. Actively discover and index your unknown risks in all connected systems and exposed services.

2. Active learning: Use supervised machine learning models to continuously map your attack surface and prioritize remediation efforts. Confirm vulnerabilities with attack surface testing. Reduce MTTD and MTTR without additional analysts. 

3. Active response: Immediately reduce your attack surface risks with built-in automated playbooks that resolve exposures or identify asset owners and business context instead of merely raising IT tickets.
