◆ Attack Surface & Exposure Management

Palo Alto Cortex Xpanse

commercial

Summary

Palo Alto Cortex Xpanse is a commercial attack surface management platform that continuously scans the public internet to find and assess an organization's connected systems and exposed services. It runs as a service rather than something installed locally, actively discovering assets, mapping them with machine-learning models, and prioritizing remediation, which the vendor frames as closing the gap left by infrequent legacy vulnerability scanners. It is built for security teams responsible for exposure management and incident response across hybrid and cloud infrastructure, rather than for individual developers. It sits in the exposure-management category, addressing the unmanaged or unknown assets that periodic pentesting and security ratings typically miss. Palo Alto Networks launched the product in 2007, giving it a long operating history in this space.

How Palo Alto Cortex Xpanse helps

Which internet-facing systems belong to us but never showed up in our last vulnerability scan?

continuously scans the entire public internet and indexes connected systems and exposed services, catching the assets that infrequent legacy scanners miss between their scan cycles

Which of our exposed services are the highest priority to fix first?

maps the discovered attack surface with supervised machine-learning models and ranks remediation efforts, aiming to cut the time to detect and respond

Do we have unknown or unmanaged assets that an attacker could reach before we know they exist?

runs active discovery against all connected systems and exposed services and flags the ones outside current monitoring, addressing the share of assets organizations typically aren't tracking

What kinds of exposures put us at the greatest risk of lateral movement or data loss?

classifies findings into categories such as IT and networking infrastructure, business operations applications, and remote access services, the groupings that account for most high-risk exposures

How much time do we actually have between a new exposure appearing and someone finding it?

frames its continuous scanning against the gap between attacker scan speed and typical enterprise discovery time, showing where a periodic scanning approach would leave a window open
