## What the models said for it

- "For most mid-market B2B companies, Microsoft Defender for IoT (if you are a Microsoft shop) or Fortinet (if you use their network hardware) are the most successful starting points" (Gemini 3.5 Flash, OT/IoT security)
- "For a small company with one OT site and up to 100 devices, I'd start by evaluating Microsoft Defender for IoT's XS site license." (GPT-6 Luna, OT/IoT security)
- "I'd suggest starting with Microsoft Defender for IoT ($70-250/month) as the most cost-effective commercial solution" (Kimi K2, OT/IoT security)
- "Microsoft Defender for IoT (OT tier) stands out as one of the most affordable commercial OT security platforms" (Grok 4.1 Fast, OT/IoT security)

## And against it

- "Avoid if budget is tight: Nozomi Networks and Microsoft Defender for IoT" (Perplexity Sonar, OT/IoT security)

- "These are IT-security vendors extending into OT. Their effectiveness depends on how well their OT findings integrate with your existing SOC" (Mistral Small, OT/IoT security)
- "Microsoft (Sentinel on Stack) and Splunk increasingly have strong OT apps, though often requiring more assembly effort." (Qwen 3.7 Flash, OT/IoT security)
