# WHATPORT(7913)

## NAME

port 7913 — qo-secure — IANA's "QuickObjects secure port" — a vendor name reservation with no public protocol.

Protocol: TCP  
IANA registry

## DESCRIPTION

7913 is registered as qo-secure, QuickObjects secure port, to an individual assignee (Jonas Bovin); 7914-7931 above it are unassigned. No specification or open implementation accompanies the registration, and Nmap sees the port open on about 0.015% of hosts. "Secure" in the registered name refers to that product's own scheme, not to any standard TLS behaviour you can rely on.

## EXPOSURE

**Expose with care.** Do not infer encryption from the name — probe the handshake and identify the service before treating the port as safe to expose.

## CHECK

```sh
openssl s_client -connect TARGET:7913 </dev/null 2>&1 | head -20
```
