At a glance
What we observed in this category
Snyk leads the application security testing tools category with 50% visibility, nearly four times the category average of 10.6%. That gap is significant because the next closest brands, Veracode and GitHub Advanced Security, sit at 37.5% each, meaning Snyk holds a clear first-place position rather than sharing the top tier. However, Snyk carries a 0% citation rate, which means its dominance is entirely driven by named mentions in AI responses rather than sourced references.
The visibility-to-citation divergence is the sharpest pattern in this data. StackHawk sits at rank 2 with only 12.5% visibility but a 75% citation rate, the highest in the category. Appknox presents an even starker case, registering 0% visibility while achieving a 25% citation rate, meaning AI is actively citing it as a source without naming it as a brand in responses. GitHub Advanced Security mirrors Snyk with 37.5% visibility and 0% citations, confirming two distinct modes of AI presence in this category.
Every brand in the top 10 lists Google AI Mode as their top engine, indicating this category's AI visibility landscape is concentrated entirely within that single engine. The top cited external sources include endorlabs.com, orca.security, gartner.com, and owasp.org, none of which are primary vendors in this dataset. That pattern suggests Google AI Mode is anchoring its responses on third-party analysis and standards bodies rather than vendor-owned content, which explains why high-visibility brands like Snyk and GitHub Advanced Security carry zero citation credit.

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 →
