Windows Update on Backup Exec 2010 Server

We've got a Backup Exec 2010 server running on Windows Storage Server 2008 R2. Our Microsoft WSUS server shows that it needs over 107 Microsoft Security updates. Our Backup Exec admin says when he checks for updates in the Backup Exec console it doesn't show it needs any. Should we be worried or is there anothe way to apply the updates? Our admin says he can't navigate to the Microsoft Update site either.
