## New protocols added for Gateway Protocol Detection (Beta)

Feb 27, 2026 

[ Gateway ](https://developers.cloudflare.com/cloudflare-one/traffic-policies/) 

Gateway [Protocol Detection](https://developers.cloudflare.com/cloudflare-one/traffic-policies/network-policies/protocol-detection/) now supports seven additional protocols in beta:

| Protocol     | Notes                                              |
| ------------ | -------------------------------------------------- |
| IMAP         | Internet Message Access Protocol — email retrieval |
| POP3         | Post Office Protocol v3 — email retrieval          |
| SMTP         | Simple Mail Transfer Protocol — email sending      |
| MYSQL        | MySQL database wire protocol                       |
| RSYNC-DAEMON | rsync daemon protocol                              |
| LDAP         | Lightweight Directory Access Protocol              |
| NTP          | Network Time Protocol                              |

These protocols join the existing set of detected protocols (HTTP, HTTP2, SSH, TLS, DCERPC, MQTT, and TPKT) and can be used with the _Detected Protocol_ selector in [Network policies](https://developers.cloudflare.com/cloudflare-one/traffic-policies/network-policies/) to identify and filter traffic based on the application-layer protocol, without relying on port-based identification.

If protocol detection is enabled on your account, these protocols will automatically be logged when detected in your Gateway network traffic.

For more information on using Protocol Detection, refer to the [Protocol detection documentation](https://developers.cloudflare.com/cloudflare-one/traffic-policies/network-policies/protocol-detection/).
