When buyers inquire about Web application firewalls, AI engines often highlight Imperva as a leader in the field. With a visibility percentage of 62.5, it clearly stands out among its peers. Other notable mentions include Cloudflare and Akamai, suggesting a competitive landscape where these brands are frequently recognized for their capabilities.
The rankings are influenced by the sources AI engines most frequently cite. These include youtube.com, gartner.com, wafplanet.com, google.com, and reddit.com. Many of these are aggregator and review sites, reflecting a preference for platforms that provide detailed evaluations, user feedback, and expert analysis, offering a comprehensive view of brand performance.
For buyers consulting this ranking, it is crucial to consider the factors AI engines prioritize: recent reviews, third-party validation, and strong topical authority. Evaluating how a brand is discussed in these contexts can provide insights into user satisfaction and long-term reliability, aiding in a more informed decision-making process.
At a glance
What we observed in this category
Imperva leads the Web application firewalls category with a composite score of 55.0, just ahead of Cloudflare at 51.2 and Akamai at 43.8. All three share identical visibility of 62.5%, far above the category average of 13.8%, which means the top tier is clustered in name recognition but separated by citation rates. The gap between rank 3 and rank 4 (Fortinet at 25.0 composite) is substantial, suggesting a two-tier structure where the top three dominate and the rest compete for marginal presence.
Akamai's zero citation rate despite 62.5% visibility is the sharpest divergence in the dataset. It is named frequently but never cited as a source, making it a recognised brand that AI does not treat as an authoritative reference. Radware presents the inverse pattern, scoring 0.0% visibility but 37.5% citation, meaning it is cited as a source without being named as a recommended brand. This named-versus-trusted split is a defining characteristic of this category's AI visibility landscape.
Google AI Mode is the top engine for every brand in the dataset without exception, indicating that AI visibility in this category is almost entirely driven by a single engine. The top cited sources include gartner.com, youtube.com, wafplanet.com, reddit.com, and aimultiple.com, alongside radware.com itself. The presence of community and aggregator sources like reddit.com and aimultiple.com alongside analyst sources like gartner.com suggests the AI is anchoring on a mixed content diet rather than relying on vendor or analyst content alone.

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 →
