# WHATPORT(44443)

## NAME

port 44443 — ColdFusion Advanced Security (coldfusion-auth) — The second coldfusion-auth port in Nmap's database, and otherwise an unregistered number that reads like an alternate HTTPS.

Protocol: TCP  
IANA registry

## DESCRIPTION

44443 has no IANA assignment; Nmap names it coldfusion-auth alongside 44442, from the Allaire/Netegrity Advanced Security component of old ColdFusion releases. Because the digits echo 443, it also gets picked by hand as an alternate HTTPS port, so a TLS handshake succeeding here does not make it ColdFusion. Open frequency in Nmap's data is about 0.02%.

## EXPOSURE

**Expose with care.** Two very different things answer on this number, so identify which before deciding — a legacy ColdFusion auth service should never be reachable, while a properly configured alternate HTTPS listener is a normal thing to expose.

## CHECK

```sh
openssl s_client -connect TARGET:44443 -brief </dev/null
```
