Written by Chaks

Topics: Software Review, Windows

Secunia Personal Software Inspector (PSI) is a freeware tool to monitor your system for the updates available for the software installed and alert you of missing security updates. It can automatically update the installed software if the PSI is configured to auto-update mode and for those that it cannot update, it usually points you to a location where you can download the update manually. It constantly monitors your system for insecure software installations, notifies you when an insecure application is installed, and even provides you with detailed instructions for updating the application when available. To get the security information about the installed product, the tool contacts the Secunia website for the details.

Secunia PSI works by examining files on your computer primarily .exe, .dll, and .ocx files which would contain some meta information provided by the software vendor only. After examining all the files on your local hard drive(s), the collected data is sent to Secunia’s servers, which match the data against the Secunia File Signatures engine ( to determine the exact applications installed on your system. The servers push the available updates if it detects any updates.

You can configure PSI to ignore few directories from scanning by adding those directories to the Ignore list. It is also possible to set PSI not to update the software automatically by deselecting the option “Enable automatic program updates” in the configuration section. Currently the 3rd version of this tool is in beta stage. The GUI is much simplified in the 3rd version and looks as below.
