## What the models said for it

- "Look at modern vendors built for mid-market and cloud-first environments (e.g., *Cyberhaven, Nightfall AI, Next DLP, or Code42/Incydr*)." (Gemini 3.5 Flash, DLP)
- "Cyberhaven for full‑lifecycle data lineage, or Nightfall AI for AI‑native detection with low false positives." (GLM 4.7 FlashX, Insider risk)

## And against it

- "Avoid high-end tools like Nightfall AI, IBM Guardium, or Securonix" (Grok 4.20, Insider risk)
- "Especially attractive to startups and mid-sized firms adopting cloud-first strategies, but lacks network-level DLP and deeper endpoint controls." (Claude Haiku 4.5, DLP)
- "Niche (e.g., Slack/Zendesk-focused or AI-only) and may not cover end-to-end needs." (Grok 4.20, DSPM)
