Attack Surface Management (ASM)

At Censys, we can see it all. Our world-leading attack surface management platform gives organizations a sixth sense — relentlessly monitoring assets, seeing the unseen, and proactively giving security teams an opportunity to solve issues before they have a chance to take place.

This isn’t security by defense. This is a system of vigilant offense that constantly looks at everything from HTTP hosts to message brokers to remote desktop exposure to network printers. Seeking potential breaches, shoring up leaks in your protocols, and mapping any potential weak points.

Discover & Investigate Internet Assets

Including, hosts, services, SaaS logins, websites, buckets, ICS/IoT devices - regardless of cloud, ac-count, network, or location for the ultimate system of record.

Conduct Rapid Response

Rapidly identify and secure Internet assets that may be exploited by a critical vulnerability.

Prioritize & Remediate Risk

Uncover, prioritize, and remediate critical risks (e.g., potential data loss, critical vulnerabilities, exposed devices/APIs/logins) within hours of coming online.

Identify Cloud Exposure

Pinpoint weaknesses in your cloud across all providers.

Manage Acquisition, Subsidiary & 3rd-Party Risk

Understand security risk associated with uncontrolled companies — acquisitions, subsidiaries, contractors, and other dependencies.
