Tool guide
Understanding public port exposure
Open ports are normal for public services, but database, cache, FTP, and admin ports should be exposed only when intentionally protected.
Who it helps
- VPS and dedicated server users
- Administrators reviewing firewall rules
- Hosting customers checking service exposure
Usage instructions
Enter a public hostname or IP. Review which ports appear open and whether any sensitive services should be restricted.
Understanding the output
Open web and mail ports can be expected. Public database/cache/admin ports deserve review and should usually be firewalled to trusted IPs or VPN access.
Why it matters for hosting
Port exposure is a hosting security concern because firewall rules, control panels, and service bindings determine what the internet can reach.
