Cloud storage services like Dropbox have changed the way people collaborate and share files, but to get the most out of them, you need to trust your data to a third-party provider. This might not be an issue for the average desktop user, but for an enterprise it may be a deal-breaker. If you don’t want to lose control of your data, yet enjoy all the benefits of an always-available and synchronized online repository, you can turn to ownCloud, an application that lets users share and sync files within the confines of your enterprise firewall on servers you control.
