# WHATPORT(3766)

## NAME

port 3766 — sitewatch-s (SSL e-watch sitewatch server) — The TLS variant of e-Watch's SiteWatch video-surveillance server port; 3765 is the cleartext one.

Protocol: TCP  
IANA registry

## DESCRIPTION

IANA registers TCP 3766 to e-Watch Corporation as sitewatch-s, the SSL form of the SiteWatch server that sits on 3765, with UDP 3766 marked Reserved; the entry was last updated in 2014. SiteWatch is a commercial video-surveillance product, and the protocol is proprietary and undocumented publicly. Outside deployments of that specific product you will not encounter this port.

## EXPOSURE

**Expose with care.** A surveillance server reachable from the internet is a camera-feed exposure risk; TLS on the transport does not substitute for putting it behind a VPN.

## CHECK

```sh
openssl s_client -connect TARGET:3766 -brief </dev/null
```
