## Warned against

- Illumio Segmentation: 13 of 55 labels negative. "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)
- VMware NSX: 13 of 32 labels negative. "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)
- Akamai Guardicore Segmentation: 10 of 51 labels negative. "Avoid first if budget is tight: Akamai Guardicore, because pricing can be a constraint." (GPT-5.4 mini, budget prompt)
- Cisco Secure Workload: 7 of 28 labels negative. "Frequently called out as problematic... "the worst product"... Avoid if you lack deep expertise or time for constant tweaks." (Grok 4.1 Fast, negative prompt)
