## What the models said about Zero Networks Segment

- "Zero Networks' MFA-centric model may not suit every environment... with Kubernetes segmentation still maturing." (Claude Haiku 4.5, negative prompt, soft negative)
- "Emerging; less mature integrations" (Grok 4.1 Fast, comparative prompt, soft negative)
- "Prioritize modern, identity/label-based tools (e.g., Calico for K8s, Zero Networks for simplicity)" (Grok 4.1 Fast, negative prompt, first choice)
- "I recommend Zero Networks." (Qwen 3.7 Flash, paraphrase prompt, first choice)
- "Zero Networks (Runner-Up) - Best if: Your company is cloud-heavy or you want zero-trust segmentation" (GLM 4.7 FlashX, paraphrase prompt, alternative)

## What the models said about VMware NSX

- "Broadcom-led VMware NSX: While technically powerful, recent restructuring at Broadcom has caused confusion regarding licensing costs and support models. Be cautious of long-term contracts" (Qwen 3.7 Flash, negative prompt, soft negative)
- "If you are a VMware Shop: Stick with VMware NSX. It is native, reliable, and easiest to manage." (Qwen 3.7 Flash, comparative prompt, first choice)
- "Illumio and VMware NSX are strong contenders for hybrid environments" (Mistral Small, scale prompt, first choice)
- "If your infrastructure is 100% VMware, choose VMware NSX for seamless, low-overhead native security." (Gemini 3.5 Flash, comparative prompt, alternative)
