SNScan

SNScan is a Windows network tool whose purpose is to help you scan and detect SNMP-enabled devices on a network. It is able to indicate devices that are potentially vulnerable to SNMP-related security threats.

Simple looks

You are welcomed by a clean GUI that integrates all configuration settings in a single panel, so they are basically placed at your fingertips.
There’s no support for a help manual but the dedicated parameters are intuitive so you are not going to invest too much time and effort into the configuration process.

Scanning options

SNScan gives you the possibility to specify the hostname/IP address, enter the start and end IP addresses, as well as import the information with IP addresses from a user-defined plain text file.
Other important scanning configuration settings enable you to select the SNMP ports that you want to scan (e.g. UDP 161, 193, 391 and 1993) and use standard or custom SNMP community name. The custom SNMP names can be imported from a user-defined text file.
In addition, you can randomize the scan order, specify the timeout, start or stop the scanning task, and view the results displayed directly in the main window. The program is able to reveal details about the IP address, port number, name, and description, and lets you copy the line or IP address to the clipboard.
Tests have shown that the application carries out the scan process quickly but this depends on the range of IP addresses that you want to process. It remains friendly with system resources, so the overall performance of your system is not hampered.

Bottom line

All things considered, SNScan integrates several straightforward features for identifying SNMP-enabled devices, and is suitable especially for system and network administrators. On the downside, the utility hasn’t been updated for a while, so it may cause compatibility issues on newer operating systems.
