# WHATPORT(9443)

## NAME

port 9443 — HTTPS alternate (Portainer, WSO2, appliance consoles) — The default second HTTPS port — usually a management UI in a Java or container stack.

Protocol: TCP  
IANA registry

## DESCRIPTION

IANA registered 9443 to WSO2 as tungsten-https, and WSO2 products still serve their management console over it. The port became the generic "HTTPS on a non-privileged port" convention: Portainer publishes its UI on 9443, Tomcat and other Java servers commonly pair 9443 with 9080/8080, and a long list of network appliances use it for their web admin. Expect TLS and an administrative login page.

## EXPOSURE

**Expose with care.** The transport is encrypted, but what sits behind it is usually a full administrative console — often with a default certificate and, on appliances, default credentials. Restrict it to a management network.

## CHECK

```sh
curl -skI --max-time 5 https://TARGET:9443/
```
