U.S.-based engineers.
Specialist Cortex Xpanse deployment, integration, optimization, and technical support from Rhenium Security’s U.S.-based engineering team.
Specialist focus
Connect external visibility to accountable action.
Discovering an exposed asset is the beginning of the work. Rhenium helps your team connect Cortex Xpanse findings to business ownership, investigation, and remediation so the information can become part of an ongoing operating process.
Discovery of internet-exposed assets and services, with context for exposure prioritization and remediation.
Official Cortex Xpanse informationWhat we help with
From the technical detail
to the working environment.
The engagement is scoped around your requirements, dependencies, and internal capabilities.
Asset context & ownership
Review discovered assets, attribution, and ownership mapping so findings reach the appropriate internal teams.
Exposure triage
Define a workflow for reviewing exposure context, setting priorities, and tracking the next technical action.
Operational integration
Connect agreed ticketing and response workflows and document the handoffs used to track remediation work.
Where engagements usually start
Find what the internet
already knows about you.
Xpanse work starts with the inventory it produces and the question every team asks next: who owns this, and does it matter?
Attack-surface baseline
Reviewing discovered assets, confirming ownership, and separating the unknown from the merely undocumented.
Policy alerts and triage
Tuning the exposure policies that generate alerts, routing them to the right owners, and deciding what gets fixed, accepted, or decommissioned.
Connecting findings to remediation
Feeding Xpanse results into ticketing, XSOAR, or the firewall team so exposures close instead of accumulating.
Acquisitions and subsidiaries
Extending discovery to newly acquired domains and ranges before they are integrated, when the risk is highest and the knowledge lowest.
Attack surface management
What the internet can see
that your inventory cannot.
Cortex Xpanse looks at your organization from the outside, the way an attacker would. The first results usually include assets no internal list accounts for.
Forgotten cloud workloads
Test servers, storage, and services started in a cloud account for a project that ended, still reachable and still billed.
Exposed remote access
RDP, SSH, VPN portals, and management interfaces reachable from the internet when they were meant to sit behind a firewall.
Certificates and domains
Expired, weak, or self-signed certificates, and domains registered by a department or an agency that nobody in IT manages.
Unsupported software
Internet-facing systems running end-of-life versions, often the first place new vulnerabilities get exploited.
Third-party hosting
Marketing sites, vendor portals, and SaaS configurations that carry your name but live on infrastructure you do not operate.
Acquired networks
IP ranges and domains that came with an acquisition and were never folded into your security standards.
From finding to fix
An exposure is only useful
once someone owns it.
Attribute
Confirm which discovered assets are yours, which belong to vendors, and which business unit owns each one.
Prioritize
Rank exposures by what is reachable, what it runs, and what it connects to, instead of working the list top to bottom.
Route
Send each exposure to its owner through ticketing or Cortex XSOAR playbooks, with the evidence attached.
Verify
Confirm from the outside that the service is closed, fixed, or formally accepted, so the same finding does not return next quarter.
The Rhenium foundation
Specialist engineering.
Business perspective.
Every Rhenium engineer is based in the United States. You work with people who can collaborate closely with your team and stay connected to the technical outcome.
A senior architect designs and reviews every engagement, and every change is delivered with a tested rollback plan and documentation your team can operate. The work is judged on the outcome in your environment, not the hours spent in it.

Questions
Cortex Xpanse questions.
What is Cortex Xpanse used for?
Cortex Xpanse is the Palo Alto Networks attack surface management platform. It discovers internet-facing assets and services that belong to your organization, including ones missing from internal inventories, and flags exposures that need attention.
How is attack surface management different from vulnerability scanning?
A vulnerability scanner checks the assets you already know about. Attack surface management works from the outside to find what you did not know you had, then identifies which of those exposures matter. The two work best together.
We already have Xpanse, but the alerts pile up. Can you help?
Yes. That is where most Xpanse engagements start. We confirm ownership, tune the policies that generate alerts, and connect them to the teams and workflows that close exposures.
Does Xpanse integrate with ticketing and Cortex XSOAR?
Yes. Findings can be routed into ticketing systems and XSOAR playbooks. We design and document those handoffs so remediation is tracked through to verification.
Is Rhenium Security a Palo Alto Networks partner?
No. Rhenium Security is an independent engineering firm. Our engineers specialize in Palo Alto Networks platforms, and we are not affiliated with, sponsored by, or endorsed by Palo Alto Networks.
