## What the models said about Tenable Attack Surface Management

- "The EASM component is more limited than dedicated EASM specialists, and works best alongside a dedicated EASM tool rather than instead of one" (Claude Haiku 4.5, negative prompt, soft negative)
- "the platform can be overly complex ("heavy") and expensive relative to the immediate value provided. It is often viewed as overkill" (Qwen 3.7 Flash, direct prompt, soft negative)
- "Their ASM offering is often viewed as a secondary addition to their core product" (Qwen 3.7 Flash, negative prompt, soft negative)
- "the best value pick is usually Tenable One Attack Surface Management" (GPT-5.4 mini, budget prompt, first choice)
- "Best For: Teams that prefer hard technical data and CVSS scores over abstract "risk scores," particularly for compliance-heavy industries." (Qwen 3.7 Flash, comparative prompt, alternative)
- "if you want attack surface management as part of a broader exposure management stack" (GPT-5.4 mini, direct prompt, alternative)

## 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)
