The short version

  • Each has a real cost: IBM QRadar iBM sold the QRadar SaaS business to Palo Alto Networks in 2024 and those customers are being moved to Cortex XSIAM, so anyone buying today is choosing an on-premises product whose vendor has publicly moved the cloud future to a competitor, and the support horizon becomes a contract negotiation rather than an assumption.; VMware Carbon Black broadcom's enterprise model concentrates direct sales and support on its largest accounts and moves everyone else to resellers, so a mid-size customer can lose named support contacts and face a substantially repriced renewal with limited notice.
  • They diverge on capability: IBM QRadar covers Offence model, VMware Carbon Black covers Endpoint Standard.
  • Prices and features above were last checked on 30 August 2026.

What people use each for

The jobs each tool is most often brought in to do.

IBM QRadar

  • A regulated enterprise that must keep log data on premises or in a specific jurisdiction and cannot use a shared SaaS SIEMnot VMware Carbon Black
  • A SOC that wants log correlation and network flow analysis in one platform rather than buying an NDR product separatelynot VMware Carbon Black
  • An existing QRadar estate deciding whether to stay on premises or accept the migration path to a different vendor's platformnot VMware Carbon Black

VMware Carbon Black

  • A SOC that wants unfiltered endpoint telemetry to hunt over rather than only vendor-generated alertsnot IBM QRadar
  • A vSphere estate that wants workload protection deployed through the hypervisor instead of installing an agent in every guestnot IBM QRadar
  • Replacing signature antivirus after an incident where the incumbent product had no record of what the attacker didnot IBM QRadar
  • An organisation already inside a Broadcom or Symantec enterprise agreement that can consolidate endpoint onto an existing contractnot IBM QRadar

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

IBM QRadar

  • IBM sold the QRadar SaaS business to Palo Alto Networks in 2024 and those customers are being moved to Cortex XSIAM, so anyone buying today is choosing an on-premises product whose vendor has publicly moved the cloud future to a competitor, and the support horizon becomes a contract negotiation rather than an assumption.
  • Licensing is by events per second and flows per minute, so every additional log source raises the cost directly and teams routinely exclude verbose sources such as DNS, proxy, endpoint and cloud audit logs to stay under the licence, which strips out exactly the data an investigation later needs.
  • It needs a dedicated operator: rule tuning, parser work and offence triage are continuous jobs, and an organisation that deploys QRadar without at least one named engineer accumulates thousands of unreviewed offences and a false sense of coverage.
  • A log source without a matching Device Support Module arrives unparsed, and writing a custom parser with regular expressions against an unfamiliar payload format is specialist work that can take days per source, which quietly determines which systems ever get monitored.
  • On-premises capacity is planned across consoles, processors, collectors and data nodes, so outgrowing the sizing means procuring and racking more appliances rather than changing a subscription tier, and growth becomes a purchasing cycle measured in months.

VMware Carbon Black

  • Broadcom's enterprise model concentrates direct sales and support on its largest accounts and moves everyone else to resellers, so a mid-size customer can lose named support contacts and face a substantially repriced renewal with limited notice.
  • Continuous EDR recording is retained for a defined window and longer retention is a paid tier, so the investigation you most need is often the one whose telemetry has already aged out, and that is discovered during the incident rather than before it.
  • The product assumes an operator: watchlists, policy tuning and alert triage are ongoing work, and organisations without a dedicated analyst or an MDR contract typically leave policies in monitor mode and pay for telemetry that is never reviewed.
  • The sensor operates in the same kernel and file-filter territory as other endpoint agents, so running it alongside an incumbent antivirus, DLP or backup agent commonly produces performance complaints and requires maintained exclusion lists on both sides.
  • Linux sensor support is tied to specific distribution and kernel versions, so a routine operating system upgrade can leave hosts without a supported sensor until a matching build ships, and anything outside the supported list gets no coverage at all.

Answered from the vendors’ own pages

IBM QRadar: Who owns QRadar now?

It is split. IBM sold the QRadar SaaS assets to Palo Alto Networks in a deal announced in May 2024 and closed that September, and those customers are being migrated to Cortex XSIAM. IBM retains and supports the on-premises product.

VMware Carbon Black: Who owns Carbon Black now?

Broadcom. It acquired VMware in November 2023, and Carbon Black now sits in Broadcom's enterprise security business alongside Symantec. VMware branding is being phased out.

IBM QRadar: Is QRadar being discontinued?

IBM has committed to continuing support for on-premises customers, including security updates, while offering migration assistance. The cloud product's future belongs to Palo Alto. If you are signing a multi-year term, get the support horizon written into the contract.

VMware Carbon Black: Why do the docs use names I do not recognise?

The product has been renamed repeatedly. CB Defense is now Endpoint Standard, CB ThreatHunter is Enterprise EDR and CB LiveOps is Audit and Remediation. Older community answers and runbooks still use the previous names.

IBM QRadar: How is it licensed?

By events per second for logs and flows per minute for network data, with the software or appliance sized to that rate. Add-on modules in the suite are licensed separately.

VMware Carbon Black: Does it replace my existing antivirus?

Yes on supported Windows, macOS and Linux versions, and running it alongside another antivirus is not recommended because the two agents contend for the same hooks. Check your compliance requirements, as some auditors still ask for a named antivirus product.

IBM QRadar: What is an offence?

QRadar's term for a correlated case. Rules group related events and flows against a common indicator such as a host or user, so an analyst reviews one offence rather than the hundreds of events behind it.

VMware Carbon Black: Do I need a full-time analyst to run it?

To get value from Enterprise EDR, effectively yes. The prevention tier can run with part-time attention, but the hunting and recording capability is only worth its cost if somebody is querying it, which is why many customers buy it through an MDR provider.

IBM QRadar: Do I need a full-time engineer?

In practice yes for anything beyond a small deployment. Parser development, rule tuning and offence triage do not stop, and the most common failure mode is a well-installed QRadar that nobody has tuned since go-live.

VMware Carbon Black: How is it licensed?

Per endpoint, per year, with the capability tier determining the rate and workload and container protection priced separately. Extended EDR data retention is an additional line item.
