Free Computer Security

Keep your PC secure by updating insecure 3rd party programs installed on your computer.

We’re always harping on folks to do their Critical Windows Updates on a regular basis but what about all the other programs you’ve installed on your computer. Trying to keep all those applications updated and secure manually could take an awful lot of time and become a real hassle.

Secunia Personal Software Inspector might just be your salvation.

Secunia PSI 3.0 is a free computer security solution that identifies vulnerabilities in non-Microsoft (third-party) programs which can expose PCs to attacks. Simply put, it is scanning software which identifies programs in need of security updates to safeguard the data on your PC against cybercriminals. It then supplies your computer with the necessary software security updates to keep it safe.

The Secunia Personal Software Inspector (PSI) even automates the updates for your insecure programs, making it a lot easier for you to maintain a secure PC. Using a scanner like Secunia PSI 3.0 is complementary to antivirus software, and as a free computer security program, it’s essential for every home computer.

If you don’t want to install Secunia PSI on your home computer, there’s Secunia’s OSI (Online Software Inspector) that runs from their website.

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 CSI, 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
  • If you run the Secunia PSI or CSI – then you’re already covered


Keep in mind that Secunia OSI is a manual solution that only checks the top 100 applications while PSI, once installed, will automatically keep all your software up to date.

Either way – Secunia Personal Software and their Online Software Inspector are both FREE for home users. The Corporate products are pay per user solutions and you can get a quote right from their website,
