Security operations
Cortex XSIAM implementation
and SIEM migration.
U.S.-based engineers.
Specialist Cortex XSIAM deployment, integration, optimization, and technical support from Rhenium Security’s U.S.-based engineering team.
Specialist focus
Give security operations a well-engineered foundation.
A security operations transition involves data sources, detection content, integrations, and analyst workflows. Rhenium helps structure Cortex XSIAM implementation around the capabilities your team needs and the systems already supporting your operations.
A security operations platform bringing together security data, analytics, incident management, and automation.
Official Cortex XSIAM informationWhat we help with
From the technical detail
to the working environment.
The engagement is scoped around your requirements, dependencies, and internal capabilities.
Data & migration planning
Inventory relevant data sources and existing workflows, then establish onboarding and migration priorities.
Detection & incident workflows
Engineer detection and incident-handling processes around available telemetry, operating responsibilities, and escalation needs.
Automation & team handover
Integrate agreed automations, validate their behavior, and prepare the documentation and knowledge transfer for your analysts.
Where engagements usually start
The SIEM replacement
that has to earn its keep.
XSIAM projects begin with data. Which sources come in, in what form, and how the old SIEM's content is carried over decide whether the platform delivers.
Data-source onboarding
Firewalls, endpoints, cloud, identity, and third-party feeds mapped, ingested, and parsed correctly, with ingestion volume tracked against the license.
Migrating detections from the legacy SIEM
Deciding which correlation rules, dashboards, and reports still matter, rebuilding them in XSIAM, and retiring the rest deliberately.
Automation that reduces analyst load
Playbooks for enrichment, ticketing, and first-response actions, built for the incident types your team actually sees.
Running two platforms during cutover
A parallel-run plan with validation criteria, so the old SIEM is switched off on evidence rather than on a date.
How a cutover runs
From legacy SIEM to XSIAM, in order.
Assess
Inventory data sources, ingestion volumes, existing detections, reports, and the automations analysts rely on today.
Onboard and parse
Bring sources in by priority and confirm each one parses correctly, so detections and investigations work from complete, consistent data.
Rebuild what matters
Carry over the detections, dashboards, and reports that still earn their place, and retire the rest on purpose rather than by accident.
Run in parallel, then retire
Validate coverage against agreed criteria while both platforms run, then decommission the old SIEM with nothing silently left behind.
Knowing it works
What to measure
after go-live.
A new SOC platform should be judged on evidence. These are the measures we agree on with your team before cutover, so success is defined up front rather than argued afterward.
Source coverage
Which critical sources are ingesting and parsing correctly, and which are still missing or partial.
Alert quality
How many alerts reach an analyst, and how many turn out to be real, tracked over the first months.
Automation coverage
Which incident types are enriched or handled by playbooks, and how much manual work remains for each.
Response time
How long incidents take to triage and close, compared with the baseline captured before migration.
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 XSIAM questions.
What is the difference between XSIAM and XSOAR?
XSOAR is the Palo Alto Networks security orchestration and automation platform. XSIAM is a broader security operations platform that combines data, analytics, incident management, and automation, with automation built in. We help teams decide which fits their operation.
Can we keep our current SIEM during the migration?
Yes, and we usually recommend it. Running both platforms in parallel against agreed validation criteria is the safest way to prove coverage before the old SIEM is retired.
Do we have to replace our existing endpoint tools?
Not necessarily. XSIAM can ingest data from many third-party sources. Whether to consolidate endpoint protection is a separate decision we can help you weigh.
Which detections should we migrate?
Only the ones that still matter. We review existing correlation rules, dashboards, and reports with your analysts, rebuild what earns its place, and document what is retired and why.
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.
How is XSIAM work priced?
Pricing follows scope: the number and complexity of data sources, the detections and reports carried over, the automations required, and the length of the parallel run.
