NexusNest vs Microsoft Purview
An honest, feature-by-feature comparison. Deep, native DLP for the Microsoft 365 ecosystem. Great for M365 Copilot. Significant blind spots for ChatGPT (24h lag), Claude (no integration), Cursor, GitHub Copilot, and locally-running LLMs.

|---|---|---|
Coverage of M365 Copilot | Schema-based interception when used | yes - permission-trimmed, encrypted, with sensitivity-label inheritance |

Real-time inspection | yes - every prompt, in flight | Mixed - real-time for M365 Copilot, 24h lag for ChatGPT Enterprise |
Pricing (per user/month) | ₹999–1,999/seat (~$12–24) | $33.75 (E3, basic DLP) - $54.75 (E5, with IRM) |
IRM / data-risk assessment | Not in scope | Included in E5; max 200,000 items per location for data-risk assessment |
Pick NexusNest if
Your developers use Cursor, Claude, GitHub Copilot, or any non-Microsoft AI tool. You can't wait 24 hours for ChatGPT Enterprise events. You don't want to require managed Edge / Chrome with an extension to govern browser traffic.
Pick Microsoft Purview if
Your AI usage is M365 Copilot only and you're already paying for E5. Microsoft-native sensitivity labels are critical to your compliance story.
