Scan common TCP ports on any host to find open services, detect exposed endpoints, and identify potential security gaps in your network perimeter.
Port scanning checks which TCP ports on a host are open, closed, or filtered. Open ports indicate running services that may have vulnerabilities or misconfigurations. It is a fundamental step in both offensive security assessments and defensive perimeter hardening.
Every open port is a potential entry point. Unnecessary services expose attack surface. Regular scanning helps you maintain a minimal, secure perimeter.
Leaving default ports open, running outdated services, no firewall rules, and scanning external targets without authorization are common pitfalls.
Type a hostname or IP address to scan.
We attempt connections to common service ports.
Ports are marked as open, closed, or filtered.
Close unnecessary ports and restrict access with firewalls.
Scan both hostnames and raw IP addresses. Useful for checking cloud instances, load balancers, and CDN edge nodes.
Maps common ports to known services. Quickly identify SSH, HTTP, HTTPS, SMTP, FTP, MySQL, and RDP endpoints.
Classifies each port state accurately. Open means a service is listening. Filtered means a firewall or NAT may be blocking.
Quickly audit your network perimeter for exposed services. Ideal for pre-deployment checks and periodic security reviews.
Uses lightweight TCP handshakes for speed. Results arrive in seconds, not minutes. No heavy network traffic generated.
Clear summary of open vs closed vs filtered ports. Actionable security snapshot at a glance.
Automate port scans, track open port changes over time, and correlate findings with vulnerability data across your entire infrastructure.
