When buyers inquire about Secure access service edge platforms, AI engines consistently highlight Zscaler as the leader. With an impressive visibility percentage of 87.5, Zscaler stands out among other brands such as Fortinet and Cato Networks. This suggests a strong presence and recognition within the category, guiding potential buyers to consider Zscaler first.
The rankings are heavily influenced by citations from top sources like fortinet.com and zscaler.com, along with platforms such as YouTube, Gartner, and PeerSpot. Notably, aggregator and review sites contribute significantly to these results. This indicates that brands with a more visible and comprehensive online presence are favored by AI engines.
For buyers evaluating this landscape, one critical aspect to consider is the strength of third-party validation. AI engines value recent reviews and authoritative sources, which can serve as a reliable indicator of a brand's credibility and relevance. Choosing from this list means prioritizing brands with substantial third-party recognition and topical authority.
At a glance
What we observed in this category
Zscaler dominates the SASE AI visibility landscape with a composite score of 80.0, more than 26 points ahead of second-ranked Fortinet at 53.8. That gap matters because the category average visibility sits at just 13.8 percent, meaning most brands are functionally invisible in AI-generated responses. Zscaler's 87.5 percent visibility score is not a marginal lead but a structural dominance that compresses competitive opportunity for every other vendor in the field.
A clear divergence exists between being named and being trusted as a cited source. Prisma Access (Palo Alto Networks) holds zero visibility yet carries a 37.5 percent citation rate, appearing as a reference source without being surfaced as a recommended brand. Conversely, Cato Networks shows 50 percent visibility but only 25 percent citation, meaning AI mentions it without anchoring on its own content. Fortinet is the only top-five brand where citation rate matches or exceeds visibility, at 62.5 percent each.
Google AI Mode is the dominant engine across all 10 ranked brands, with every single brand listing it as their top engine. The top cited sources in the category include fortinet.com, zscaler.com, gartner.com, and peerspot.com, suggesting AI responses draw heavily on analyst platforms and vendor-owned content simultaneously. The presence of youtube.com and blog.openvpn.net in the citation list points to a broader and less predictable source pool than vendor SEO strategies typically target.

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 →
