Movement

This is the first edition on this tier, so no move can be computed for Illumio Segmentation 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 Segmentation across every prompt where it was named for a mid-market B2B company. Fourteen models, six prompts per category.

What the models said for it

Verbatim evidence the judge attached to positive labels.

“If you want workload-centric segmentation across hybrid cloud with label-based policy and no inline appliances, Illumio is the reference.” Muse Glimmer 30B · Microsegmentation · comparative prompt · first choice
“Illumio (or Cisco Secure Workload if you're already Cisco‑shop) gives you the most granular, automated policy model.” MiniMax M2.5 · Microsegmentation · comparative prompt · first choice
“Choose Illumio if you want the clearest policy-by-label model and strong visual mapping of workload communication.” Perplexity Sonar · Microsegmentation · comparative prompt · first choice
“strongest when you want policy-based breach containment across hybrid, multi-cloud, endpoints, servers, and containers” GPT-5.4 mini · Microsegmentation · comparative prompt · first choice

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.

“host agent-based solutions (like some older versions of Illumio, Guardicore, ColorTokens, or TrueFort) can be effective, they require deploying and maintaining agents on every workload” Mistral Small · Microsegmentation · negative prompt · soft negative
“While technologies like Illumio or Guardicore use this effectively, you should be cautious if your environment has strict stability requirements” Qwen 3.7 Flash · Microsegmentation · negative prompt · soft negative
“Illumio's core enforcement still requires an agent on every workload... unmanaged OT and IoT devices only receiving monitoring, not enforcement.” Claude Haiku 4.5 · Microsegmentation · negative prompt · soft negative
“mature commercial microsegmentation tools (like Illumio or Akamai Guardicore) typically carry high enterprise minimums ($40k–$100k+)” Qwen 3.7 Flash · Microsegmentation · budget prompt · soft negative

What carried it into the answer

The sites and pages cited by the answers that named Illumio Segmentation. 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 165 of the 169 answers that named Illumio Segmentation and are not a share of its labels.

Search figures are US estimates from DataForSEO, read October 5, 2026; AI search demand is its modeled, directional estimate, not a count of queries to any assistant. The answers are this edition's. Two measurements side by side: neither is read as the cause of the other.

Events in person

Last twelve months

As the event pages on illumio.com state them, read October 5, 2026.

How it is countedHide how it is counted

Every page illumio.com exposes, subdomains included. Kind is read from the address and title. The last 90 days, the latest date and the twelve months count pages by when they were published, from the site's feeds, a date in the address, or the page's own publication date, read from up to a hundred of its most recently changed pages; a page that says only when it last changed is counted in its kind but not in when, so the recent counts are a floor, and a kind none of whose pages gives a publication date reads undated. An event counts as online when its address or title says so (webinar, on demand, virtual or online summit); a conference, summit, trade show, expo or roadshow that does not say so is counted as a conference or event, which on a vendor's site is mostly in person. Read October 5, 2026.

Is this your product?

Claim this page

Claiming is free and changes nothing in the data. A claimed page shows a verified contact who is told when each edition publishes and when Illumio Segmentation's standing changes by more than the noise floor; the right to propose corrections to the vendor table, meaning names the judge wrote that should or should not read as Illumio Segmentation, applied by version and listed in the change log; and a one-line description supplied by the vendor and marked as such.

What a new claim receivesHide what a new claim receives

A new claim receives the current edition's vendor brief for Illumio Segmentation by email, built from the raw record of the edition. It shows:

  • where Illumio Segmentation is named, by buyer and by framing, and which cells hold its first choices;
  • the claims the models make when they name it, ranked, with the strongest and the weakest quoted;
  • its vocabulary against the segment leader's, and the pages the models cited;
  • who was chosen in the answers that did not name Illumio Segmentation, and every reason the record gives;
  • a battlecard for each top rival: the head-to-head split, why they win, and the reservation quoted against them;
  • one page of published figures cleared to show a buyer.
The subscriber app

A verification link goes to your work email; an address at illumio.com is approved on the spot, any other is reviewed by hand. Your email is never published. Claiming gives no say over labels, shares, verdicts or which quotes appear.
