- Container and orchestration APIs give full control of hosts: require mutual TLS and RBAC.
- Never expose them to the Internet.
- Rotate tokens and certificates and audit who has access.
Port 8116: Check Point Clustering
Port 8116 is assigned by IANA to cp-cluster (Check Point Clustering).
How cp-cluster works

Is port 8116 dangerous?
We have no specific security note for port 8116. Its risk depends on the program actually listening on it. General advice for devops, cloud & containers services:
IANA registry entries for port 8116
| Service | Port | Transport | Description | Reference | Updated |
|---|---|---|---|---|---|
| cp-cluster | 8116 | TCP, UDP | Check Point Clustering | - | - |
// source: IANA service name and port number registry
Which program uses port 8116, and is it reachable?
Linux
sudo ss -ltnup 'sport = :8116' # process listening on 8116
sudo lsof -nP -i :8116macOS
sudo lsof -nP -i :8116
Windows (PowerShell)
Get-NetTCPConnection -LocalPort 8116 -State Listen | Select LocalAddress, OwningProcess Get-NetUDPEndpoint -LocalPort 8116 netstat -ano | findstr :8116
From another machine
nmap -p 8116 -sV <host> sudo nmap -sU -p 8116 <host> nc -zv <host> 8116
Block it in the firewall
sudo ufw deny 8116/tcp # Linux (ufw) New-NetFirewallRule -DisplayName "Block 8116" -Direction Inbound -LocalPort 8116 -Protocol TCP -Action Block # Windows
What is port 8116 used for?
Port 8116 is assigned by IANA to cp-cluster (Check Point Clustering).
Is port 8116 TCP or UDP?
Port 8116 is registered for TCP and UDP.
Is it safe to open port 8116?
It depends on the program that listens on it. Open it only for a service you know and only to the networks that need it. Container and orchestration APIs give full control of hosts: require mutual TLS and RBAC.
How do I check if port 8116 is open?
On Linux run "ss -ltnup 'sport = :8116'", on macOS "lsof -nP -i :8116", and on Windows "netstat -ano | findstr :8116" to see the local process. From another machine, "nmap -p 8116 <host>" shows whether it is reachable.
