Advanced Network Port Scanner

About Port Scanner

Port Scanner probes your network to find open ports and the services running on them. It scans both TCP and UDP ports in your network, which act as a medium of communication between processes in your network. As a network admin, using a port scanner helps you in network reconnaissance, by giving you the list of open ports in your network, connected switches, the services running on them, and associate the known services with those running on the ports.

What is a Port Scanner Tool ?

The network port scanner tool is an important aspect of scanning and managing network ports. On a large network, monitoring and managing open ports can be extremely time-consuming. Employing an advanced port scanning software helps you to efficiently carry out this task.

End to end port scan: Find open TCP or UDP ports in your network efficiently with a port scan tool. A port scanner software can continually scan your network and update you with the status of network ports, connected switches and the services running on them.

Eliminates manual switch port mapping: Any given switch in a network is associated with a set of ports, and manually tracing and keeping note of them is a tedious process. A port scanner tool on conducting a port scan, enables the network admin to receive detailed insight into switch port mapping without having to trace the cables manually.

Why is port scanning important?

Not employing an effective port scanner software capable of advanced port scanning, opens up your network to various threats. Ports left unmonitored may lead to various attacks on your network under monitor, including data breach.

Risks of not having a network port scanning tool:

Open port vulnerabilities: Some ports might remain continually open, presenting a potential vulnerability to the network. An intruder can use this to wreak havoc in the normal flow of network operations.

Avoid data leakage: Network ports have to be closely monitored by an effective network port scanning tool in order to avoid any data leakage, and aid in securing communication between the computing processes.

Setting up an advanced port scanning tool like OpUtils can help you to virtually eliminate this risk vector.

OpUtils' advanced port scan tool

The advanced port scanner tool finds the status of ports in a network by attempting to connect to any open ports. This enables admins to check if network configurations are set up according to the organization's security policies, and remedy them if they are in violation. The advanced port scanner tool consists of features such as:

  1. Real-time switch port mapping.
  2. A comprehensive summary of network ports.
  3. Alerts and email notifications.
  4. Port scanner widgets.
  5. Administratively enabling or disabling interfaces.
  6. Port scan scheduling. 
  7. Role-based access management.

Real-time switch port mapping.

With OpUtils network port scanner tool, a network admin can scan ports in real time by manually adding switches, importing from a CSV file, or by discovering all the switches in the given IP range by performing a network port scan. Once the switches have been added, the advanced port scanner tool displays all the ports that are associated with the corresponding switches.

A comprehensive summary of network ports.

With the advanced port scanner, a network admin can view the Port Summary by clicking on the port address. This summary displays the details of ifIndex (interface), ifName, ifDesc (description), ifType, Port Speed, Port Availability, Admin Status, and more.

Custom alerts and email notifications.

The network port scanner software raises alarms regarding the change in behaviour of ports. Mail servers can be configured to receive alerts via email notifications. This allows the network admin to monitor and diagnose a network more efficiently. Alerts are generated when:

  1. There is a change in the state of the port from Transient to Available.
  2. There is a change in the state of the port from Available to Used.
  3. Multiple devices are detected in the same port.
  4. The device connected to a port has been changed.
  5. Users move on the network.

This helps the admin troubleshoot the port monitoring issues.

Port scanner widgets.

OpUtils' port scanner tool has a collection of widgets that provide crucial information about the state of the ports at a glance. The widgets on the dashboard provide insights on:

  1. Port Availability Summary.
  2. Port Availability Summary HeatMap.
  3. Top Ten Groups with Free ports.
  4. Top Ten Groups with occupied ports.
  5. Top Ten Switches with Free ports.
  6. Top Ten Switches with occupied port.
