The ManageEngine Oputils port scanner also uses fast scan technology, making it ideal for larger networks as well. With no additional frills, the port scanner will give you a breakdown of the IP address, port status, suspected services, and possible OS in a matter of seconds. While the bundle itself may have many different tools, what makes the OpUtils port scanner stand out is its simplicity. The OpUtils bundle includes a port scanner, a port mapper (which maps physical connections on a switch), a rogue device detector, an SNMP monitoring tool, an IP address manager, and about six other network-related tools.įocusing specifically on just the port scanner, the tool has a clean graphical interface similar to SolarWind Port Scanner, which allows you to quickly pick a range of ports and IP addresses to scan. Rather than a single tool, ManageEngine has put together a bundle of tools that are designed to help technicians who are on the move and need more than just port scanning tools. Its ease of use and great interface is why this free port scanner tool is number one on our list. The SolarWinds Port Scanner tool offers a simple interface that allows you to get started right away, without having to learn syntax or leave the Windows operating system. This template can save IP address ranges and the specific ports you’d like to scan. For techs or pentesters that find themselves running these scans often, a custom config file can be saved for future use. Scanning results can be saved into multiple formats like XML, XLSX, and CSV, and support IANA port names that can be modified after the scan is finished. Knowing the operating system of a target device can help attackers identify additional entry points and vulnerabilities in context to the ports that are open on that device. ![]() In addition to ports and services, the tool also performs OS detection using its own fingerprinting method. These features also make SolarWinds Port Scanner a great choice for larger enterprise-level networks. The network sweep completes quickly and uses multithread scanning along with adaptive timing behavior to cut down on the overall scan time. Through an easy-to-use interface, you can specify a range of IP addresses or an individual device that you want to scan, and receive a readout of the ports that are open, closed, and filtered, along with the possible services those ports are using. The SolarWinds Port Scanner Tool strikes a perfect balance between ease of use and detailed port scanning analysis. In many countries running these tools without permission is considered illegal. When using a port scanning tool, make sure you have explicit written permission to run them if you are using them on a network you do not own. Running a network audit with a trusted port scanner can help identify threats and malware that may have gone undetected by traditional antivirus scans. Attackers will often use unsecured ports as entry points, as well as ways to exfiltrate stolen data. Since ports are common gateways into a network, reviewing your network’s port status and usage is key to ensuring only legitimate services are running on your network. Hackers and sysadmins alike utilize port scanner tools in a game of a cat and mouse, where attackers will try and take advantage of unsecured ports, and network administrators will attempt to lock down any ports that do not need to be open. Port scanners help give a detailed look into a network to determine which ports on a device may be open, what services they are running, and if those ports are compromised or vulnerable to certain exploits.
