GFI LanGuard provides patch management, network security, and vulnerability scanning into a unified application. The product offers short cuts to a dashboard, a place to remediate issues, agent management, and scanning. For ease of install and setup I give the product 9 out of 10. The initial scan of my five machines took almost 30 minutes, but an initial scan could be a weekend long event or more. It can assess and remediate machines using an account with administrator privileges, but scans must run each time a machine is checked.
