Understand what you own, what’s at risk, and how to protect your most critical assets

Expanse Expander discovers, monitors, and tracks your global Internet attack surface, identifying new, existing, and unknown assets, and helps reduce your exposure to attackers.

Expanse Behavior provides a complete, outside-in view of the behavior of your perimeter, its responsive assets, and their communication outside your organization.

Expanse Infographic

Global internet sensing platform

Expanse maintains a historical record of all assets connected to the Internet, who owns them, and communications between them.

Expanse analyzes and tracks Internet-connected assets and communications between them. Our Sensing Platform indexes the entire Internet, storing data about devices connected as well as communications observed between them. Using this data, Expanse can identify assets that have been abandoned or misconfigured, as well as those that may be compromised.

Global edge tracking engine

Dynamic Internet asset discovery and inventory.

Expanse classifies and tracks billions of IPs and trillions of associated network flows, looking for system information that can tie assets back to an organization. This complete and accurate view of their Internet-exposed assets serves as a single source of truth and better inform security operations and other tools.



Understand and monitor your global Internet attack surface

Your Internet-facing assets are constantly under attack from targeted and opportunistic attackers. Without a continuously updated, accurate inventory of those assets, you leave unknown or unmonitored assets exposed to threats. Expander discovers and helps remediate any exposures on those assets.

With Expander, security and IT operations teams have the visibility they need to reduce risk to the business by focusing remediation efforts on critical exposures and assets out of compliance with policy. Expander can automatically update your asset lists and processes, providing a single source of truth about assets that are tied to your organization, including on-premise, through partners, and in cloud providers.

Understand the communication activity between your Internet-connected assets and others

Discover communication flowing between assets on your attack surface and those outside without the burden of network traffic collection, analysis, or costly infrastructure.

Behavior intelligently identifies assets in your inventory that are making risky connections to out-of-policy services like Tor and BitTorrent, without needing to instrument any of your ingress or egress points. Behavior passively detects communications across the global Internet, allowing security teams to discover network policy gaps and check that compliance controls are implemented properly.
