AEO Audit is a free tool that scores B2B SaaS websites for AI search visibility — how likely they are to be cited by ChatGPT, Perplexity, and Google AI Overviews when B2B buyers search.

What is AI Engine Optimization (AEO)?

AI Engine Optimization (AEO) is the practice of structuring content, entity signals, and technical infrastructure so that AI engines cite your brand in generated answers. It extends traditional SEO to cover ChatGPT, Perplexity, Gemini, and Google AI Overviews.

FAQ

Security questions, answered

Which security vendors do AI models cite most often?+

1password and Sentinelone tie at 74, the highest scores in the category. CrowdStrike Falcon Cloud Security, Drata, IBM Business Automation Workflow, and Snyk follow at 72. No single vendor dominates shortlists — the 0% coverage rate means citations are spread thin across 69 brands.

What is the best endpoint protection software according to AI?+

Sentinelone scores 74 and rose 28 points in the last audit window, the strongest gain in the category. CrowdStrike (via Falcon Cloud Security) and traditional players like Qualys (44) and Tenable (44) trail by wide margins in AI citations.

How do email security platforms perform in AI recommendations?+

Proofpoint Enterprise DLP scores 58 in head-to-head evaluations, the highest in the category. Mimecast follows at 55, and Abnormal AI — a newer entrant — matches Beyondtrust at 50. Email security earns dedicated subcategory attention in AI training corpora.

Which identity and access management tools do AI models prefer?+

Okta scores 71, placing it among the top-cited security brands overall. Beyondtrust and Cyberark (71) also appear in evaluation queries. Sailpoint dropped 9 points recently, the largest decline in the category, suggesting shifting model preferences.

Are cloud security platforms well-represented in AI citations?+

CrowdStrike Falcon Cloud Security (72), Lacework (49 in evaluations), and Snyk (72, often cited for container/code security) form the cloud-native tier. The 65-point average score across 30 April prompts suggests cloud security keywords trigger consistent vendor mentions.

Is the security category consolidating around a few vendors in AI models?+

No. Zero vendors achieve dominant shortlist presence across 34 prompts, and the 0% coverage rate confirms extreme fragmentation. Even top scorers like 1password and Sentinelone at 74 do not monopolize citations — AI models recommend different subsets depending on query phrasing.
