Expander is Cortex Xpanse's marquee Software-as-a-Service (SaaS) web application and API that discovers, monitors, and tracks your global Internet attack surface, identifying new, existing, and unknown assets, and helping customers reduce exposure to attackers. Expander is agentless and SaaS-based, requiring zero hardware or software install to provide you with a complete, real-time view of all of your Internet-connected assets and what's talking to them.
Expander is powered by Cortex Xpanse's global Internet intelligence platform that continuously collects and correlates petabytes of active and passive information about every device and service connected to the public Internet. Using this information, Cortex Xpanse intelligently attributes assets to specific organizations, helping customers discover and protect previously unknown Internet-connected systems.
