## What the models said about Radiant Security

- "Radiant is likely no longer a viable standalone choice for a typical mid-sized B2B stack." (Gemini 3.5 Flash, paraphrase prompt, hard negative)
- "Best for mid-market alert overload, effectively addressing the core pain point of too many alerts and not enough analysts" (Claude Haiku 4.5, direct prompt, first choice)
- "Radiant Security is praised for mid-market teams looking to reduce SIEM costs and alert noise." (Mistral Small, direct prompt, first choice)
- "Start with Dropzone AI, Prophet Security, or Radiant Security if building in-house capability" (Grok 4.1 Fast, direct prompt, first choice)

## What the models said about Microsoft Security Copilot

- "assists with queries but more copilot-like than fully agentic" (Grok 4.1 Fast, comparative prompt, soft negative)
- "Best low-budget pick: Microsoft Security Copilot—if your company already has Microsoft 365 E5 or E7." (GPT-6 Luna, budget prompt, first choice)
- "If your stack is fully Microsoft, this is the most seamless option—but it's more of a prompt-based assistant with growing autonomy" (DeepSeek V4 Flash, comparative prompt, alternative)
- "Pick Microsoft Security Copilot or CrowdStrike Charlotte AI if your SOC already standardizes on those ecosystems." (Perplexity Sonar, comparative prompt, alternative)
