Port Scanner

Scan common ports on a target host. Attempts HTTP/S connections to detect open ports. For deeper scans, use nmap locally.

Target host

Enter a host and click Scan ports

Scan common ports on any host to identify open services. Tests 38 ports including HTTP, SSH, FTP, database, and mail.

Open port risks: Close unused ports — exposed Redis/MongoDB leads to data theft or RCE
Firewall rules: Use deny-by-default policies and whitelist specific ports/IPs → Policy Generator
Service binding: Bind databases, caches, admin panels to localhost (127.0.0.1) only
Brute-force protection: Enable fail2ban for SSH and login ports to auto-ban repeated failures
Admin port access: Use VPN/SSH tunneling for RDP/WinRM — never expose directly → Subdomain Scanner
