Hi there, I recently set up an elastix system running on a web server through VPS.net (they recently started offering a "cloud" elastix server image). It's running very well, but I have some questions regarding security... First off, VPS.net offer DotDefender firewall licenses for $15/month. Should we use DotDefender for security? Or would an alternate security/firewall suite be better fit? Or do we not need one? Also, being in a hosted environment, what steps should be taken to ensure everything is safe and secure? Any feedback and help would be appreciated! Thanks!
