# WHATPORT(1069)

## NAME

port 1069 — Cognex In-Sight — Reserved by Cognex for In-Sight machine-vision system communications — a factory-floor port.

Protocol: TCP  
IANA registry

## DESCRIPTION

IANA registers 1069 as `cognex-insight`, "COGNEX-INSIGHT", assigned to Cognex for its In-Sight smart cameras and vision systems. Cognex's In-Sight documentation states that 1069 is reserved for In-Sight communications and therefore cannot be chosen as a custom Telnet port; the Native Mode ASCII control protocol that operators use to drive a camera over Ethernet defaults to Telnet on port 23. So 1069 is an internal reservation of the In-Sight software rather than a protocol you interact with by hand. Finding it open places the host on an industrial network running Cognex vision hardware.

## EXPOSURE

**Do not expose.** Industrial vision systems sit on OT networks with weak or absent authentication and control physical processes — segment them, and never route this to the internet.

## CHECK

```sh
nmap -Pn -sV -p 1069,23 TARGET
```
