## What the models said about Intruder

- "Basic scanners (e.g., some positioned as EASM like Intruder.io) discover assets but don't validate exploitability, leading to alert fatigue." (Grok 4.1 Fast, negative prompt, soft negative)
- "the strongest default pick is Intruder because multiple 2026 reviews describe it as best for medium-sized businesses and mid-market organizations" (Perplexity Sonar, direct prompt, first choice)
- "Intruder is likely the best starting point due to its transparent pricing, ease of use, and comprehensive features at a reasonable cost" (GLM 4.7 FlashX, direct prompt, first choice)

## What the models said about CrowdStrike Falcon Surface

- "note that these can be highly enterprise-focused and expensive if bought as standalone products" (Gemini 3.5 Flash, scale prompt, soft negative)
- "forcing your ASM into the Palo Alto or CrowdStrike console may create blind spots" (Qwen 3.7 Flash, negative prompt, soft negative)
- "CyCognito, CrowdStrike Falcon Surface, and Microsoft Defender EASM are strong starting points" (DeepSeek V4 Flash, scale prompt, first choice)
- "Best For: Maturity-driven programs that want to know not just what is exposed, but what is currently being attacked." (Qwen 3.7 Flash, comparative prompt, alternative)
- "If you already use Falcon for endpoint security (EDR), Falcon Surface provides a great outside-in view" (Gemini 3.5 Flash, paraphrase prompt, alternative)
