Free option for private live stream?

Privacy and security are the most vital features for a variety of work related live streaming tasks. For example, staff training videos which you don't want to share with public and official meetings, etc. Though private streaming using YouTube or Facebook is an option but still your data is safe. I prefer a platform which has built-in in transit encryption and putting an extra security layer of geo and ip restriction will make it safer. Password protection and two factor authentication should also be implemented. I used Streaming Video Provider to host a live broadcast and all went flawless. Choose any program you like but make sure that your application has all features discussed above.
