Secunia PSI (Personal Software Inspector) is an update tool that detects and critical patches for the programs installed in you computer. PSI scans your for the list of software installed in your system and then compiles a signature for each and every program found and sends it to the Secunia server which checks it against its database.

During the scan process, PSI follows a series of steps which includes downloading search rules from the Secunia server via secure HTTP protocols, searching files on local fixed drives, collecting information about files and the operating system, determining missing Microsoft security patches, and matching date with the Secunia file signatures engine. Once the scan has been successfully completed, a pop-up window displaying the current Secunia system score appears.

PSI prepares a security report on how many software/application requires an update. With this methodology PSI offers a complete package when it comes to the downloading of updates. Furthermore, a wizard guides the user to the suitable link-he only has to click it. PSI is the most user-friendly of all the update tool applications. The welcome screen informs the user of all relevant information, such as the last time a full system scan was run and state of their applications. If there are any security concerns, PSI will automatically alert the user with warnings.
