What we observed in this categoryauto-generated
Tenable dominates AI visibility in the vulnerability scanning tools category with a 37.5% visibility score, more than three times the 12.5% held by both Qualys and Rapid7. Tenable Nessus, tracked separately despite sharing the tenable.com domain, adds another 25.0% visibility, meaning Tenable-branded properties collectively account for the majority of all AI-surfaced mentions. The category average sits at just 4.9% visibility across 18 brands, making the gap between leader and field unusually wide.
Qualys and Rapid7 each hold 12.5% visibility but record 0.0% citation, meaning Google AI Mode names them without anchoring to their owned content as a source. CyCognito presents the sharpest divergence in the data: 0.0% visibility paired with a 12.5% citation rate, indicating AI pulls from its content as a reference without surfacing the brand itself in responses. This named-versus-trusted split is a meaningful structural pattern across the top five ranks.
Google AI Mode is the top engine for every brand in this dataset, suggesting the audit is concentrated on that single surface. The top cited sources include youtube.com, reddit.com, gartner.com, and g2.com, pointing to AI anchoring on third-party review and community platforms rather than vendor-owned domains. Redcanary.com, pentest-tools.com, and invicti.com also appear in the cited sources list, indicating practitioner and vendor-adjacent editorial content carries weight alongside mainstream analyst references.

How to read this 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.
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.
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.
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 30 days and refresh this page automatically.
