What is ZeroFox External Attack Surface Management?

Digital transformation, hybrid work, and complex software supply chains have all led to an unprecedented expansion of unknown and unmanaged cyber assets, systems, and exposures across the external attack surface. With ZeroFox Attack Surface Management, proactively remove threat actors’ targets of opportunity through full-spectrum discovery and enumeration of internet-facing assets, including subdomains, IP addresses, software, security certificates, Shadow IT, and more. Performing continuous correlation and analysis of exposures with actionable alerting and reporting enables the rapid prioritization of remediation decisions.

Why is ZeroFox External Attack Surface Management Important?

Last year, 83% of cyber attacks emerged outside traditional security perimeters. Traditional, often internally-focused security defenses do not detect adversaries taking advantage of exposed internet-facing assets, which is leading to increasing frequency and impact of attacks. ZeroFox Attack Surface Management protects your external attack surface by identifying subdomains, IP addresses, software, security certificates, Shadow IT, and more to streamline the correlation and investigation of exposures for your known, unknown, and unmanaged assets exposed to the internet.

Why External Attack Surface Management?

Security teams are stretched thin, constantly responding to security incidents and alerts, leaving assets exposed and ripe for attacker exploitation.


Vulnerabilities reported in 2023, up by 12% from 2022.


Firms that have been attacked through an unknown, unmanaged, or poorly managed internet-facing asset.


Median time it takes for an adversary to move laterally once compromised.
