The Secunia Online Software Inspector, or short OSI, is a fast way to scan your PC for the most common programs and vulnerabilities, thus checking if your PC has a minimum security baseline against known patched vulnerabilities.
Use the Secunia OSI to get a feel for the Secunia Software Inspector technology, then upgrade to the Secunia PSI or NSI, which covers practically all programs on your PC, whereas the OSI checks less than 100 programs.
Feature Overview:
Detects insecure versions of common/popular programs installed on your PC
Verifies that all Microsoft patches are applied
Assists you in updating, patching, and protecting your PC
Activates additional security features in Sun Java
Runs through your browser. No installation or download is required
