What advantages does this offer over tools like vfense & spacewalk? How much time/effort do I save, vs deploying an in house solution using vfense (or go to an even lower level with mrepo and configuration management). With the sysward agent, I still have to install the agent, configure & test it out, open firewall rules etc etc...but most importantly, I have to send security data over to 3rd parties (sysward), which means I have to hope that sysward is also secure.
