What we observed in this categoryauto-generated
Intruder leads the attack surface management category with a composite score of 28.8, narrowly ahead of Palo Alto Networks Cortex Xpanse at 27.5. Despite this close composite gap, Intruder's visibility advantage is significant — 25.0% versus Xpanse's 12.5% — meaning it appears in AI-generated responses twice as often. Both Rapid7 and Tenable also sit at 25.0% visibility yet score only 17.5 composite, demonstrating that raw appearance frequency alone does not translate into overall AI authority in this category.
The visibility-to-citation divergence reveals two distinct brand archetypes. UpGuard holds 0.0% visibility yet a 62.5% citation rate — the highest citation figure in the dataset — meaning AI surfaces its content as a reference source without naming it as a recommended product. Xpanse mirrors this pattern with 62.5% citation against only 12.5% visibility. Conversely, Rapid7 and Tenable each hold 25.0% visibility but 0.0% citation, suggesting AI mentions them by name but does not anchor its answers in their owned content.
Google AI Mode is the dominant engine across all 20 brands in this audit, with every brand's top engine recorded as Google AI Mode. Among the top cited sources, paloaltonetworks.com and upguard.com appear first and second respectively, followed by a notable presence of reddit.com and third-party analyst sources including gartner.com and attaxion.com. This indicates Google AI Mode is drawing heavily on vendor documentation and community or analyst content rather than exclusively relying on first-party brand pages when constructing ASM category responses.

Sources AI engines trust in this category
Across the 8 buyer-intent queries we ran on attack surface management software, these are the domains Google AI Mode cited most often. If you're not on this list — or if your competitors are — that's a concrete PR / linkbuilding target.
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.
