When buyers inquire about API security testing tools, AI engines frequently mention StackHawk as the leading brand, with a visibility percentage of 25.0. 42Crunch and Burp Suite also rank highly in these discussions, but StackHawk stands out as the predominant choice, emphasizing its recognition and reliability in the field.

The rankings reflect not only brand visibility but also the sources AI engines depend on, such as stackhawk.com and appsecsanta.com. These domains, along with google.com, highlight both the presence of authoritative brand content and the influence of aggregator or review sites, which play a crucial role in shaping AI responses.

For a buyer, understanding these rankings means considering what AI engines value, like recent reviews and third-party validation. When choosing from this list, prioritize brands that demonstrate topical authority in your specific subcategory, as these are more likely to receive favorable mentions in AI-driven answers.

What we observed in this category

StackHawk holds the top composite score of 43.8, more than double the score of the three brands tied immediately below it at 17.5. That gap is not driven by visibility alone: StackHawk matches 42Crunch, Burp Suite, and Postman at 25% visibility, but its 87.5% citation rate is the decisive differentiator. In AEO terms, being named frequently is not the same as being trusted enough to cite, and StackHawk is currently the only brand in this category that demonstrates both properties together.

The visibility-citation divergence is stark across the field. 42Crunch, Burp Suite, and Postman each appear in 25% of AI responses but carry a 0% citation rate, meaning Google AI Mode mentions them without linking to them. Noname Security presents the inverse pattern at a smaller scale, with 12.5% visibility and a 25% citation rate. APIsec is the most extreme outlier: it holds zero visibility yet retains a 12.5% citation rate, suggesting residual trust signals that no longer translate into named appearances.

Google AI Mode is the dominant engine across all 18 brands in this audit, with no other engine registering as a top performer for any brand. The cited source list anchors heavily on stackhawk.com alongside third-party roundup and community sources including appsecsanta.com, community.owasp.org, testomat.io, and totalshiftleft.ai. The presence of akamai.com in that list reflects Noname Security's acquisition and domain migration, which coincides with its rise from rank 7 to rank 5 and a 12.5 percentage point visibility gain in the current period.

The AEO ranking

#	Brand	Visibility	Citation	Top engine
1	StackHawk stackhawk.com	25%	88%	Google AI Mode
StackHawk's 87.5% citation rate against a category average of 6.9% makes it the only brand converting AI visibility into consistent source-level trust in this category.
2	42Crunch 42crunch.com	25%	0%	Google AI Mode
42Crunch matches StackHawk's 25% visibility but holds a 0% citation rate, placing its composite score at 17.5 versus StackHawk's 43.8 and signalling a named-but-not-trusted AEO position.
3	Burp Suite portswigger.net	25%	0%	Google AI Mode
Burp Suite sits at 25% visibility and 0% citations, identical to 42Crunch, indicating Google AI Mode names it in responses but treats portswigger.net as a non-preferred source in this category.
4	Postman postman.com	25%	0%	Google AI Mode
Postman shares the 25% visibility, 0% citation profile of ranks 2 and 3, suggesting its AI presence in this category is broad but carries no current citation authority with Google AI Mode.
5	Noname Security akamai.com	12%	25%	Google AI Mode
Noname Security rose from rank 7 with a 12.5 point visibility gain and now shows a 25% citation rate, the second highest in the category, likely aided by its akamai.com domain appearing in cited sources.

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

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 →
