- Patch VPN gateways quickly: they are a top initial access target.
- Use certificates or MFA rather than shared secrets.
- Investigate unexpected tunnels and proxies: they are also attacker tools.

sudo lsof -nP -i :2865macOS
sudo lsof -nP -i :2865
Windows (PowerShell)

From another machine
nmap -p 2865 -sV <host> sudo nmap -sU -p 2865 <host> nc -zv <host> 2865

How do I check if port 2865 is open?
On Linux run "ss -ltnup 'sport = :2865'", on macOS "lsof -nP -i :2865", and on Windows "netstat -ano | findstr :2865" to see the local process. From another machine, "nmap -p 2865 <host>" shows whether it is reachable.
