Tcp Port Scanner

Tcp Port Scanner is the software that helps to find TCP/IP opened ports. It can scan up to 10,000 ports per second. Tcp Port Scanner scans TCP/IP ports and allows to export found opened ports to text file.

Detects open TCP ports, running services (including their versions) and does OS fingerprinting on a target IP address or hostname.

The scanner allows you to easily map the network perimeter of a company, check firewall rules and verify if your services are reachable from the Internet. Based on Nmap Online, it performs accurate port discovery and service detection.

What are Network Ports?

Network ports are the communication endpoints for a machine that is connected to the Internet. When a service listens on a port it can receive data from a client application, process it and communicate a response.

Malicious client applications (e.g. scripts, bots, malware) often exploit code found in server software that lets them get unauthorized access on the remote machine.

Port scanning is part of the first phase of a penetration test and allows you to find all network entry points available on a target system. Port scan techniques are different for TCP and UDP ports, which is why we have dedicated tools for each one.

Why should I use an Online Port Scanner?

The main benefit of using an online version of the Nmap port scanner (vs using it on your local machine) is that it gives you an external view of your systems as any malicious hacker from the Internet has. If you do the same scan from your internal network you may obtain different results because of various firewalls and network restrictions. Furthermore, our port scanner is:

  • Already configured and ready to run
  • Periodically upgraded
  • Has an easy-to-use interface over the complex command line parameters of Nmap
  • Gives you a useful report that you can share with management or stakeholdersA port scanner is a computer program that checks network ports for one of three possible statuses – open, closed, or filtered.Port scanners are valuable tools in diagnosing network and connectivity issues. However, attackers use port scanners to detect possible access points for infiltration and to identify what kinds of devices you are running on the network, like firewalls, proxy servers or VPN servers. Here, we’ll take you through the ins and outs of a port scanner, including:


Tcp Port Scanner is an application that helps you find TCP/IP open ports. Port scanner can scan network up to 10,000 ports per second. It’s really fast tcp/ip port scanner that uses SYN method of scanning. The program can save a list of open ports into a text file.

Test servers, firewalls and network perimeters with Nmap Online providing the most accurate port status of a systems Internet footprint. It is simply the easiest way to perform an external port scan.
