## What the models said about Microsoft Defender External Attack Surface Management

- "Microsoft’s native ASM is described as tightly integrated with Defender and Azure, so it may be less suitable if you need broad multi-cloud, SaaS, or heterogeneous coverage" (Perplexity Sonar, negative prompt, soft negative)
- "integrates deeply with Microsoft/Sentinel/Defender; limited third-party integration for non-Microsoft environments." (DeepSeek V4 Flash, negative prompt, soft negative)
- "while Microsoft Defender EASM is excellent at passive discovery, its active vulnerability scanning can be lacking" (Gemini 3.5 Flash, negative prompt, soft negative)
- "the best attack surface management (ASM) platform is Microsoft Defender External Attack Surface Management (EASM) if you already use Microsoft 365/E5" (GLM 4.7 FlashX, budget prompt, first choice)
- "I'd generally recommend Microsoft Defender External Attack Surface Management as the first tool to evaluate" (GPT-5.4 mini, paraphrase prompt, first choice)
- "I'd start with Microsoft Defender EASM—especially if you already use Azure or Microsoft security tools." (GPT-6 Luna, direct prompt, first choice)

## What the models said about CyCognito

- "Also flagged as a criticized challenger (39% negative labels)" (Mistral Small, negative prompt, hard negative)
- "Strong for automated discovery, but the search results point more toward complex environments than a typical mid-market default." (Perplexity Sonar, direct prompt, soft negative)
- "you do not need to pay for five-figure, enterprise-grade platforms like Palo Alto Cortex Xpanse or CyCognito" (Gemini 3.5 Flash, budget prompt, soft negative)
- "Validation separates the best. Platforms like CyCognito and Synack actively test whether exposures are truly exploitable" (DeepSeek V4 Flash, comparative prompt, first choice)
- "I'd suggest starting evaluations with CyCognito (if you want comprehensive discovery and have the budget)" (MiniMax M2.5, direct prompt, first choice)
- "Highly praised for autonomous discovery... Leaders like CyCognito stand out for validation beyond detection" (Grok 4.1 Fast, comparative prompt, first choice)
