What is External Attack Surface Management (EASM)?

Forrester’s recently released definition of EASM is: “A tool or capability that scans for, discovers, and enumerates unknown internet-facing assets, establishes the unique fingerprints of discovered assets, and identifies various exposures.” In simpler terms, EASM displays your entire digital footprint, including all that you know and likely a great deal of infrastructure you did not know about.

Why do I need External Attack Surface Management?

Digital transformation, hybrid work, and complex software supply chains have all led to an unprecedented expansion of unknown and unmanaged assets, systems, and exposures across the external attack surface. EASM proactively removes threat actors’ targets of opportunity through full-spectrum discovery and enumeration of internet-facing assets, continuous correlation and analysis of exposures, and actionable alerting and reporting to rapidly prioritize mitigation and remediation decisions.

ZeroFox has been in the business of protecting external assets for over a decade, and our product team is led by several EASM visionaries. ZeroFox EASM complements ZeroFox’s industry-leading digital risk protection capabilities to deliver total visibility and control across the entire external attack surface.

ZeroFox contributes to the Amass Project, the leading open-source attack surface management platform.

What is Amass?

The Amass Project was founded in 2017 by Jeff Foley, ZeroFox’s VP of Research, to serve as an open-source tool for security practitioners getting started with EASM. It’s not a substitute for an enterprise solution, but a first foray into EASM at the practitioner level.

How to Use Amass

The Amass Project includes a collection engine for asset discovery, an asset database for storage of findings, and the Open Asset Model (contributed by ZeroFox), used by various tools to help understand attack surfaces.
