AI engines like ChatGPT and Google AI identify Island as a leader in the Browser isolation platforms category, often featuring it prominently in responses to buyer inquiries. Other notable brands include Palo Alto Networks and Perception Point. While Island's visibility is not quantitatively leading, its citation rate of 12.5 percent underscores its prominence in the space.
The prevalent AI-generated rankings are shaped largely by sources such as google.com, gartner.com, and peerspot.com. These domains, some of which are aggregator or review sites, play a crucial role in influencing the AI's search results. Such sources impact how these platforms are presented, emphasizing factors like expert reviews and consumer sentiment.
For buyers exploring this page, considering what AI engines prioritize is key. Engines value recent reviews and reputable third-party validation, highlighting the importance of brands' topical authority in browser isolation. Evaluating which brands maintain a strong presence in highly cited sources can be instrumental in making an informed decision.
At a glance
What we observed in this category
Island and Palo Alto Networks share the top two positions with identical composite scores of 3.8 and matching citation rates of 12.5%, while every other brand in the top 10 sits at a composite score of 0.0. That gap is not marginal: ranks 3 through 10, including well-known names like Cisco Umbrella, Cloudflare, and Zscaler, register zero citation and zero visibility. In a category where the average citation rate is just 1.2%, only two brands are pulling any meaningful AEO weight at all.
A sharp divergence between being named and being trusted as a source is visible across the data. Cloudflare, Menlo Security, and Zscaler were previously cited at rates of 62.5%, 50%, and 37.5% respectively, but all three have dropped to 0% citation in the current audit period despite retaining ranked positions. This means Google AI Mode is still aware of these brands in context, but has stopped anchoring answers to their content, a critical AEO distinction between passive mention and active citation authority.
Google AI Mode is the sole engine recorded across all 20 brands in this audit, confirming the entire category's AEO performance lives or dies on a single channel. The top cited external sources are gartner.com, g2.com, and peerspot.com alongside google.com itself, with niche aggregators like pandastack.ai and devopsschool.com also appearing. This source mix suggests Google AI Mode is drawing on analyst and peer-review platforms rather than vendor-owned content when constructing answers about browser isolation platforms.

How to read this AEO ranking
Four things worth knowing before you act on the numbers above. These are the same definitions across every industry page — for category-specific observations, see the What we observed section above (where available) and the per-brand insights inline in the ranking.
Visibility = being named
A brand's visibility % is the share of AI answers that mention it by name in the response prose. This is who AI engines actively recommend to the buyer. More on visibility →
Citation rate = being trusted
Citation rate is the share of AI answers that include the brand's domain as a clickable source link. This is what the AI treats as authoritative evidence, different from being named. More on citation rate →
Top engine differs by brand
The "top engine" column shows which AI surface each brand performs best on. Big gaps between a brand's score across engines usually points to specific content or schema gaps. How AI engines pick sources →
AEO rankings move month to month
AI engines re-crawl and re-rank on shorter cycles than classical search. We re-audit every brand on this list at least every 90 days and refresh this page automatically. How AI search ranking works →
