IANA-registered to Tripwire, the file-integrity monitoring vendor.
IANA assigns 1169 to tripwire on TCP and UDP, registered by Tripwire. The original Open Source Tripwire is a local file-integrity checker that compares the filesystem against a signed baseline and opens no network listener at all, so the registration relates to the company's commercial agent/console products rather than the open-source tool. Nmap's frequency data shows it is rarely found open.
Expose with care
A security-agent control channel is a high-value target — keep it on the management network and confirm which product actually owns the listener.
