## Use DLP Assist for M365

Feb 25, 2025

[Email security](https://developers.cloudflare.com/cloudflare-one/email-security/)

Cloudflare Email security customers who have Microsoft 365 environments can quickly deploy an Email DLP (Data Loss Prevention) solution for free.

Simply deploy our add-in, create a DLP policy in Cloudflare, and configure Outlook to trigger behaviors like displaying a banner, alerting end users before sending, or preventing delivery entirely.

Refer to [Outbound Data Loss Prevention](https://developers.cloudflare.com/cloudflare-one/email-security/outbound-dlp/) to learn more about this feature.

In GUI alert:

Alert before sending:

Prevent delivery:

This feature is available across these Email security packages:

* **Enterprise**
* **Enterprise + PhishGuard**
