When buyers ask AI engines about Runtime application self-protection software, Contrast Security consistently emerges as the leader in responses. At the forefront with a citation visibility of 75 percent, it frequently outpaces other top brands such as Imperva and Guardsquare. This ranking underscores Contrast Security's prominence in the competitive landscape of application security tools.
The rankings are shaped by the sources referenced by AI engines, including preemptive.com, reddit.com, and contrastsecurity.com. These sources comprise both professional cybersecurity sites and community-driven platforms, offering a blend of expert analyses and user experiences. For buyers, this means that aggregated reviews and peer discussions heavily influence the AI-provided insights.

As AI engines value these facets, choosing a brand with strong, recent endorsements could provide an edge in effective application protection.
At a glance
What we observed in this category
Contrast Security holds the top composite score of 22.5, built almost entirely on a 75% citation rate despite zero visibility percentage. That gap between citation and visibility is the defining feature of this category: the number-one brand is never named unprompted but is trusted as a source when AI does respond. Imperva is the only brand with any meaningful visibility at 12.5%, making it the sole player the AI surfaces by name without being prompted by a direct brand query.
Across the top five, four brands show 0% visibility while still accumulating citation percentages ranging from 12.5% to 75%. This pattern means AI Mode is pulling these brands into answers as reference sources rather than as named recommendations. Guardsquare at rank three illustrates this clearly: a 25% citation rate with zero visibility suggests the AI treats its content as background evidence rather than a foreground answer. The category average visibility of 0.6% confirms this visibility divergence is structural, not an outlier.
Google AI Mode is the top engine for all 20 brands in this dataset, indicating the entire category's AI footprint is concentrated in one engine. Among the top cited sources, preemptive.com and reddit.com appear before contrastsecurity.com, suggesting AI anchors on third-party and community content ahead of vendor-owned domains. Sources like appsecsanta.com, hud.io, and doverunner.com also feature, pointing to niche review and aggregator sites as disproportionately influential in shaping AI responses for this category.

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 →
