# WHATPORT(10003)

## NAME

port 10003 — documentum_s — The secure sibling of 10002 in Documentum's IANA registration; equally rare in the wild.

Protocol: TCP/UDP  
IANA registry

## DESCRIPTION

IANA carries 10003 as documentum_s (with documentum-s as the well-formed replacement name), the secure counterpart to 10002 for the EMC Documentum Content Server product. Like 10002 it is a registration far more often cited than observed — Nmap sees it open on about 0.02% of scanned hosts. Documentum clients normally reach a repository through the connection broker on 1489.

## EXPOSURE

**Expose with care.** Content-repository ports are internal infrastructure. Confirm what is actually listening rather than relying on the registered name.

## CHECK

```sh
nmap -sV -p 10003 TARGET
```
