The Secunia or Flexera Personal Software Inspector is a free security tool designed to detect vulnerable and out-dated software and plug-ins which expose your otherwise updated & secure Windows computer to malicious attacks.
Attacks exploiting vulnerable programs and plug-ins are rarely blocked by traditional antivirus and are therefore increasingly popular among criminals. The only solution to block this kind of attacks is to apply security updates, commonly referred to as patches. Patches are offered free-of-charge by most software vendors, however, finding all these patches is a tedious and time-consuming task.
Secunia PSI automates this and alerts you when your programs and plug-ins require updating to stay secure.
The free tool will scan all the installed software on your system and identify if any of them need to be updated. It will also detect and report End-of-Life programs and plug-ins. End-of-Life (EOL) programs are no longer maintained and supported by the vendor. It then supplies your computer with the necessary software security updates to keep it safe. The Secunia PSI even automates the updates for your insecure programs.
