At a glance
What we observed in this category
Zscaler and Twingate share the top position with identical visibility scores of 50.0% and composite scores of 42.5, placing them far above the category average of 7.5% visibility. The next closest brand, Prisma Access, sits at 25.0% visibility, meaning the two leaders collectively command attention at twice the rate of the third-ranked competitor. This gap is significant because any buyer query in this category is disproportionately likely to surface only those two brands as named options.
Prisma Access and Cloudflare One show a pattern where citation rate substantially outpaces visibility, with Prisma Access cited 62.5% of the time despite only 12.5% visibility, and Cloudflare One cited 50.0% against 12.5% visibility. Zscaler and Twingate show the inverse, with 50.0% visibility but only 25.0% citation each. This divergence indicates those two leaders are named frequently in AI responses but their source domains are not being pulled as references, while Prisma Access and Cloudflare One are trusted sources even when not prominently named.
All top 10 brands record Google AI Mode as their top engine, confirming this category's AI visibility is concentrated entirely within that single platform. Among the top cited external sources, youtube.com and peerspot.com appear alongside twingate.com and paloaltonetworks.com as direct brand domains, suggesting the AI anchors on peer review platforms, video content, and brand-owned documentation. Reddit.com also appears in the top cited sources, indicating community discussion threads are feeding into AI-generated responses for this category.

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 →
