QRadar on-prem in 2026: your options after the QRadar SaaS sale.

What changed, and what did not

IBM sold its QRadar SaaS business to Palo Alto Networks, and Palo Alto Networks has since retired those cloud products. Its end-of-life summary lists the dates (S01):

The same page is explicit about what is out of scope: "This announcement does not affect any IBM QRadar on-premise products or SKUs" (S01). For QRadar SaaS customers, Palo Alto Networks' end-of-sale notice describes renewals limited to terms ending on or before the end-of-life date and migration services toward its Cortex products, including Cortex XSIAM (S02). Those customers have already had to move.

If you run QRadar on-prem, none of those dates applies to you. That has not stopped the market treating the sale as a reason to switch: several vendors now run "QRadar alternative" and migration campaigns. Some of that advice is useful. Some of it presents a SaaS deadline as if it were yours. The first step is to separate the two.

Where on-prem QRadar stands

On-prem QRadar SIEM stays with IBM. Three practical points follow for an on-prem team in 2026:

• Your deadline is your version's support lifecycle, not the SaaS notice. Check the end-of-support date for the QRadar version you run with IBM directly, and plan upgrades against it. We do not quote third-party lifecycle dates here, because we have not been able to confirm them against an IBM source.
• Some cloud add-ons you may have used are gone. QRadar Advisor with Watson and the X-Force Threat Intelligence product appear on the 31 August 2026 list (S01). If any of your workflows depended on them, those workflows need a replacement whatever you decide about the SIEM.
• The skills question is real. If you find it hard to hire or keep people who can run QRadar, that, rather than any vendor date, may be the real reason to move. It is a legitimate reason, and it is worth stating plainly in the decision.

The three realistic paths

Path 1. Stay on QRadar on-prem, and make it provably work

For many teams the cheapest, lowest-risk option is to stay, because the platform is paid for, the parsers are tuned and the analysts know it. Staying is only a good decision if the detections work. Use the time you would have spent on a migration to measure coverage at the four levels described in ourATT&CK coverage guide, fix silent sources and dead rules (see theSIEM health check guide), and put continuous checks in place.

Path 2. Migrate to another SIEM

The common targets are Microsoft Sentinel, Google SecOps, Splunk, Elastic and Palo Alto Networks Cortex XSIAM. Each has its own data model, query language and content library, so a migration is a detection engineering project as much as an infrastructure one. Check the target's own roadmap too: Microsoft, for example, is moving Sentinel from the Azure portal into the Defender portal, and its documentation now gives March 2027 for the Azure-portal retirement (S03). Sentinel itself continues; the change affects how your team will work in it.

Path 3. A phased move

Run QRadar and the target side by side, move log sources and use cases in waves, and switch each wave off on QRadar only when the target has shown it detects at least as much. This costs more while both systems run, but it is the only path where each step can be proven before the next one starts.

How to decide

Score each path on the same criteria, with evidence for each score:

The first two rows are the ones most often skipped. Without them, a migration can be declared a success when every log source is connected, even though half the detections that mattered never made it across.

Protect your detections either way

Whatever you choose, the detections are the asset. Rule counts do not transfer cleanly between platforms: native coverage pages typically list installed and enabled rules (S04), so a target can show more rules and still catch less. Compare like with like by measuring validated coverage on a stated denominator before and after (S05):

1. Baseline QRadar at the four levels for your prioritized techniques.
2. For each migration wave, translate the use cases, connect the sources and re-run validation on the target.
3. Switch a use case off on QRadar only when the target has reached the same level or higher.
4. Keep the evidence. It is what you show the board, the auditor and the next team to inherit the SIEM.

SOCGenX is built for this. It connects to IBM QRadar through its API, read-only by default, and to the other SIEMs listed on our integrations page. Our QRadar page explains how the same measurement runs on both sides of a migration, or keeps proving an on-prem QRadar that stays.
