AI-Driven SOCCortex Xpanse
Attack surface management that finds the internet-facing risk you didn’t know you had.
Palo Alto Networks Cortex Xpanse is an attack surface management platform that continuously discovers, evaluates, and helps remediate your internet-facing attack surface — including the unknown and unmanaged assets that research shows change monthly. It gives an attacker’s-eye view of your exposed infrastructure and drives fast remediation. Faltrox operates it as the attack-surface-management layer of managed defence.
Overview
What Cortex Xpanse is
You cannot protect what you do not know you have — and Palo Alto Networks research shows that almost half of an organization’s attack surface infrastructure changes monthly, with unknown and unmanaged internet-facing assets constantly appearing. Cortex Xpanse is built to find them: it continuously discovers and monitors the internet-facing attack surface from an attacker’s perspective.
It maps your exposed infrastructure — including shadow IT, forgotten assets, and exposures you did not know existed — evaluates the risk of each, and drives fast remediation, integrating with the Cortex platform so exposures feed detection and response. That closes the gap between what you think you have exposed and what attackers can actually see and reach. Faltrox operates Xpanse — discovering the attack surface, triaging exposures, and driving remediation as managed defence.

Works with
Part of the platform
Palo Alto Networks products this pairs with, and the Faltrox services that operate it.
Delivery
You buy the outcome, not the console
Managed by Faltrox
Faltrox licenses, deploys, and tunes Palo Alto Networks Cortex Xpanse for your environment, then runs it as part of a managed service, so you get the protection without staffing another security console.
FAQ
Common questions
01What is attack surface management?
It is the continuous discovery and monitoring of your internet-facing assets from an attacker’s perspective — finding the exposed infrastructure, including unknown and unmanaged assets, that attackers can reach. You cannot protect what you do not know you have, and research shows attack surfaces change roughly monthly.
02How does it find assets we don’t know about?
It scans the internet and attributes discovered assets back to your organisation, surfacing shadow IT, forgotten systems, and exposures you did not know existed — the assets that never make it into an internal inventory but are exactly what attackers probe.
03How is it different from a vulnerability scanner?
A vulnerability scanner assesses assets you point it at; Xpanse discovers the assets themselves from the outside, including ones you did not know were exposed, and evaluates their risk. It answers "what do attackers see?" before you can scan it. The two are complementary.
04How does it fit the Cortex platform?
It integrates with Cortex Exposure Management, XSIAM, and XDR so discovered exposures feed prioritisation, detection, and response — turning attack-surface findings into action rather than a standalone report. Faltrox drives that remediation.
05How does Faltrox operate it?
We run continuous discovery of your attack surface, triage and prioritise the exposures, and drive remediation with your teams — operating attack surface management as part of the managed defence and exposure-reduction we deliver.
