Every negative label with a quote, up to three, then the highest-weighted positives, up to three. Six of eight in this category shown.
“host agent-based solutions (like some older versions of Illumio, Guardicore, ColorTokens, or TrueFort) can be effective, they require deploying and maintaining agents on every workload” Mistral Small · negative prompt · soft negative
“While technologies like Illumio or Guardicore use this effectively, you should be cautious if your environment has strict stability requirements” Qwen 3.7 Flash · negative prompt · soft negative
“Illumio's core enforcement still requires an agent on every workload... unmanaged OT and IoT devices only receiving monitoring, not enforcement.” Claude Haiku 4.5 · negative prompt · soft negative
“If you want workload-centric segmentation across hybrid cloud with label-based policy and no inline appliances, Illumio is the reference.” Muse Glimmer 30B · comparative prompt · first choice
“Illumio (or Cisco Secure Workload if you're already Cisco‑shop) gives you the most granular, automated policy model.” MiniMax M2.5 · comparative prompt · first choice
“Choose Illumio if you want the clearest policy-by-label model and strong visual mapping of workload communication.” Perplexity Sonar · comparative prompt · first choice
What the models said about VMware NSX
Every negative label with a quote, up to three, then the highest-weighted positives, up to three. Four of five in this category shown.
“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
