Scan ports on a target host to identify open, closed, and filtered ports. Useful for network security assessment and troubleshooting.
Quick port selections:
A port scanner is a network security tool that probes a server or host for open ports. It helps identify which services are running and accessible on a target system.
Ports that are actively listening and accepting connections. These indicate running services.
Ports that are not listening for connections. The host responded but no service is running on this port.
Ports that didn't respond within the timeout period. May be blocked by a firewall or the service is slow to respond.
Port scanning is a fundamental network security technique used to discover open ports and running services on target systems. Our comprehensive port scanner tool helps cybersecurity professionals, network administrators, and penetration testers identify potential security vulnerabilities and assess network exposure.
Regular port scanning enables proactive security monitoring, helps identify unauthorized services, and ensures proper firewall configuration. Our tool provides detailed analysis of port states, service identification, and response times for comprehensive network assessment.
Input the hostname or IP address you want to scan for open ports and services.
Select ports to scan using individual ports, ranges, or common service presets.
Review detailed port status, service information, and security assessment results.
Perform comprehensive port scanning with our professional network security tool. Discover open ports, identify running services, and assess network security posture. Essential for cybersecurity professionals, network administrators, and penetration testers.
