October 2026 Edition. Every number here is derived from the raw labels under vendor table v2026-10.8, every buyer segment counted.

Standing

6 labels, too few to rank

A product needs 10 labels in a category before a share or quadrant is stated. Illumio Core was named 6 times in Microsegmentation, where ColorTokens Xshield led with 25%. The labels and the evidence are below, counted exactly.

Movement

This is the first edition on this tier, so no move can be computed for Illumio Core yet. From the next edition this section shows, per buyer segment and per category, whether its share moved by more than the measured noise floor.

By model

How each model treated Illumio Core across every prompt where it was named for a mid-market B2B company. Fourteen models, six prompts per category.

By framing

Which of the six questions produced the naming. By model says how often; this says asked what. The first-choice count on the right carries the marks of the models that produced it.

What the models said for it

Verbatim evidence the judge attached to positive labels.

“Illumio and VMware NSX are strong contenders for hybrid environments” Mistral Small · Microsegmentation · scale prompt · first choice

“compare Illumio and Guardicore first” GPT-6 Luna · Microsegmentation · comparative prompt · first choice

“Illumio Core (Enterprise Leader) - Cons: Higher cost, steeper learning curve, premium pricing” GLM 4.7 FlashX · Microsegmentation · paraphrase prompt · alternative

“If you are Multi-Cloud/Bare-Metal Heavy: Consider Illumio” Qwen 3.7 Flash · Microsegmentation · comparative prompt · alternative

And against it

Verbatim evidence attached to negative labels. A warning on a product with few labels is a warning; on a product with many, it is one voice among them.

“Caution level: Moderate (market leader, but not without pitfalls)” DeepSeek V4 Flash · Microsegmentation · negative prompt · soft negative

“start at $100k+ Year 1 (60–80% implementation costs)... not SMEs” Grok 4.1 Fast · Microsegmentation · budget prompt · soft negative

What carried it into the answer

The sites and pages cited by the answers that named Illumio Core. A fact about retrieval, not a lever on the model.

Citations exist only for the models that return a source list, five of the fourteen in this edition, so these counts come from 14 of the 17 answers that named Illumio Core and are not a share of its labels.
