When AI engines like ChatGPT and Google AI are queried about vulnerability scanning software, Tenable is most frequently mentioned as the leader with a 25% visibility rate. Intruder and Qualys also rank high among the top brands buyers inquire about. This suggests a strong presence in the AI-driven answer space for these companies.
The rankings reflect the influence of key cited sources like YouTube, Reddit, and Tuxcare on AI engine responses. These sources mix community-driven insights with expert reviews, indicating a trend towards relying on aggregated opinions and professional evaluations to shape AI answers. Sites like Gartner further anchor these rankings with authoritative analysis.
For buyers evaluating this list, consider how AI engines emphasize current reviews and third-party validation. Look for brands with a strong topical authority and presence on platforms favored by AI engines. This can signal a robust reputation and reliable performance in the subcategory you're evaluating.
At a glance
What we observed in this category
Tenable holds rank one with 25% visibility, more than double the 12.5% shared by Qualys, Rapid7, Greenbone, and Intruder, but its composite score of 17.5 sits only marginally above Intruder's 16.2. That narrow gap at the top matters because Tenable carries a 0% citation rate while Intruder holds 25% citation, meaning a brand with half the visibility is being trusted as a source almost as often as the category leader is mentioned at all. The leadership position is fragile in AEO terms.
Visibility and citation diverge sharply across this category. Tenable, Qualys, Rapid7, and Greenbone each record 0% citations despite holding the top visibility positions, while Orca Security achieves 25% citation with 0% visibility and Wiz, Acunetix, Invicti, and Microsoft each earn 12.5% citation with no visibility at all. Google AI Mode appears to name established brands when listing options but pulls source material from different properties entirely, creating a clear split between brands that are named and brands that are trusted.
The top cited sources in this category include youtube.com, reddit.com, gartner.com, orca.security, tuxcare.com, safe.security, redcanary.com, and hostedscan.com. The presence of community and video platforms alongside analyst sources like Gartner suggests Google AI Mode is anchoring on a broad content mix rather than vendor documentation alone. Orca Security is the only brand whose own domain appears in the cited sources list, which directly explains why it achieves a 25% citation rate despite registering zero visibility in AI-generated brand mentions.

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 →

Which vulnerability scanning brands are cited rather than just mentioned?
Orca Security (25% citation), Wiz, Acunetix, Invicti, and Microsoft (each at 12.5%) earn citations, while high-visibility brands Tenable, Qualys, Rapid7, and Greenbone all record 0% citations.

Why does Orca Security rank sixth in visibility but match Intruder on citation rate?
