When COVID started, BlueJeans was our only way to meet and actually work together. Our company used MS Teams, and that solution was just not usable by our team. Things improved when we started using BlueJeans, it is just much easier to use. Being a participant on other meetings via Teams, WebEx, etc. People just struggle to use these tools (especially older ones), but that was not happening with BlueJeans.
Our team just needed to see and hear each other to collaborate. Audio breaking up was a problem on other platforms.
Also encryption and security was important to us, because of the nature of the work we were doing, and we feel secure on BlueJeans!
