At a glance
What we observed in this category
Tenable Nessus, Tenable, and Rapid7 share the top three ranks in this category, each posting identical visibility scores of 37.5% and composite scores of 26.2 against a category average visibility of just 7.6%. That three-way tie at the top is notable because it means no single brand has broken away to establish a dominant AEO position. The gap between these leaders and rank-five Qualys at 25.0% is moderate, but the drop to zero-visibility brands from rank seven onward is stark.
Orca Security presents the most striking divergence between visibility and citation in this dataset. It holds zero visibility yet leads all brands on citation rate at 62.5%, placing fourth overall. This means Google AI Mode references Orca Security as a trusted source without surfacing it as a named brand answer. CyCognito shows the same pattern at a smaller scale, with 25.0% citation and zero visibility. These two brands are shaping AI answers behind the scenes without receiving direct brand mentions.
Google AI Mode is the sole engine driving all recorded performance across every brand in this dataset. The top cited sources anchor heavily on third-party and community properties, with google.com, youtube.com, reddit.com, and gartner.com appearing alongside vendor-owned domains like orca.security. That mix suggests the AI is blending analyst, community, and vendor content when constructing answers, which has direct implications for where brands should concentrate their AEO content efforts.

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 →
