IS Security Secunia Documentation
Secunia Corporate Software Inspector
Patching third-party applications is a necessity. Out-of-date third-party software can be a source of vulnerability which could expose your computer and the rest of the computers on the network to infection. It can be difficult to keep all of your third-party software up-to-date, especially if you're responsible for a large group of computers. Much of a system administrator's time can be spent simply patching all of the third-party applications.
Secunia CSI is a tool which makes this task easier by providing you with detailed scan reports and vulnerability statistics about the hosts you manage. CSI enables you to both monitor and manage the deployment of many third-party applications. It allows you to send out patches for insecure programs through the use of the standard Windows Update Agent.
